PATENT PENDING DRYWALL SYSTEM

3. 100% FLAT STEELThe flat steel requires no extra training or special fasteners for installation. ViperStudTM is interchangeable with conventional framing components, and is easy to plumb, laser level and mark. There’s no learning curve for trades and inspectors because ViperStudTM installs exactly the same as conventional studs.

4. THE STRONGEST DRYWALL STUD The ViperRibTM technology helps to prevent "high shoulders" when finishing gypsum board and makes ViperStudTM much stronger, stiffer, and less prone to twist than the dimpled alternative product.

5. FULLY TESTED, ASTM COMPLIANTViperStudTM conforms to the following ASTM standards: • ASTM C-645 “Standard Specification for Nonstructural Steel Framing Members” • ASTM C-754 “Standard Specification for Installation of Steel Framing Members to Receive Screw-Attached Gypsum Panel Products” • ASTM E-72 “Standard Test Methods of Conducting Strength Tests of Panels for Building Construction”• ASTM E-119 “Standard Test Methods for Fire Tests of Building Construction and Materials” Fire Tested for 1 and 2 hour rated walls, with 5/8” Type “X” Gypsum Board. - Warnock-Hersey Design No. MW/WA 60-04 Assembly Rating: 1 hour wall assembly non-load bearing - Warnock-Hersey Design No. MW/WA 120-04 Assembly Rating: 2 hour wall assembly non-load bearing

1. ONE TRACK SYSTEMViperTrackTM is a high strength one track system, and works with both Viper20TM and Viper25TM studs. This eliminates SKU's from your inventory. ViperTrackTM is 100% HEMMED, making it safer than any other product offered.

2. BETTER SCREW RETENTIONIndependent laboratory testing proves ViperStudTM has a 20% greater screw retention than the dimpled alternative products. Our tests show 139 lbs of pullout force required versus only 116 lbs on the competitor’s product. No more screw spin outs to slow down your job or call backs on completed projects.

SCREW RETENTIONFOR 3 5/8” STUD (25 ga. equivalent)

Finally, a stronger steel drywall framing stud and track, without all the speed bumps. It’s unique ability to outperform typical conventional and dimpled studs makes ViperStudTM the next generation in flat steel drywall framing products.

We’ve put forth a tremendous effort to develop a product that requires NO learning curve. After 18 months of extensive lab testing, field-testing, and design changes the revolutionary new ViperStudTM and ViperTrackTM was created. The patent pending ViperStud System is one of the most rigorously tested products the drywall framing market has ever seen. Thousands of hours were spent modeling and testing prototypes to make a drywall stud system that can live up to the demands of contractors and builders in the field.

ViperStudTM is the result of a forming process developed to strengthen the flat stud design, without the hassles that come with the alternative. Its ribbed flange and web, called ViperRib™, makes Viper the toughest performing drywall stud available; increasing its rigidity and strength, and helps to prevent "high shoulders" when finishing gypsum board. Even more exceptional is the high strength ViperTrackTM system. The single thickness ViperTrackTM system works with both Viper20TM and Viper25TM studs and is 100% hemmed, reducing the risk of injury from sharp edges. With greater limiting heights, better screw retention, and easier and safer installation, the ViperStud SystemTM is sure to become the preferred framing product for drywall contractors.

THE STRONGERFLAT DRYWALL STUD

A BETTER PERFORMINGDRYWALL STUD AND TRACK

ViperStudTM is an improved steel drywall framing stud and track system. Formed for extra strength and better screw retention, ViperStudTM is proven through laboratory testing to be the better performing drywall stud and track over traditional or the dimpled alternative.

1. Q: ASTM C 645 – 07 SPECIFIES A DESIGN THICKNESS FOR 25 GAUGE DRYWALL STUDS AS .0188”, YET VIPERSTUDTM IS .0155” DESIGN THICKNESS, HOW DOES THIS MEET THE STANDARD?A: ASTM C-645 – 07 Section 9.2 says “members that can show independently verified test performance that meets the limiting heights values listed in ASTM C-754 need not meet the minimum thickness limitation set forth in section 4.3 or the section properties in section 8.1.” ViperStudTM has proven this in testing.

2. Q: CAN VIPERSTUDTM BE USED WITH CONVENTIONAL TRACK AND STUD?A: ViperStudTM is 100% FLAT steel and can be mixed with conventional inventory.

3. Q: VIPERTRACKTM CAN BE USED ON BOTH VIPER25TM & VIPER20TM STUDS, WHAT THICKNESS IS IT?A: All of our testing was conducted with 0.0155“ design thickness track so one track can be used for both studs. This system testing meets the ASTM C-645 requirement in FAQ #1 for a verified test performance.

4. Q: VIPERTRACK IS HEMMED BUT MY MARKET USES UN-HEMMED TRACK, CAN I USE THAT WITH VIPER?A: Conventional un-hemmed track works with ViperStudTM.

5. Q: WILL I STILL BE ABLE TO BUY CONVENTIONAL DRYWALL FRAMING FROM MY MARINO\WARE PLANT?A: We will eventually convert all lines to ViperStudTM, but this will take time to complete. We will make conventional framing available for jobs that started with conventional and want to finish with it.

6. Q: I HAVE A JOB THAT IS SPECIFIED MINIMUM .0179” AND IT CAN’T BE CHANGED, CAN I GET VIPERSTUD IN A .0179” THICKNESS?A: ViperStudTM can be made to order in a 0.0179” thickness, but there will be an up charge over the typical pricing.

7. Q: IS AN INTERTEK LISTING THE SAME AS A UL LISTING?A: ViperStudTM was tested with Intertek Testing Labs, the Intertek listing meets the same standards of a UL listing.

Finally, a stronger steel drywall framing stud and track, without all the speed bumps. It’s unique ability to outperform typical conventional and dimpled studs makes ViperStudTM the next generation in flat steel drywall framing products.

We’ve put forth a tremendous effort to develop a product that requires NO learning curve. After 18 months of extensive lab testing, field-testing, and design changes the revolutionary new ViperStudTM and ViperTrackTM was created. The patent pending ViperStud System is one of the most rigorously tested products the drywall framing market has ever seen. Thousands of hours were spent modeling and testing prototypes to make a drywall stud system that can live up to the demands of contractors and builders in the field.

ViperStudTM is the result of a forming process developed to strengthen the flat stud design, without the hassles that come with the alternative. Its ribbed flange and web, called ViperRib™, makes Viper the toughest performing drywall stud available; increasing its rigidity and strength, and helps to prevent "high shoulders" when finishing gypsum board. Even more exceptional is the high strength ViperTrackTM system. The single thickness ViperTrackTM system works with both Viper20TM and Viper25TM studs and is 100% hemmed, reducing the risk of injury from sharp edges. With greater limiting heights, better screw retention, and easier and safer installation, the ViperStud SystemTM is sure to become the preferred framing product for drywall contractors.

3-5/8” VIPERSTUDTM

Finally, a stronger steel drywall framing stud and track, without all the speed bumps. It’s unique ability to outperform typical conventional and dimpled studs makes ViperStudTM the next generation in flat steel drywall framing products.

We’ve put forth a tremendous effort to develop a product that requires NO learning curve. After 18 months of extensive lab testing, field-testing, and design changes the revolutionary new ViperStudTM and ViperTrackTM was created. The patent pending ViperStud System is one of the most rigorously tested products the drywall framing market has ever seen. Thousands of hours were spent modeling and testing prototypes to make a drywall stud system that can live up to the demands of contractors and builders in the field.

ViperStudTM is the result of a forming process developed to strengthen the flat stud design, without the hassles that come with the alternative. Its ribbed flange and web, called ViperRib™, makes Viper the toughest performing drywall stud available; increasing its rigidity and strength, and helps to prevent "high shoulders" when finishing gypsum board. Even more exceptional is the high strength ViperTrackTM system. The single thickness ViperTrackTM system works with both Viper20TM and Viper25TM studs and is 100% hemmed, reducing the risk of injury from sharp edges. With greater limiting heights, better screw retention, and easier and safer installation, the ViperStud SystemTM is sure to become the preferred framing product for drywall contractors.

THE STRONGERFLAT DRYWALL STUD

A BETTER PERFORMINGDRYWALL STUD AND TRACK

ViperStudTM is an improved steel drywall framing stud and track system. Formed for extra strength and better screw retention, ViperStudTM is proven through laboratory testing to be the better performing drywall stud and track over traditional or the dimpled alternative.

1. Q: ASTM C 645 – 07 SPECIFIES A DESIGN THICKNESS FOR 25 GAUGE DRYWALL STUDS AS .0188”, YET VIPERSTUDTM IS .0155” DESIGN THICKNESS, HOW DOES THIS MEET THE STANDARD?A: ASTM C-645 – 07 Section 9.2 says “members that can show independently verified test performance that meets the limiting heights values listed in ASTM C-754 need not meet the minimum thickness limitation set forth in section 4.3 or the section properties in section 8.1.” ViperStudTM has proven this in testing.

2. Q: CAN VIPERSTUDTM BE USED WITH CONVENTIONAL TRACK AND STUD?A: ViperStudTM is 100% FLAT steel and can be mixed with conventional inventory.

3. Q: VIPERTRACKTM CAN BE USED ON BOTH VIPER25TM & VIPER20TM STUDS, WHAT THICKNESS IS IT?A: All of our testing was conducted with 0.0155“ design thickness track so one track can be used for both studs. This system testing meets the ASTM C-645 requirement in FAQ #1 for a verified test performance.

4. Q: VIPERTRACK IS HEMMED BUT MY MARKET USES UN-HEMMED TRACK, CAN I USE THAT WITH VIPER?A: Conventional un-hemmed track works with ViperStudTM.

5. Q: WILL I STILL BE ABLE TO BUY CONVENTIONAL DRYWALL FRAMING FROM MY MARINO\WARE PLANT?A: We will eventually convert all lines to ViperStudTM, but this will take time to complete. We will make conventional framing available for jobs that started with conventional and want to finish with it.

6. Q: I HAVE A JOB THAT IS SPECIFIED MINIMUM .0179” AND IT CAN’T BE CHANGED, CAN I GET VIPERSTUD IN A .0179” THICKNESS?A: ViperStudTM can be made to order in a 0.0179” thickness, but there will be an up charge over the typical pricing.

7. Q: IS AN INTERTEK LISTING THE SAME AS A UL LISTING?A: ViperStudTM was tested with Intertek Testing Labs, the Intertek listing meets the same standards of a UL listing.

PATENT PENDING DRYWALL SYSTEM

3. 100% FLAT STEELThe flat steel requires no extra training or special fasteners for installation. ViperStudTM is interchangeable with conventional framing components, and is easy to plumb, laser level and mark. There’s no learning curve for trades and inspectors because ViperStudTM installs exactly the same as conventional studs.

4. THE STRONGEST DRYWALL STUD The ViperRibTM technology helps to prevent "high shoulders" when finishing gypsum board and makes ViperStudTM much stronger, stiffer, and less prone to twist than the dimpled alternative product.

5. FULLY TESTED, ASTM COMPLIANTViperStudTM conforms to the following ASTM standards: • ASTM C-645 “Standard Specification for Nonstructural Steel Framing Members” • ASTM C-754 “Standard Specification for Installation of Steel Framing Members to Receive Screw-Attached Gypsum Panel Products” • ASTM E-72 “Standard Test Methods of Conducting Strength Tests of Panels for Building Construction”• ASTM E-119 “Standard Test Methods for Fire Tests of Building Construction and Materials” Fire Tested for 1 and 2 hour rated walls, with 5/8” Type “X” Gypsum Board. - Warnock-Hersey Design No. MW/WA 60-04 Assembly Rating: 1 hour wall assembly non-load bearing - Warnock-Hersey Design No. MW/WA 120-04 Assembly Rating: 2 hour wall assembly non-load bearing

1. ONE TRACK SYSTEMViperTrackTM is a high strength one track system, and works with both Viper20TM and Viper25TM studs. This eliminates SKU's from your inventory. ViperTrackTM is 100% HEMMED, making it safer than any other product offered.

2. BETTER SCREW RETENTIONIndependent laboratory testing proves ViperStudTM has a 20% greater screw retention than the dimpled alternative products. Our tests show 139 lbs of pullout force required versus only 116 lbs on the competitor’s product. No more screw spin outs to slow down your job or call backs on completed projects.
