FLEXBRACKET
Benefits:
• 360° Flex • For use in heavily treed areas • Bracket flexes under impact or heavy
loads • Effective in minimizing cascading due
to ice storms
Application:
• Gains approximately 6 inches of pole space
• If permanent deformation occurs, circuit stays intact
• If load does not exceed the yield strength of the material, bracket will return to original position when the
