1. Slingco’s Fiberglass Extension Arms and any other Slingco parts and accessories listed in this manual are intended for temporary support of energized conductors to provide clearance around work areas. Temporary support and use is defined as using this product no longer than 72 hours under clean and dry conditions. Use under any other conditions or for a longer period of time will result in performance loss.
   NOTE: If performance of the materials degrades, it could lead to electrical tracking or other possible ‘stress’ to the product’s fit, finish and performance. The electrical tracking could result in a phase-to-phase or phase-to-ground electric arc, damaging equipment and possibly causing injury to anyone in the area.
2. Do not mount any other equipment or products to the Fiberglass Extension Arm other than wire holders and crossarm brackets.
3. The Fiberglass Extension Arm is never to be used in the case of hurt man rescue. The arm is NOT rated for human support.
4. Fold unused bracket toward pole (see diagram).
