Epoxiglas Hook Ladders have many applications in high voltage maintenance to position linemen in the most advantageous working location, making line repairs possible at otherwise almost unaccessible places. All hooks are formed from 1"-diameter tempered steel and can be swiveled to best fit various angles on the structure. Steel chains clip to the hooks to assist in securing the ladder to a support. Rung material for both rated ladders are 1.25" Epoxiglas, sand coated.
