Werner T7400 Fiberglass Multi-Use Twin Stepladders are added-heavy-duty tools which are ideal for commercial work and industrial use. And because they're made with fiberglass non-conductive side rails, they�re suggested for working around electricity. T7400 Series stepladders are constructed to carry two people (one per side), so whether you are wiring a new house or performing factory maintenance, a T7400 will provide a tough, safe ladder to help you get the job done. Each Werner T7400 Series stepladder gives the unique EDGE (Energy Diffusing Geometry) bracing system. This molded brace and foot-pad combination presents increased strength and better protection against damage during transit and on the job. Each ladder features an aluminum external rail shield to help protect against abrasion impairment, and shoe pads are riveted to the EDGE structure.
