Universal Scaffold & Equipment's Bil-Jax-Style Ladders are 17" in width and have a shorter ladder bracket arm length than the Universal System Scaffold Ladders. With rung spacing every 12" and nuts & bolts on the ladder coupling pins, the Bil-Jax-Style ladder is designed for optimal access capabilities. Ladders are interconnected and attached to the scaffolding by use of a clamp-on scaffold ladder bracket. Universal's ladders meet and exceed all requirements from OHSA and ANSI standards. The 17" wide access ladders come in lengths of 3' and 6' so you can reach the needed heights required. The ladders are fully hot-dip galvanized.
