MasterStep 2-Step Rolling Ladder

The Cotterman MasterStep is a two-step steel rolling ladder with an 18-inch platform height designed for office and light-industrial access. Spring-loaded casters lock automatically when weight is applied, providing a stable work surface at the top step. The powder-coated gray frame supports a 450 lb load capacity.

Sustained-load behavior

Under continuous use the spring-loaded casters remain engaged, preventing unwanted movement while a worker stands on the 16-inch wide top step. The rubber-mat tread maintains grip over repeated cycles, and the powder-coated steel frame resists deformation at the rated 450 lb limit. The 25 lb net weight keeps the unit manageable for frequent repositioning.

ANSI OSHA compliance limits

The ladder meets ANSI and OSHA requirements for a two-step rolling platform with an 18-inch top step height and 8-inch depth. Base dimensions of 22-inch width by 20-inch depth define the minimum floor footprint needed for stable operation. No higher reach or additional step configurations are covered by this model's certification.

Questions about this item

Does the spring-loaded caster system make noise or shift when I stand on the 18 in platform all day?

The spring-loaded casters retract under your weight, locking the 16 in wide steps firmly in place so the ladder stays silent and stable during extended use.

What floor type do I need so the 22 in wide base and 20 in deep footprint won't slide?

The rubber-mat treads and spring-loaded casters grip best on clean concrete, tile or low-pile carpet; loose rugs or wet epoxy can let the 25 lb frame shift.

Will the 450 lb rated steel frame damage the finish on my older wooden rolling scaffold if I store them touching?

The gray powder-coated finish is non-marring, so contact with painted or varnished wood on older equipment will not leave marks or scratches.
