Retrofit Caster Kit for 3-Step Poly Step Stool – Hard Rubber

Overview Barron Equipment and Overhead Door carries the hard rubber retrofit caster portability kit for 3-step nestable poly step stool models in the SPN series. This kit adds rolling mobility to an existing step stool so workers can move it between tasks without lifting or carrying it. The casters attach to the base of a 3-step poly step stool that is already in service, making it a simple upgrade that does not require a new unit. The SPN-3-PO-RF features 3-inch by 1-inch hard rubber casters in black. The kit ships with an approximate weight of 7 lbs and is covered by a 90-day limited warranty. Assembled dimensions are 3 inches deep by 3 inches wide. This retrofit caster kit is built for facilities that want to improve step stool portability without replacing the entire unit. Features and Benefits This caster portability kit shortens the time it takes to move a step stool from one work area to another. Instead of picking up and carrying the stool, workers can simply roll it into position. This reduces the amount of bending and twisting needed during repositioning, which helps lower physical strain across shifts. The hard rubber wheels roll smoothly on a variety of floor surfaces, including concrete, tile, and sealed flooring commonly found in warehouses, stockrooms, and production floors. Installation is simple and designed for immediate use. The kit attaches easily to existing 3-step poly step stool models with no special tools or complicated steps. The robust design holds up to daily use in demanding work settings. The base 3-step nestable poly step stool supports a 500 lb. uniform capacity. The caster kit is built to work within that same range. Because this is a retrofit accessory, facilities can upgrade step stools already on the floor rather than buying new units with casters pre-installed. Applications The retrofit caster portability kit is a good fit for any workplace where 3-step nestable poly step stools are moved between locations during the workday. Common environments include: Warehouses and distribution centers Stockrooms and retail backrooms Maintenance and repair areas Production and assembly floors Commercial kitchens and food service areas Hotels and hospitality facilities Municipal and government buildings Shipping and packaging areas Adding casters to a step stool makes it easy to reposition between aisles, workstations, or departments. This is especially helpful when multiple workers share the same step stool across a shift. Instead of stopping work to carry the stool, teams can roll it to the next task and get back to work faster. Nestable poly step stools provide lightweight, high-visibility access across many commercial and industrial workspaces, and the caster kit makes that access even more flexible. Selection Assistance Barron Equipment and Overhead Door offers guidance to help customers choose the right step stool accessory for their setup. This retrofit caster portability kit is designed only for 3-step nestable poly step stool models in the SPN series. It is not compatible with 1-step or 2-step models, which each have their own version of the caster kit (SPN-1-PO-RF and SPN-2-PO-RF). Facilities that also want handrails, a back rail, or all accessories at once can look at the individual retrofit handrail kit (SPN-3-YL-HR-RF), the retrofit back rail kit (SPN-3-YL-BR-RF), or the All Options Accessory Kit (SPN-3-YL-AOK). The All Options Accessory Kit bundles handrails, a back rail, and casters into one package for convenience.
