Ballymore Spring-Loaded Caster 4-Step Rolling Ladder, 20" base, 14" top step
Spring-loaded caster ladders are rolling work ladders with spring-loaded casters used in warehouses, retail fixtures, maintenance and industrial work where mobile access is needed. Buyers choose step count or platform height (1–7 steps), tread type (perforated, expanded metal, serrated/grip strut, abrasive mat), whether a CAL-OSHA model is required, and factory-setup versus knocked-down shipping.

Start with step count or platform height. These ladders are offered in 1- through 7-step configurations and are built of steel with a 450 lb capacity. All models are gray and built to OSHA 1910.23 / ANSI-ASC A14.7; CAL-OSHA versions meet California Title 8 when required.
Tread type affects where you use the ladder:
CAL-OSHA models are required for California and Canada job sites and are selectable in the model/configuration options on applicable product pages. Most product pages (36 of 38) offer a factory-setup (fully assembled) option; the remaining pages ship knocked-down for on-site assembly.
These ladders ship factory-direct via LTL freight from Coatesville, PA to commercial addresses. Lead times vary by model; check the product page or ask a specialist for current availability and shipping details.
CAL-OSHA versions are required for California and Canada job sites; those models are offered on 6 of the 38 product pages and are selectable in the model/configuration selector.
Most product pages (36 of 38) offer a factory-setup, fully assembled option. If a page does not offer factory setup, the ladder ships knocked-down for assembly.
All listed spring-loaded caster ladders have a 450 lb load capacity.
Perforated is general-purpose; serrated (grip strut) is for wet or oily floors; expanded metal lets debris fall through; abrasive mat is for quieter or cleaner areas.
