A three tier stainless steel mobile step unit supplied with anti-slip treads. This construction is fully welded for maximum strength and mounted on four 80 mm spring loaded castors with grey, non marking, rubber tyres. Once a weight is applied to the unit the castors retract inside their housing allowing the rubber stops to make contact with the ground and provide a sturdy base support. Not high enough? We also supply a four and five step version found in the related products section. Get in touch with our friendly sales team today for more info.
