The Harloff-70300006 Caster Plate provides vital structural mounting support engineered specifically for pontoon-style Classic series mobile medical carts. Constructed from heavy-gauge, powder-coated steel, this heavy-duty reinforcement plate attaches directly to the lower base frame, creating a rigid interface between the cart chassis and swivel caster wheel assemblies. By absorbing operational load stress and impact shock during cart transport across elevator thresholds and facility expansion joints, it prevents chassis twisting, frame flexing, and premature wheel failure. Designed as an exact-fit OEM replacement component, this caster mounting plate allows facility maintenance technicians and biomedical engineering teams to repair damaged lower corner mounts, restoring smooth maneuverability and weight distribution across busy hospital corridors.
