The 4” Wheel Cups for Secondary Stretcher by Ferno delivers a professional emergency vehicle securement layout engineered to provide stable anchorage for transport caster wheels inside ambulances. Designed for modern transit fleets, medical response units, and multi-patient disaster vehicles, this low-profile recessed positioning system prevents unlatched secondary cots or stretchers from rolling or shifting during transit. The specialized tapered pocket layout guides caster wheels cleanly into place to isolate lateral movement, giving emergency response crews a dependable and space-efficient floor hardware asset that ensures patient and equipment containment during demanding road maneuvers.
