The Harloff Pull-Out Stoppers for Trays are vital safety accessories designed to prevent modular storage trays from accidentally sliding completely out of medical carts and supply cabinets. Engineered to snap or clip directly onto standard Harloff exchange trays and MedStor Max modular tray frames, these durable polymer stops engage with the internal side rails of the cabinet or cart. When a clinician rapidly opens a tray during a procedure, the stoppers catch at the maximum extended position, holding the tray securely in place while allowing full, unhindered access to stored items. This simple yet critical safety feature protects expensive medical consumables from dropping onto the floor, prevents supply contamination, and reduces the risk of injury in busy clinical environments.
