Refrigerated Truck Door Retainer Seal
U-channel-mounted sealing profile for refrigerated truck doors, insulated vehicle bodies and cold-storage transport equipment.
Match the U-Channel Before Checking Lip Contact
The mounting section must engage the existing retainer without looseness, distortion or excessive installation force. After confirming the channel, check that the flexible lips reach the mating frame throughout the door perimeter and closing cycle.
Send a perpendicular end-view of the old seal and retainer. Measure the retainer width, height, wall or flange thickness, locking features, free lip reach and closed-door gap.
