U-Channel Patio Door Bumpers by LAMATEK

Use our standard U-Channel (pictured left), M-Channel or Micro-U Channel (below) patio door bumpers to provide a cushioned, clean stop for moving door panels. Also known as patio or sliding door shims, our universal PVC stoppers are designed to lock into place on sliding door tracks. Door bumpers absorb shock and sound to provide quieter sliding and minimize rattling or slamming doors. They also protect the door track frame and glass panel from impact when sliding doors are being opened.

Our patio door bumpers lock into place with a little bit of pressure. The soft fins on the sides snap into place on the patio door track to provide a clean secure fit. Patio door bumpers are easier to install when one side is inserted and then the other is snapped in place, rather than trying to lay the bumper flat and apply pressure in the middle.


Patio door bumpers are in stock and ready to ship immediately! Supplied in cartons of 200.
