R&P Knowledge Hub
Cam-action door latch systems use rotating latch rods that engage top and bottom keepers to secure trailer doors. The bottom keeper provides the anchor point that the cam latch hooks into when the handle is rotated closed. Proper keeper alignment is important to ensure the latch engages smoothly and maintains door tension during transport. When replacing a keeper, installers should confirm mounting hole spacing and overall dimensions to match the original latch system.
