RV Designer Cam Locks: Ace-Key Four-Packs vs Standard Key
Replacing an RV baggage or utility-compartment lock starts with the correct cylinder length and key family. RV Designer offers Ace-key cam locks in four-packs and standard-key versions sold individually. This guide compares seven numbers and highlights the additional mounting and cam checks needed before buying.
Ace-key sets versus individual standard-key locks
L325 / L327 / L328 · Ace-key
These RV Designer combo cam-lock models are supplied in four-packs. The three lengths are 5/8, 7/8 and 1-1/8 inches. They are not simply four-packs of the separately numbered standard-key family.
L545 / L547 / L548 / L549 · Standard-key
These are individually sold compartment cam locks in 5/8, 7/8, 1-1/8 and 1-1/2-inch lengths. Match the existing cylinder and key system before selecting a replacement.

Check fit before installing a new cam lock
- Measure the existing cylinder or barrel length to select between 5/8, 7/8, 1-1/8 and 1-1/2-inch versions.
- Check the compartment door thickness and the existing mounting-hole dimensions. Cylinder length by itself does not prove the lock will fit.
- Confirm the original cam or tailpiece offset, rotation, key-removal behaviour and closing direction against the selected lock.
- Distinguish four-pack Ace-key models from individually sold standard-key locks. Do not assume all locks in a family use the same key as previously installed hardware.
- Test the lock and compartment-door seal after installation, without forcing the cam against a misaligned striker.
Important: matching the advertised cylinder length is only one part of replacement selection. Confirm the keying arrangement, cam geometry, rotational travel, mounting hardware and the actual compartment door thickness before ordering.
