Identify RV Designer Compartment Cam Locks by Key & Length
Compartment cam locks can look alike even when they use different key families or barrel lengths. This guide separates RV Designer's Ace-key four-pack models from the individually supplied standard-key locks, allowing you to identify the original number before evaluating a replacement.
Identify the key type and package
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.
Match the stamped MPN and cylinder length

| L327 | 7/8 in | Ace-key cam lock | 4 |

Identify a replacement before fitting
- Look for the original part number or packaging. If it is missing, carefully measure the cylinder length rather than the outside face alone.
- Identify the intended Ace-key or standard-key family. Locks with the same body length do not necessarily share keys or cam arrangements.
- Check the cam, tailpiece, retaining nut, key, weather seal and the condition of the compartment door opening.
- Confirm key operation and whether a particular model retains the key in the unlocked position; don't assume this applies across the series.
- Review the exact listing for condition, key inclusion, installed cam and available hardware. UsedRVParts viewing or pickup in Kelowna is by appointment.
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.
Find the matching lock by its manufacturer number
Check the specific listing for the actual keys, cam and fittings included.
Other compartment hardware
For a different locking and striker arrangement, see the RV baggage-door latch and cam-lock parts reference. Compare the exact system before changing manufacturers.
