Cam lock spins

Question

Some cam locks on my 2001 Winnebago Itasca Spirit have rounded out their holes so the lock cylinder just spins in the hole. The previous owner just cranked the cylinder nut tighter causing the fibreglass to crack. The compartment door is just foam fiberglass sandwich, so the only thing that ever gave the hole any substance is the thin fibreglass.

Anyone have any experience repairing their cam lock holes?

I had the same thing going on with my old trailer. I sold the trailer before dealing with it.

If I did deal with, I would have sandwiched a piece of aluminum between the foam and fiberglass. I would use a good bonding epoxy like JB weld or something similar. Clamp it good while drying.

I have had mine round out. I took a thin square piece of aluminum made an oblong hole to match the lock and put it on the inside of the door and held it in place with pop rivets.

I have no idea what you mean by rounded out camlock holes. My camlock barrels are circular and fit into circular holes drilled through the compartment doors. Rubber gaskets/washers prevent the lock mechanisms from spinning in the holes.

If the gasket/washers are missing you can replace them or you could even use star washers which would bite into the compartment doors and prevent the locks from spinning.

Most cam locks are in a double d hole. I would agree that the easiest way is to use a piece of aluminum with a double d hole to back up the inside but I would use double stick film like indoor/outdoor carpet tape. Weatherproof and has lots of holding power.

Here is an example of a replacement lock that shows the correct hole shape, and it also comes with an metal spiked "washer" to lock the cylinder in place.
