Cheap but effective. I haven't heard a sound out of my rear table since installing this Home Depot magnetic cabinet latch. I found everything I needed (except a wooden 1/8" shim) in the cabinet hardware section for $1.38.

Everyone with a Westy knows that you can't tighten the rear table enough to keep it from knocking against the wall when the car travels over bumps and ruts, whether in town or at camp.

Be sure to buy a double-set as shown here. You'll need to cut a paint stick or other 1/8" material so that the latch can be mounted underneath the table and completely clear of the lip of vinyl edging. Notice too that the screws fastening the latch are all the way to the rear or the latch to allow the face of the magnets to contact the steel plates that will be mounted on the wall. If the magnets don't contact the steel plates squarely, the table won't hold to the wall.

 

I had to drill holes at the back of the latch as the screw slots did not go back far enough.

Once the magnetic part of the catch is mounted to the underside of the table, put the table back onto its arm and swing it into place to locate the catch places. Mark the magnet location with a pencil, and tape the strike plates to the wall. Pilot drill and install the supplied screws.

It's ready.

 

Magnets mounted to underside of table at midpoint of table edge. Make sure you mount it to the side that fits against the wall!
