When RV cabinet, closet or drawer latches fail, magnetic catches — which are easy to install — can be called into service.
Given their use, it’s not surprising that RVs seem to need repairing on a regular basis. A case in point: hammered by travel along rough roads, it didn’t take long for the latch on a friend’s sliding wardrobe door in the bedroom of his RV to give up the ghost. As a quick fix, three pieces of hook-and-loop fastener material were stuck to the door frame and closet structure to prevent unwanted opening. The makeshift “latch” worked okay for a while — but eventually the material lost its “stickiness” and allowed the closet door to wander when on the road. Looking for a logical alternative, I found a magnetic cabinet catch that could be installed easily and hold the door closed. You can buy a six pack of these catches for only $7.99 on Amazon (“Cabinet Magnetic Catch Jiayi 6 Pack”).

The most appealing feature of the product was its ability to stick matching catch plates to the door and wood closet structure with two-face tape that came with each kit. It’s a good idea, but unless the surface is perfectly flat, smooth and cleaned, the tape will eventually let go. Therefore, screws were also used to secure the latches. Unfortunately, the provided screws are pretty soft and can break easily when driven into the wood or metal; it’s critical to drill perfectly sized pilot holes and refrain from using a screw gun for final tightening.

The original latch that kept the wardrobe closet door from sliding open while on the road crumbled after only a few months. As a stop-gap repair, hook-and-loop fasteners were attached to the edge of the door and closet structure. They worked for a while, but eventually lost holding power.

Magnetic cabinet catches, which are nothing more than two plates that are attracted to each other, were installed as a more permanent solution. The kit (purchased on Amazon for $7.99) includes six pairs of plates, pre-cut two-face tape and screws.
Once the hook-and-loop material was removed, all surfaces were cleaned with alcohol and the first plate was attached to the closet frame using the two-face tape. The location for the matching plate was marked on the door and stuck to that frame. In order to provide enough strength to hold the closet closed, two catches were installed, which proved to be successful; the closet door never opened by itself when on the road.

One of the plates was “stuck” to the closet structure first. The two-face tape will only hold if the surface is flat and smooth. It was necessary to install two catch sets on the wardrobe closet to provide enough strength to hold the door.

After marking the corresponding location for attaching the second plate on the wardrobe door, it was “stuck” to the frame with the two-face tape. The screws were installed later, which required precision centering of pilot holes before driving the screws; the holes were countersunk to keep the screw heads from protruding on the plate surface and reducing magnetic strength.

The gap between the wardrobe door and cabinet structure remained fairly small when the catch plates were mated in the closed position.

These same catches can be used on any cabinet door or drawer; coincidentally, the factory latch on one of the galley-hutch drawers broke, which set up a perfect test bed for installing additional magnetic catches. It was a very easy task. The magnetized catch was placed on the drawer and the other on the opposing cabinet structure using the two-face tape. No measurements were needed; the two plates were lined up and attracted to each other and the tape backing removed. Then, both pieces were stuck to the edge of the cabinet structure and the drawer was closed, seating the plates. After allowing the tape to set up for 30 minutes, the drawer was opened to separate the plates and determine if there was enough strength to hold it shut — and it held nicely, although two would likely be required for larger drawers. Later, the screws were driven through the plates, which required precision centering in the hole to keep the plates perfectly flat against each other. If not, the amount of magnetic strength will be reduced, which could lead to unwanted opening of the drawer.

A magnetic catch also was installed on a galley hutch drawer after the factory latch broke. It was easy to install without taking measurements, but two of the screw heads twisted off when driven into the wood so screws were left out and the drawer remained closed with only one catch-plate set in place. It may be necessary to reapply later — using better quality tape or glue — if the supplied two-face tape fails down the road.

Because the provided two-face tape is not the most robust on the market, it can be replaced with 3M VHB tape for anyone opting to not use the screws, or the plates can be glued in place.

These magnetic catches are a good alternative to locating and installing various latches for closet doors, cabinets and drawers, and are inexpensive enough to keep in your spare parts bin while on the road — you know, just in case an original latch fails.
