Like many RVers, I've been frustrated by shifting weight and uneven surfaces that make cabinet latches hard to open or break. I think I have the solution.
Magnetic cabinet latches.
The video shows you how they attach and work.
I now have them on all my cabinets and since they were installed, not one cabinet has broken or opened when it shouldn't have.
I have been unable to find them individually available for retail. The source for the latches I found is Leisure Products of Canada. They ship wholesale to Canada and the U.S. but a minimum order is for 48 of the units. They have a suggested retail of $7.95 each. The one I have is rated at 40 pounds. It is PM2001LX.
I'd buy a bunch and stock them on roadtrekingstore.com but by the time you add the minimum $5.25 Priority Mail shipping fee, it would end up costing over $13 to get one.
But you may find another way to get them. Here's a direct link to the product: http://leisureproductscanada.com/pdf/Magnet-Clasp-Order-Form-2014.pdf
