A touch latch requires no exterior hardware. When the cabinet door is touched just over the latch, a spring pops the door open enough so the lip can be grabbed and the door pulled open. A touch latch also has a magnet to hold the door in place when it is closed. Two small tips on the magnet plate help determine where to install the magnet on the inside of the cabinet door. Place the magnet plate on the opposing magnet and press the back of the door against it. If the cabinet is made of soft wood, the tips will make impressions on the door to indicate the placement of the magnet plate. If the cabinet is hardwood, use a pencil to draw on the tips. Then, when the back of the cabinet door is pressed against them, two pencil marks on the door will indicate the area where the magnet plate should be positioned. If the pencil marks are not visible, try drawing on the tips with lipstick.

A roller catch has two rollers that interlock with a U-shaped channel that fits onto the door. Try the lipstick trick to find the place to put the U-shaped piece on the door.

A magnetic catch is similar to the touch latch, except it has no spring. With this catch, the cabinet door needs a handle so it can be opened. Instead of two tips as locators, the plate on the magnetic catch has two bent corners to facilitate orientation.
