What is a Mortise Latch?

When checking out the 1TouchXL or other mortise latch locks, you may wonder, “Have I ever seen a mortise latch?” These particular latches are almost always seen on office doors, hotel rooms, US doors from the 1940’s, and international style doors. They incorporate a deadbolt and teeth to create high security for these areas, where security is very important.

Major difference from a single latch:

Mortise latches tend to be roughly the size of VHS tape and needs to be inserted into the door.

USA standard mortises tend to be a little wider and international tend to be thinner.

Most USA Standard Mortise latches have ability to interchange with other major key-ways, manufactures such as Medeco, Schlage, and Yale.

The 1ToucXL Mortise LatchhXL is thinner than a typical USA standard latch and is more of a European style – it has an automatic deadbolt!

Do not assume all USA standard mortise latches are the same or are interchangeable with international. Please call a representative to see if yours is compatible.
