Heavy Duty Tubular Mortice Latch

 Internal doors tend not to be  locked and work with a simple tubular latch set into the door, known as a tubular mortice latch.

It's important that this latch is sprung strongly enough to return the knob or lever handle to the closed position. After time this spring will weaken. You've probably all seen doors with sagging levers. 

We recommend and supply a British made  Heavy Duty tubular latch for our knobs and levers. A tad more expensive but you certainly notice the difference and feel the quality of the action .

They come in several lengths. For a lever handle we recommend the latch with an 80mm overall body and a 60mm backset. The back set is the distance between the edge of the door and the spindle of the handle or knob.  We recommend a longer body and backset when using door knobs, to avoid scuffing your knuckles on the frame when closing the door .
