What type of thumblatch do I need for my door?

Firstly, you’ll need to measure the thickness of your door.

Our Medium thumblatches work with doors up to a thickness of 55mm, and our XL versions are suitable for doors up to 75mm thick, due to the length of their thumb bar.

Once you’ve figured out what size you need, you can choose the finish and style. Our Bean thumblatches are designed to match our Penny End T hinges, and our Gothic thumblatches are designed to match out Arrow Head T hinges.

How do thumblatches work?

The handle/thumb bar is fitted to one side of the door and allows the user to depress the thumblatch. The thumb piece (or thumb bar) passes through the door and lifts the latch bar off the keep. The latch bar is the horizontal bar which is fitted to the other side of the door and is loosely screw fixed at one end to allow upward movement of the thumb bar. This means the latch bar can be lifted off the keep from either side of the door.

Staple pins and/or screw-on-staples are used to restrict the movement of the horizontal latch bar. Either can be used for this purpose.

The frame keep pin is driven into the door frame and screw fixed for safety and used to hold the door/thumblatch closed.

Can I lock a thumblatch?

Yes, of course! Simply replace your existing staple pin/screw-on-staple pin with a locking staple pin/screw-on-staple pin. This locking version comes with a metal pin attached via a leather strap and can be used to hold the door in place. You can find locking staple pins/screw-on-staple pins in the “Spares & Accessories” section of our website.
