Surface Bolts

Surface bolts are fitted to the face of a door and slide into a keep on the frame, head or floor to hold the door securely shut. They are particularly useful for double doors, French doors, gates and sheds where a simple surface-mounted locking bolt is required.

Surface Bolt Buying Guide

How does a surface bolt work?

A surface-mounted door bolt fixes directly to the face of the door and slides into a keep fitted to the frame, head or floor. Because it does not require a mortice to be cut into the door edge, it is straightforward to install.

What length surface bolt should I choose?

Surface bolts are available in different lengths, from around 100mm up to 355mm. Choose a longer bolt where greater reach is required, particularly on tall or heavier doors. Check the available fixing space before ordering.

Where are surface bolts used?

Surface bolts are commonly fitted to the inactive leaf of double and French doors, as well as gates, sheds and outbuildings. They hold one door leaf securely in position while the other leaf remains in regular use.

Which finish should I choose?

For exposed or external applications, finishes such as solid brass and stainless steel can be suitable. For internal doors, choose a plated finish that complements your existing handles, locks and other door furniture.
