Shootbolt rods are available in four lengths and are simple to connect to the gearbox mechanism with easy to adjust screw thread action to suit any tolerance variations.

The deadbolt that moves in and out  of  the middle of the gearbox mechanism size can be either 9.5mm or 11.5mm. You can find the deadbolt size on the end of the latch. See picture

Espag Lock Backset Measuring Guide







To Measure the backset on your window lock you need to measure from the middle of the spindle hole to the front of the face plate. Take a look at the picture below and the red arrows show you where to measure.


The holes that the Bolts go through are a set distance and are the same on ALL window locks (43mm).

    Exact swap for original

    Easy replacement of a broken mechanism - saved the price of a new window (not to mention avoiding the mess and inconvenience). At this price, worth having one in stock for future lock failures.

    Very pleased with the service provided by Handles and Hinges. I had a bit of difficulty identifying the specific product I required but was given lots of help from their Customer Helpline. The product was delivered very promptly and was the right one. It has been fitted successfully.
