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).

    Great Product

    Posted by Mahmoud Massoud on Nov 18, 2019

    my gearbox was broken and I requested this is a replacement it was exactly what I had, the instructions on the website on how to order and how to fit it was really very helpful as I did the job by myself and saved the money and time. I have more windows that have issues so for sure I will buy again more stuff from them. shipment and delivery was fast and easy.

    Window bolt gearbox

    Posted by Alan Jenner on Apr 15, 2019

    It&#039;s easy to set up (once you have worked out how) and easy to fit. It does the job well at a reasonable price. It&#039;s durable in normal use so 4 stars. for 5 it would have to be indestructible.

    Posted by Vic Graham on Feb 21, 2019

    I bought this Saracen Window Lock after seeking advice from Handles and Hinges to replace my broken Saracen Window Lock part number 56068 which was no longer available.
    It arrived very quickly and is just the job

    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.
