Espag Lock Backset Measuring Guide
SIMPLE STEPS TO HELP YOU CHOOSE THE CORRECT FOR YOUR WINDOW LOCK
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).
*Sizes over 800mm are available in the links below.
The company web site is very good at identifying the part you need, the locking mechanism was not a direct replacement, I knew this when ordered, so required re- positioning of the window locking plates. Again I knew I would have to do this and whilst this was a bit fiddly the window now locks as it should. My only disappointment was finding the locking mechanism is not made from stainless steel but coated mild steel, how long before it starts to rust? Hence my 4 star rating.
Note from Handles and Hinges: unfortunately the manufacturer do not offer a stainless steel option.
this is the first time I have used this company.
Website very helpful and able to select correct mechanism for oldish window .
Only adjustment was to move keepers out by a few mm's as the window was shutting too tightly.
Will use again when needed
Very impressive organisation Good product well priced and delivered quickly
Would recommend to anyone
dont usually do this but excellent site good easy checkout delivery charge good and got here very quickly considering time of year well done
Brilliant ! Easy to order - instructions on how to measure are comprhensive. Website simple to use. Does the job at a very good price. Delivery on time. I highly recommend this company. The best.
THANK YOU FOR THE ADVICE. YOUR WEB SITE SAID EVERYTHING.
Our window locking mechanism had been sprained and worn, so needed replacing. No-where had the same mechanism as ours but handles and hinges have a very helpful site and very helpful staff and we were able to find one that with a little bit of adjustment, fitted perfectly. We are now able to close the window properly again, without having to call in the experts. Delivered in record time too. Thanks
This replaced the existing window mechanism. It works very well although I had to chisel the upvc to make the Chanel that it sits in as it was not wide enough. This is probably because of my old windows. Very good value for money.
Every time i need some awkward part or lock this is the place to go.
nothing to much troble.
