    Off set window locking mechanism

    Posted by Bob Baker on Oct 09, 2019

    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.

    window locking system

    Posted by simon on Mar 23, 2018

    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

    Fantastic product

    Posted by Joan on Apr 28, 2015

    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

    Does the job

    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.
