uPVC Door Restrictor Stay with Hold Open Function - 90 Degrees - for uPVC, Aluminium, French & Patio Doors

Perfect for what I needed. I have got a few doors around the house that I need to restrict but also have the ability to lock open and open fully when needed. These do the trick. They are well made, fit all my door profiles and the operation is spot on. Highly recommended

Our patio door sliders ha broke due to the high winds earlier this year. This was so easy to replace took all of 10 minutes. Dead straightforward forwards, strong and now provides even better protection for out door against the wind!

Replacement for the OEM fitted door stay. Great quality. Fits nicely, and easily adjusted with the screw on top. Can be a bit noisy if not oiled fairly regularly but I run it fairly tight to stop the door in the wind. Overall great value and does exactly what it needs to.

Really useful piece of kit to stop the patio doors from blowing in the wind. I agree with other reviewers that there are no fitting instructions provided with the units, so you will have to refer to the video clip on Amazon to understand how to fit them. Fitting is very easy, once you have established the distance from the door frame and use a square to obtain a 'true' 90 degree angle for the open door stop point. Then use the grub screw to set any resistance you want when opening/closing the door (none or plenty).

Just installed it, and it was very easy - using the photos in the item description here. Holds the door well enough and a simply tug releases it from the hold.
