R12 door restrictors fit in the channel of the door which is found around the perimeter of the door leaf. Just position to the instructions we give and the device is easy to install.
A snatch-to-close feature and a clip to remove for fully extended opening exist with these restrictors.
Use them on uPVC doors or even timber doors due to their slim build (some routing may be required).
If you prefer a simpler method why not tie back your door using our range of cabin hooks. These are easy to fit and allow the maximum opening of the door.
