Door restrictors
Door restrictors can be used in PVC doors to restrict the opening angle of the door. Usually the restriction is set to 90 degrees. They can also be found in French and double doors. The restrictors fit within the door groove.
The door restrictor works by using a friction screw on a plastic slider that has adjustable tightness to increase the friction as the door is opened and closed. The restrictor will prevent the door passing beyond a certain angle and hold it in place against low to medium strength winds. A solid pull of the door releases it to close.
