Description
3 Series Wing Hinge is a concealed hinge used to create a hidden pivot point between two SlotPro aluminium profiles or panels. This 3 Series Wing Hinge mounts inside the profile, allowing doors, panels, and access covers to close with a clean external finish.
The 3 Series Wing Hinge is fully hidden from the outside when closed, helping improve security and prevent outside removal. Once installed with the matching hinge pin, cover caps, slot nuts, and countersunk screws, one profile or panel can swing open like a door. This product includes the hinge body only, required hinge pin, cover caps, and fixings are sold separately.
