GN 129 Hinge, Steel, Zinc Plated With Nut & Bolt Mounting
Hinges GN129 are used for doors which are flush with the frame on the outside. The hinges are normally arranged to the side of the door.
In the two-part design, the door can be unhinged with two identically arranged hinges.
The three-part hinges, which generally cannot be unhinged and are mounted inside, are suitable for doors and flaps which, as an anti-tamper precaution, must not be dismountable from the outside.
