Product Description

GN437 Hinge, Zinc Die Cast, with Adjustable Friction 

The set screw fitted to these hinges, GN 437, allows the mobility of the hinge to be changed, giving a constant and adjustable braking torque across the whole of the hinged range. The swivel motion of doors and traps is inhibited and inadvertent motion and slamming is prevented.

The friction torque is accomplished by two slim friction cones being braced against each other. Another effect of this type of hinge is that there is no play in axial or radial direction of the hinge. The large friction surface and the low-wear synthetic material of the friction cone guarantee a long service life with virtually constant friction force and the resulting inertia.

Black, RAL 9005, textured finish SW.

Silver, RAL 9006, textured finish SR.
