N.V.T. (Holdings) Ltd logoSOSS Invisible Hinges Technical InformationSOSS Invisible Hinges Technical Information
The SOSS range comprises of hinges from light duty, non-load bearings through to heavy-duty door hinges, so whatever your requirements, you will almost certainly find a SOSS hinge to match. SOSS' s finely engineered link construction reduces friction and makes for light, easy hinge and door opening.

All SOSS Invisible Hinges are fully reversible. They are made from either high quality steel or heavy duty zinc alloy castings for all round strength and endurance. Once installed, the hinge is firmly anchored in a mortice which relieves the screws of much of the strain of supporting the door.
