Restrictor Friction Hinge

Print this Page

The Restrictor Friction Hinge is a simple and effective way to restrict the initial opening of a window to a maximum of 100mm, in accordance with BS8213-1:2004. It is able to withstand the load bearing forces required in BS EN 14351 and BS6375-2. The unobtrusive mechanism, which is integral to the hinge and designed to be less tempting to children, requires a level of dexterity to operate and two hands are required to coordinate opening, giving added protection. An automatic reset facility ensures safe operation at all times.

Technical Data

The Restrictor Friction Hinge is manufactured in stainless steel and offers excellent load bearing characteristics. It has identical geometry to standard Nico friction hinges allowing it to be fitted in conjunction with them if appropriate. It is available in 13mm non handed and 17mm handed stack heights. Slotted fixing holes in the base channel and sash bar, with a final fixing hole in each component, provide maximum sash/frame adjustment. The all metal end-cap is riveted on to the hinge for extra strength and rivet holes are counterbored in a 3 stage manufacturing process. This means parts are manufactured to tight tolerances and ensures reliable operation of the finished hinges.The friction slide is made from high strength glass reinforced nylon with an adjustable resistance screw to regulate friction. It is recommended that fabricators check all restricted openings to ensure they comply with Building Regulations, as profile variations may affect 100 mm opening.

All hinges have been endurance tested with their maximum load carrying capacity to 30,000 cycles in the Nico Test Centre.
