Z105 Surface Fixing Friction Door Stay

The Z105 is a heavy pattern surface fixing friction door stay. it is used to restrict the door opening to a certain angle, helping to prevent damage if the door is affected by a heavy force such as wind. 

Suitable for external use, the mild steel units are zinc plated before being silver sprayed. The Z105 is also available in barrelled finish stainless steel for prolonged use in corrosive environments. Both version have the same dimensions - 229mm from centre to centre of arm. To adjust the friction, tighten or loosen the locknut on the friction box using a spanner. 65mm spacing from the hinge axis will give an opening angle of approximately 90°. Decrease this dimension for greater angles (e.g. 95-100°) or increase the dimension for restricting the door to approximately 80-85°.

If more or less friction is required, adjust the hexagonal bolt accordingly. It is important that the friction is checked and adjusted regularly. This device is designed to control the speed of opening and closing: It is not a door stop or holder. To prevent damage to the door or adjacent cladding, a supplementary door stop should be fitted, particularly if the building is in an exposed position.

Since it is a surface fixing product, this door stay is suitable for use on both timber and steel doors.

Both Z105-Z and Z105ST have been successfully tested to Grade 4 (240 hours neutral salt spray exposure) in accordance with BS EN 1670:2007 Building Hardware – Corrosion Resistance.
