Top Hung Projecting Hinge is one of the products of VALIFORCE Series. It is a sophisticated design which balancing the change of gravity is adapted into the hinge construction. in another word, the Sash can stay by itself at any angle when opening from 0-30 Degree. It is not necessary to add the friction stay device to balance the Change of Gravity. With the unique design, the opening and closing force is less than 5KG even with a large size of window.

Product Description：

1, Stay at any angle without needing to add extra friction supporter.

2, 80 KG of loading , safe guarded by drop testing, i.e. taking away one hinges and let one hinge alone to hold the sash after push out the sash .

3, Horizontal adjustment +/-3mm , Height Adjustment +/-2mm.

4, Excellent corrosion resistant capability. NSST 720 hours according to ISO 9227.

5, Friction is adjustable .

6, fully engagement of fittings and profile. The guide rail and back plate are inserted into profile. Then it is tightened by clamping, instead of self-tapping screw. This is why the hinges improve the safety of sash.
