Ordering the correct hinge

This hinge has a 17mm Stack Depth (see C below). We have a seperate 13mm Stack Depth hinge if required. To order the correct hinge you must be aware of the following choices:

1. Hang Type - Top Hung (swings from top with handle on the bottom of the sash) or Side Hung (swings from one side with handle on opposite side)
2. Hinge Length - length of the part that fixes to window frame (see B in diagram below)

This hinge is 18mm wide (see D in diagram above). It is the most common width and used for the vast majority of modern uPVC and aluminium windows. We recommend that you check this measurement, some older window frames may require a size of 14mm, this is quite rare.

Common symptoms of failing friction hinges

• Difficulty opening and closing window
• Window not closing tightly into frame
• Draughts through closed window dispite gaskets in place
• Window fails to stay in position when partially open

If you experience any of the above then you should consider repairing or replacing the hinges, before the situation gets worse and also becomes a security risk.
