Friction Hinge, Restrictor, for Side or Top Hung Windows, Stainless Steel or Bra

Product Details

Is the Restrictor Friction Hinge 305mm suitable for side hung windows?

Yes. The Restrictor Friction Hinge 305mm 22kg 60D is designed specifically for side hung window applications, helping you control the opening movement while keeping the vent securely positioned.

How much weight can this friction hinge support?

Up to 22 kg maximum vent weight. This rating is intended for the window vent weight the hinge is asked to control and support, so it is important to check your window specification before fitting.

What does the 60 degree opening angle mean?

60 degrees is the controlled opening limit. The “60D” setting helps ensure the window opens to a defined angle, which can be useful for ventilation while preventing over opening.

What does the 305 mm length indicate?

305 mm refers to the hinge size used for side hung installations. Choosing the correct length is important for proper alignment and smooth operation, so selecting the 305 mm model is the right step for projects requiring this specific dimension.

Will the hinge hold the window part open, or is it only for closing?

It provides friction control. A friction hinge is used to hold the vent at a desired position, helping maintain stability during normal use and ventilation rather than relying on the window frame alone.

How do I identify this exact product when ordering?

You can order using the Product Part No: 911.59.128. Matching the part number ensures you get the correct hinge for your window type, size and performance requirements.

Why would I choose a restrictor friction hinge instead of a standard hinge?

A restrictor friction hinge improves control of opening. It is particularly useful when you want consistent ventilation with a defined opening limit, while also benefiting from controlled movement compared with standard hinges. If your project needs side hung control and a 60 degree opening, this model is a practical choice.
