On side-hung windows supported by standard butt hinges (and in some cases friction stays) the friction arm offers distinct advantages over the conventional peg stay. It is totally concealed when the vent is closed and offers no internal obstruction when opened.

For large top hung vents the friction arm can be used as an extra support by fitting it below the existing friction stay. This has the effect of limiting the opening as well as adding greater stability to the window.
