Support Arm

Safety Products and Limiters

Support Arm

Support arms are used on top-hung windows to provide a "hold open" device to each side of a open sash. They are available in a variety of lengths to provide various opening amounts (depending on mounting position). Support arms open to full extension and then automatically lock into place. The window is then pushed open to unlock and then the support arm will allow the window to close once again. They are only available in stainless steel. They should only be used in pairs.
