WRS Truth 20" Support Arm - .235 Brackets

Friction Adjusters (Support Arms) are used either as a Limit Device, or for additional friction in conjunction with certain types of hinging on projected windows. By tightening a screw in the sliding brass shoe, a homeowner can easily adjust the tension required to open and close the window. When used as a Limit Device, the hardware is designed to restrict the opening on projected or casement windows. This mechanism automatically stops the vent at a safety position as required by the user, or required by law. For cleaning and ease of window assembly, a key may be used to release the window to its maximum opening. This support arm measures 20" in length, features a stainless steel construction and is compatible with a .235" Bracket. Support Arms sold individually. Hardware not included.
