Direct Answer
A hinge side arm is a metal component that connects a window sash to the frame, allowing the window to open and close smoothly while supporting its weight. It helps keep the window aligned, improves security, and ensures a proper weather seal. Choosing the correct hinge side arm depends on the window type, hinge size, material, and weight capacity.
Complete Guide to Hinge Side Arms
A hinge side arm is one of the most important parts of a casement or top hung window. Although it is often hidden from view, it performs the critical job of supporting the window and guiding its movement every time it is opened or closed.
A damaged or worn hinge side arm can make a window difficult to operate, create gaps that allow air or water inside, and place unnecessary stress on the locking system.
At Jobel Hardware, we supply high quality hinge side arms for aluminium, uPVC, and timber windows. Whether you need a replacement hinge for a single window or hardware for a complete construction project, we offer durable products designed for long lasting performance.
What Is a Hinge Side Arm?
A hinge side arm is part of a window hinge assembly that supports the moving sash while allowing it to pivot smoothly.
Its main functions include:
Supporting the weight of the window.
Maintaining correct window alignment.
Allowing smooth opening and closing.
Reducing stress on window locks and handles.
Improving weather sealing.
Extending the lifespan of the entire window system.
Without a properly functioning hinge side arm, even a high quality window will struggle to operate correctly.
