Top Stay Arms

A tilt and turn window’s top stay arms are its load-bearing workhorses that connect your window sash to functional hardware. They’re like the link that connects hope and reality. These rigid linkages within the scissor hinge assembly transfer forces between the window sash and the hinge mechanism while maintaining precise geometric relationships throughout the window opening range.

Most of these components feature hardened steel construction, although some have aluminium with bearing surfaces at each end. They’re designed to withstand compressive forces and tensile loads while operating through thousands of opening-closing cycles.

Designing quality top stay arms requires balancing strength requirements with weight considerations. Stay arms mist be robust enough to support heavy window sashes yet light enough not to compromise the overall scissor mechanism. That’s why quality stay arms ensure uniform force distribution to prevent localised stress that could cause premature failures while maintaining dimensional stability (to prevent misalignment or binding).

At Locks & Handles we supply tilt and turn window parts to specialist window repairers and heritage conservation professionals. Commercial maintenance teams also seek these components from us, especially our Roto collection. These products are manufactured to precise dimensional tolerances to ensure a perfect fit to your tilt and turn window.
