Stainless Steel 250 Series 4-Arm Cross Spider Fitting for Glass Canopy
The precision-cast stainless steel 4-arm cross spider fitting is the standard nodal point fixing for point-supported glass canopies, skylights and structural glazing facades. The 250 series centre-to-centre distance matches the common corner grid of rectangular glass panels, so four adjacent panes meet cleanly at one node without oversized arms or cramped fixing holes.
Cast in SS304 or SS316 stainless steel, the spider distributes fixing forces evenly across the four glass corners and leaves the centre of the pane free of obstruction. Its cross shape suits both horizontal canopy roofs and vertical facade grids, which makes the 250 series a repeatable detail that glazing contractors can spec consistently across entrance canopies, atria and glass roofs.

Installation & Usage
The spider is fixed to the supporting structure through its centre connection, and each glass corner is engaged with a point-fixing fitting that seats into the arm hole with the correct gaskets. Fasteners are tightened to the design values in the project documentation, and gasket seating checked before the final pass. The protective film is kept on polished faces during handling and removed after cleaning.
Quality Assurance
Every spider fitting is 100% inspected before shipment for casting finish, arm alignment and thread condition. Material test certificates are available on request to support structural design checks.
