250 Series 4-Arm Stainless Steel Spider Fitting, 25 mm Glass
The 250 series 4-arm spider fitting is the core connector of point-supported glass curtain wall systems. This version is specified for 25 mm glass, the heavier-duty connection used on exterior facades, high-rise lobbies, and large-area canopies where thicker laminated panels are required. Its four-arm cross design spreads structural loads evenly across adjacent panels while preserving the transparent appearance of the facade.
Investment cast in stainless steel with a 250 mm center-to-center arm spacing, it provides a robust, repeatable fixing detail at each panel corner. The balanced cross layout suits rectangular panel grids, giving glazing subcontractors a dependable component that lines up consistently across repeated facade bays.

Installation & Usage
The spider is fixed to its wall bracket or back connector through the central hub, and each glass corner is engaged with matching point-fixing hardware. Installers loosely assemble first, align the 25 mm thick panels to the drawn grid, and check that gaskets sit flat before final tightening. Protective film stays on polished faces during handling, and surfaces are cleaned once the elevation is complete.
Quality Assurance
Every 250 series spider fitting is 100% inspected before shipment for casting accuracy, thread integrity and surface finish. Material test certificates are available on request to support project specifications.
