250 Series 4-Arm Stainless Steel Spider Fitting, 18 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 18 mm glass, matching the smaller panel connection commonly used on interior facades, atriums, and lightweight canopies. Its four-arm cross design distributes structural loads evenly across adjacent glass panels, keeping the facade visually lightweight while providing reliable holding strength.
Investment cast in stainless steel and built on a 250 mm center-to-center arm spacing, it delivers a clean, consistent fixing point at every panel corner. The balanced cross layout lines up with rectangular panel grids, giving glazing subcontractors a repeatable detail across repeated internal and semi-external elevations.

Installation & Usage
The spider is fixed to its supporting bracket through the central hub, and each glass corner is engaged with matching point-fixing hardware. Installers loosely assemble the first bay, align the 18 mm panels to the drawn grid, and confirm gasket seating before final tightening. Protective film is kept on polished faces during handling, and the stainless 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.
