120 Series 2-Arm Stainless Steel Spider Fitting for Point-Supported Glass Curtain Wall
The 120 series 2-arm spider fitting is the core connector of point-supported glass curtain wall systems. Its two-arm design distributes structural loads evenly across adjacent glass panels, keeping the facade visually lightweight while providing reliable holding strength. Investment cast in SS304 or SS316 stainless steel, it is specified where a line of glass corners meets a shared structural node.
The two-arm (90°) layout suits panel edge junctions and straight runs in the glazing grid, and the threaded centre connection pairs the spider with standard routel fittings. The smaller 120mm centre distance makes it a good fit for tighter facade modules, canopies and structural glazing details, while the satin or mirror finish keeps every node reading the same across the elevation.

Installation & Usage
The spider is fixed to the supporting structure through its back connection, and each engaged glass corner is fitted with a routel that threads into the arm. Panels are aligned to the design grid, then fasteners are finally tightened with gaskets checked for even seating. Polished faces keep their protective film during installation, and the stainless surfaces are cleaned at handover.
