200 Series 3-Arm Stainless Steel Spider Fitting for Point-Supported Glass Curtain Wall

200 Series 3-Arm Stainless Steel Spider Fitting for Point-Supported Glass Curtain Wall

The 200 series 3-arm spider fitting is the core connector of point-supported glass curtain wall systems. Its 3-arm design distributes structural loads evenly across adjacent glass panels, keeping the facade visually lightweight while providing reliable holding strength.

The three-arm arrangement is typically specified at internal panel intersections and edge nodes, where one hub picks up three adjacent glass corners, and the 200mm center distance matches the panel modules common on commercial curtain wall projects. Precision investment casting gives the body uniform wall sections and a clean, dense surface, and the central hub bolts to a supporting rosette or spider adapter so the whole node can be aligned on site before final fixing. This makes the 200 series a dependable, repeatable detail for facade contractors and glazing subcontractors working across standard panel grids.

• Center distance: 200mm between arm fixing points
• Material options: SS304 or SS316 stainless steel
• Casting: Precision investment cast body for consistent geometry
• Finish options: Mirror polished or satin brushed

Installation & Usage

The spider is bolted to the supporting structure through its central hub, and each arm end locates a glass corner through the point-fixing hole. Protective shims or gaskets between the arm and the glass edge should be checked for even seating before the fixings are tightened, and the panel grid should be aligned to the design layout first. Keep protective film on polished faces during handling and clean the stainless surfaces after installation.

Quality Assurance

Every spider fitting is 100% inspected before shipment for dimensional accuracy, surface finish and fixing-hole integrity. Material test certificates are available on request to support project specifications and structural review.

Applications
