250 Series 4-Arm Spider Fitting for Point-Supported Glass Curtain Wall
The 250 Series 4-arm spider fitting is a precision-cast stainless steel connector for point-supported glass curtain walls, canopies, skylights and glass elevators. Its cross-type 4-arm design distributes load evenly across the glass panel corners, delivering secure, structural-grade support with a clean, modern aesthetic.
Each arm is set at 90° from its neighbour, creating a balanced four-point fixing pattern that matches the corner geometry of rectangular glass panels. The central hub carries a threaded connection for routel fittings, so the spider can be paired with standard point-fixing hardware on site without special tooling. This makes the 250 Series a dependable, repeatable detail for facade contractors and glazing subcontractors working across multiple panel grids.

Installation & Usage
The spider fitting is fixed to the supporting structure through its back connection, and each glass corner is engaged with a routel fitting that threads into the hub. Fasteners should be tightened to the design values supplied in the project documentation, and gaskets or spacers checked for correct seating before final tightening. We recommend keeping the protective film on the polished faces during handling and cleaning the stainless surfaces after installation to remove fingerprints and construction residue.
Quality Assurance
Every spider fitting is 100% inspected before shipment for dimensional accuracy, surface finish and thread integrity. Material test certificates are available on request, and verified load-bearing data can be supplied to support structural design checks.
