300 Series K-Arm Stainless Steel Spider Fitting for Point-Supported Glass Curtain Wall
The 300 series K-arm spider fitting is the core connector of point-supported glass curtain wall systems. Its K-claw design distributes structural loads evenly across adjacent glass panels, keeping the facade visually lightweight while providing reliable holding strength through threaded point connections at each arm tip.
Precision investment cast in stainless steel, the K-arm body offers a clean casting finish and a consistent arm geometry that repeats panel after panel on the glass grid. The 300mm center distance matches standard panel corner layouts, and each hub accepts our range of routel fittings, so contractors can build the whole point-fixing detail from one coordinated hardware system. The result is a transparent facade that shows the architecture rather than the fixings.

Installation & Usage
The spider is fixed to the supporting structure through its back connection, and each glass corner is engaged with a routel fitting that threads into the arm hub. The panel grid is aligned first, fasteners are drawn up evenly, and only then brought to the project-specified tightening. Gaskets at the glass holes should be checked for even seating, and the polished faces kept film-protected until the facade is cleaned.
Quality Assurance
Every spider fitting is 100% inspected before shipment for casting quality, thread integrity and surface finish. Material test certificates are available on request to support project specifications.
Applications
- Point-supported glass curtain walls
- Glass canopies and skylights
- Structural glazing and glass balustrade systems
- Atriums, shopfronts and entrance glazing
Customization & OEM
Custom center distances, arm lengths and finishes are available. Wholesale and OEM orders are welcome. Send us your panel layout to request a quote, and we can supply matching routels, bolts and brackets so the whole point-supported facade comes from one consistent range.
