300 Series 2-Arm Stainless Steel Spider Fitting for Point-Supported Glass Curtain Wall
The 300 series 2-arm spider fitting is the core connector of point-supported glass curtain wall systems. Its two-arm (90° or 180°) design distributes structural loads evenly across adjacent glass panels, keeping the facade visually lightweight while providing reliable holding strength.
Built on a 300 mm center distance, this two-arm configuration is used along panel edges and at vertical or horizontal joints where only two panels meet. Precision investment casting in stainless steel gives the hub and arms a smooth, consistent form, so contractors receive a repeatable edge detail that lines up cleanly across repeated facade bays.
Key Features
- Material: SS304 / SS316 stainless steel, precision investment cast
- Design: 2-arm (90° or 180°), 300mm center distance
- Function: Distributes structural loads evenly across two adjacent glass panels

- Quality: 100% inspected before shipment; material test certificates available on request
Specifications
- Series: 300 Series 2-arm spider fitting
- Center distance: 300 mm
- Configuration: Two arms at 90° or 180°
- Material options: SS304 or SS316 stainless steel

Installation & Usage
The spider is fixed to its supporting bracket through the central hub, and the two glass corners are engaged with matching point-fixing hardware. Installers loosely position the fitting, align the panel edges to the drawn grid, and check gasket seating before final tightening. Protective film stays on polished faces during handling, and stainless surfaces are cleaned once the elevation is complete.
Quality Assurance
Every 300 series spider fitting is 100% inspected before shipment for casting soundness, thread integrity and surface finish. Material test certificates are available on request to support project specifications.
Applications
- Point-supported glass curtain walls
