300 Series 3-Arm Stainless Steel Spider Fitting for Point-Supported Glass Curtain Wall
The 300 series 3-arm spider fitting is the core connector of point-supported glass curtain wall systems. Its three-arm 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 three-arm configuration is typically used at internal corners and T-junctions of the panel grid, where three glass panels meet at one point. Precision investment casting in stainless steel gives the hub and arms a smooth, consistent form, so facade contractors receive a repeatable fixing detail across a large elevation.
Key Features
- Material: SS304 / SS316 stainless steel, precision investment cast
- Design: 3-arm spider, 300mm center distance
- Function: Distributes structural loads evenly across three adjacent glass panels
- Finish: Mirror polished or satin brushed, uniform and clean
- Quality: 100% inspected before shipment; material test certificates available on request
Specifications
- Series: 300 Series 3-arm spider fitting
- Center distance: 300 mm
- Configuration: Three-arm layout for corner and T-junction points
- Material options: SS304 or SS316 stainless steel
- Surface finish: Mirror polished or satin brushed
Installation & Usage
The spider is fixed to its supporting bracket through the central hub, and each of the three glass corners is engaged with matching point-fixing hardware. Installers loosely position the fitting, align the panel corners 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.
