220 Series 4-Arm Stainless Steel Spider Fitting for Point-Supported Glass Curtain Wall

220 Series 4-Arm Stainless Steel Spider Fitting for Point-Supported Glass Curtain Wall

The 220 series 4-arm spider fitting is the core connector of point-supported glass curtain wall systems. Its four-arm cross design distributes structural loads evenly across adjacent glass panels, keeping the facade visually lightweight while providing reliable holding strength.

Built on a 220 mm center distance, this cross configuration sits between the compact and wider spider ranges, suiting medium panel grids where the arm spacing needs to match a finer facade module. Precision investment casting in stainless steel gives the hub and arms a smooth, consistent form, so contractors receive a repeatable fixing detail that lines the panel grid up cleanly across repeated bays.

Key Features

• Material: SS304 / SS316 stainless steel, precision investment cast
• Design: 4-arm cross spider, 220mm center distance
• Function: Spreads structural loads evenly across 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: 220 Series 4-arm cross spider
• Center distance: 220 mm
• Configuration: Four arms around the central hub
• 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 glass corner is engaged with matching point-fixing hardware. Installers loosely position the first bay, 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 220 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.
