AISI 304 Y-Type Three Arm Spider Fitting 200mm for Glass Facades

The three arm spider fitting from AOYU features a Y-shaped design with three glass fixing positions around a central mounting point. Made from AISI 304 stainless steel, this 200mm fitting supports point-fixed glazing connections in architectural glass structures.

Its three-arm configuration allows installers to connect glass panels at three separate fixing positions using compatible glass holders. Therefore, it offers a practical solution for glass facades, curtain walls, canopies, and other engineered glazing projects.

Y-Type Three Arm Spider Fitting Design

Unlike single-arm or two-arm spider fittings, the Y-type design provides three connection arms extending from one central body.

Each arm ends in a circular mounting position for a compatible glass holder. Meanwhile, the central opening allows the fitting to connect to an appropriately designed supporting structure.

This configuration makes the fitting suitable for glazing layouts that require three point-fixing connections around a shared structural support.

Three Glass Fixing Positions

The three-arm arrangement provides several practical features:

• Three separate glass connection positions
• Y-shaped layout for multi-directional glazing connections
• Central mounting opening for structural attachment
• Circular arm ends for compatible glass fixing accessories
• A polished stainless steel surface for exposed architectural applications

AISI 304 Stainless Steel Construction

AOYU manufactures this Y-type spider fitting from AISI 304 stainless steel.

The material provides corrosion resistance for many architectural applications. In addition, the polished stainless steel finish creates a clean metallic appearance that complements modern glass facades.

The fitting is supplied with a PSS polished finish, making it suitable for projects where visible hardware forms part of the architectural design.

Material selection should always consider the installation environment, particularly in coastal or highly corrosive locations.

200mm Three Arm Spider Fitting Dimensions

The fitting has a specified 200mm center-to-center dimension.

Its compact central body connects the three arms, while the circular ends provide mounting locations for the glass holders.

The supplied technical drawing identifies the following dimensions:

• Center-to-center dimension: 200mm
• Outer diameter of glass connection ends: 45mm
• Thickness of glass connection ends: 11mm
• Central mounting body thickness: 16mm

For accurate fabrication, customers should review the complete dimensional drawing before preparing glass panels or supporting structures.

Important: Fx and Fy values apply to each individual arm. They do not represent the verified load capacity of a complete installed glazing system. Final suitability depends on the supporting structure, fasteners, glass specification, installation details, and structural calculations.

Compatible 1816 Glass Holder

The three arm spider fitting is compatible with the 1816 glass holder, which is available separately.

Each of the three circular arm ends provides a connection position for a compatible holder. As a result, the spider fitting and glass holders can form part of a point-supported glazing assembly.

Customers should confirm the required glass thickness, hole dimensions, fasteners, and accessory configuration before ordering.

Applications of Y-Type Glass Spider Fittings

Glass Facades and Curtain Walls

The three-arm design can connect multiple glass fixing points around a central structural support. This makes it useful in selected glass facade and point-supported curtain wall layouts.

Glass Canopies and Awnings

The fitting can also form part of engineered glass canopy and awning systems where a three-position connection is required.

Architectural Glass Structures

Other potential applications include glass shopfronts, atriums, and custom architectural glazing assemblies, subject to project-specific structural design.

Installation and Structural Considerations

Before installation, confirm that the supporting structure and glass fixing accessories are compatible with the selected spider fitting.

The installer should check the mounting position, connection dimensions, glass preparation, and fastener specifications against approved project drawings.

Furthermore, a qualified structural professional should verify the complete system against applicable design loads and local building requirements.
