Adjustable Spider Fitting Mounting Connector for Glass Facade Systems
The adjustable spider fitting mounting connector from AOYU provides a connection between architectural glass spider fittings and flat supporting structures. It combines a galvanized metal base with AISI 304 stainless steel fastening components to support accurate positioning during installation.
Unlike a glass point holder, this connector does not clamp the glass panel directly. Instead, it forms part of the mounting assembly that secures the spider fitting to its supporting surface.
Its compact cylindrical design also helps installers organize the connection hardware within point-supported glazing systems.
Adjustable Mounting Design
Three-Part Connector Assembly
The connector consists of three main components: a mounting base, an adjustment washer, and a fastening screw.
Each component serves a specific function. The base provides the mounting interface, while the screw connects the assembly to the compatible spider fitting. Meanwhile, the adjustment washer helps installers fine-tune the distance between the mounting components.
Together, these parts provide a practical solution for installing spider fittings on suitable flat supports.

Position Adjustment During Installation
Accurate positioning plays an important role in architectural glass installations. Therefore, AOYU designed this connector with an adjustment mechanism that helps installers align the spider fitting.
The supplied product specification lists an adjustment range of up to 10mm.
As a result, installers can make controlled positioning adjustments within the connector's specified range. However, they must still follow the approved installation drawing and structural design.
Compact Cylindrical Base
The connector features a cylindrical base and a layered adjustment assembly.
Additionally, the top fastening component includes a hexagonal socket for tool engagement, as shown in the product image.
This construction provides a compact mounting arrangement for compatible spider glazing hardware.
Galvanized Base and AISI 304 Stainless Steel Components
AOYU combines different materials within this connector to meet its intended mounting function.
The base uses galvanized metal, while the adjustment washer and fastening screw use AISI 304 stainless steel.
The galvanized surface provides a protective coating for the base. Meanwhile, stainless steel components offer corrosion resistance for many general architectural applications.
However, the installation environment can affect material selection. For example, coastal or highly corrosive locations may require additional protection or alternative specifications.

Flat Surface Mounting for Spider Fittings
This spider mounting connector is intended for installation on a suitable flat supporting surface.
First, installers should verify the mounting location and check the supporting structure against the approved project drawings.
Next, they can position the connector and assemble the compatible spider fitting using the specified fastening components.
The adjustment washer then helps fine-tune the connection position. Finally, installers must secure the assembly according to the required fastening procedure and engineering specifications.
Because structural glazing systems transfer loads through several connected components, a qualified engineer should verify the complete assembly before installation.
Applications in Architectural Glazing
Point-Supported Glass Facades
The connector can form part of a point-supported glass facade system that uses spider fittings to connect glass panels to structural supports.
It provides a mounting interface between the spider fitting and the supporting structure.

Commercial Glass Curtain Walls
Contractors can use compatible mounting connectors when installing spider-supported curtain wall assemblies.
Furthermore, the adjustable design helps accommodate positioning requirements within the approved connection arrangement.
Architectural Spider Glazing Systems
This connector also suits projects that require a compact support connection for spider glazing hardware.
Potential applications include commercial entrances, architectural glass walls, and other engineered point-supported glazing structures.
Spider Mounting Connector vs Glass Point Fixing
A spider mounting connector and a glass point fixing perform different functions.
A glass point fixing typically secures a glass panel at an individual fixing hole. In contrast, a spider mounting connector attaches the spider fitting to its supporting structure.
Therefore, installers should not substitute one component for the other.
Instead, they should select each fitting according to its position within the complete glazing system.

Frequently Asked Questions
What is an adjustable spider fitting mounting base used for?
An adjustable spider fitting mounting base connects a spider fitting to a suitable flat supporting structure. It provides a mounting interface for point-supported glass facades and architectural spider glazing systems.
How does the adjustable spider fitting connector work?
The connector combines a mounting base, an adjustment washer, and a fastening screw. Installers use the adjustment mechanism to fine-tune the spider fitting position. The product specification lists an adjustment range of up to 10mm.
What materials are used in the 1817-SM spider mounting base?
The 1817-SM features a galvanized metal mounting base and AISI 304 stainless steel adjustment washer and fastening screw. The base and fastening components use different materials, so the complete assembly should not be described as solid AISI 304 stainless steel.
Can the 1817-SM mounting base be installed on a flat surface?
Yes. AOYU designed this mounting connector for installation on a suitable flat supporting surface. Installers must verify the supporting structure, fastening method, and required connection dimensions against the approved project drawings.
How can I confirm whether the 1817-SM fits my spider fitting?
Check the required thread size, mounting base diameter, adjustment range, and connection geometry before ordering. AOYU can provide technical drawings for compatibility checks. A qualified engineer should also verify the complete structural glazing connection.
