Types by Number of Arms (Fitting Configurations)

​

Spider fittings are classified by the number of arms or legs they use to connect glass panes:

 

• Single-Arm Spider Fittings: Feature a single arm and are used at the edges or corners of a single glass panel.

• Double-Arm Spider Fittings: Feature two arms designed to connect two adjacent glass panels in a line or corner configuration​.

• Three-Arm Spider Fittings: Feature three arms used to join three glass panels together, often at T - junctions.

• Four-Arm Spider Fittings: Feature four extending arms that connect four separate glass panels at a single point (the most common type for large glass facades). ​

​

Types by Supporting Structure

 

Spider glazing systems are also categorized by the structural element that carries the dead load and wind pressure of the glass.

​

• Spider Glazing with Glass Fins: Uses vertical, high-strength toughened or laminated glass fins (typically 10mm to 19mm thick) instead of metal columns to provide transparent structural support.​

• Spider Glazing Using Stainless Steel or Mild Steel (MS) Trusses / Frames:​ Uses slender vertical and horizontal steel pipes, columns, or I - beams to supportive spider hardware and large glass elevations.

• Cable-Supported (Tension Rod/Net) Spider Glazing: Uses pre-tensioned stainless steel cables or suspension rods in a net geometry to hold the glass with a nearly invisible, lightweight framework. 

​

Spider​ Fittings come in 304 (standard grade) & 316 (marine grade) Stainless Steel.

 

The standard size is 250mm other on request.
