250 Series Stainless Steel Spider Fittings
250 Series Stainless Steel Spider Fittings
SSHW 250 series stainless steel spider fittings for glass curtain walls and canopies, with 304/316/2205 options and multiple finishes, suitable for coastal salt spray projects.
250 Series Stainless Steel Spider Fittings (1/2/3/4 Way)
The SSHW 250 series stainless steel spider fittings are designed for point-supported connections on glass façades, canopies, and balustrades. With 125 / 250 mm arm lengths and 1/2/3/4 way configurations, the series allows designers and façade contractors to keep one hole pattern while arranging different glass grid layouts.
This page focuses on models 250B1, 250B2, 250B3, 250B4, 250B11, and 250B21. All share a standard 26 mm glass hole and matching routel system, making them suitable for many small- to medium-span glass façades and canopies. With suitable material grades, they can be configured for coastal salt spray, tropical rainfall, desert sand, and cold climate outdoor conditions.
1. Models & Dimensions
All models are based on a 26 mm glass fixing hole with a 40 mm outer cover plate, so drilling and accessory selection can be unified across a project.
| Model | Arms | Nominal arm length* (mm) | Approx. overall size (mm) | Glass hole size (mm) | Typical use |
|---------|------|--------------------------|----------------------------|----------------------------------------|------------------------------------------------------|
| 250B1 | 1 | 125 | ~125 × 125 | Ø26 through hole with Ø40 cover | End-point edge finishing |
| 250B11 | 1 | 125 | ~125 | Ø26 through hole with Ø40 cover | Vertical single-point stiffening |
| 250B2 | 2 | 2 × 125 (V-shape) | Span ~250, height ~125 | Ø26 through hole with Ø40 cover | Edge or intermediate V-shaped joints |
| 250B21 | 2 | 2 × 125 (inline) | Length ~250 | Ø26 through hole with Ø40 cover | Vertical inline joint arrangements |
| 250B3 | 3 | 3 × 250 | ~250 × 250 | Ø26 through hole with Ø40 cover | Corners or three-direction transition joints |
| 250B4 | 4 | 4 × 250 | ~250 × 250 | Ø26 through hole with Ø40 cover | Central cross joints in regular grids |
\*Nominal arm length is the design distance from each routel center to the main fixing hole; always verify against project shop drawings.
Note: Dimensions above are based on SSHW standard drawings. For compatibility with existing systems or special spacings, customized versions can be evaluated on a project basis.
2. Key Features
Clear glass spider bracket geometry
Symmetrical arms and unified hole sizes support standardized fabrication and quick on-site alignment, ideal for typical façade and canopy grids.
Flexible combinations within one 250 series spider fittings family
From 1-way to 4-way arms, center spans, edge spans, and end terminations can all be handled with the same design language, reducing part variety on site.
High compatibility with glass spider routel assemblies
Matching routels, gaskets, and cover caps are available as a complete kit, helping minimize inventory and simplifying procurement and maintenance.
4-way glass spider bracket for central joints
Model 250B4 is suited to cross-shaped joints, distributing glass loads evenly to the support structure and reducing local stress concentration.
Suitable for frameless glass facade spiders aesthetics
Streamlined profiles with polished chamfers provide both strength and a visually light appearance, ideal for clean, highly transparent façades.
3. Materials & Surface Finishes
All 250 series components are cast and machined from SUS304, SUS316, or 2205 duplex stainless steel to meet a wide range of point-fixed glass hardware requirements:
SUS304 – For interior railings, atrium glazing below weather exposure, and low-corrosion areas.
SUS316 – Recommended for most exterior applications in standard urban or mild coastal conditions.
2205 duplex – For highly corrosive environments with strong salt spray or poolside chlorides, subject to corrosion-category assessment.
Available finishes:
Satin – Brushed appearance that reduces visible fingerprints, suitable for high-traffic zones.
Mirror – High reflectivity to match premium façade designs.
PVD (black, champagne gold, etc.) – Provides color options and a distinct surface tone; corrosion performance is still governed by the base steel grade.
General guidance on selecting stainless steels for exterior building use can be found in the British Stainless Steel Association article and should be combined with project-specific code and engineering requirements.
4. Glass Compatibility & Typical Applications
Suitable for tempered, laminated, and insulating glass units.
Glass thickness and build-up must be defined by structural design and local codes; SSHW can provide typical recommendations on request.
Point-supported glass curtain walls (main and side elevations)
Glass canopies and awnings
Balcony and stair glass balustrades, atrium guards
Lobby skylights and entrance glazing in office or commercial buildings

SSHW Spider Fittings Installation & Adjustment Videos.
5. Installation Methods & Accessories
The 250 series stainless steel spider brackets can be fixed to posts, glass fins, or steel structures:
Supports top mount, side mount, and fin-mounted configurations.
The central fixing hole is designed to work with welded plates or steel beams/posts; final bolt grade and thickness are defined by the structural engineer.
Limited adjustment of arm angle and glass center spacing on site helps absorb construction tolerances.
Accessories and system integration:
Matching routels, posts, handrail tubes, cover caps, nylon washers, and EPDM seals are available to form a complete point-supported glass system.

7. Quality Control & Testing Support
Material & dimensional inspection
Chemical composition, key dimensions, and surface finish are sampled before shipment. Material certificates and dimensional check reports can be supplied on request.
Corrosion and salt spray tests
For environments such as coastal salt spray or tropical rainfall, third-party salt spray or corrosion test summaries can be provided where available, with full details contained in the official reports.
Structural and impact tests
For guardrail or curtain wall applications where specific load or impact performance must be demonstrated, mock-up testing can be arranged on a project basis, with results provided for engineering review.
Additional insights into installation and on-site adjustment can be found in the SSHW YouTube playlist linked above.

9. FAQ
Q1: Which material grade is recommended for 250 series fittings in coastal or poolside environments?
A: SUS304 is typically used indoors or in low-corrosion areas. For most exterior conditions, SUS316 is recommended, while 2205 duplex is often preferred for strong salt spray or poolside chloride exposure. Final selection must follow local codes and corrosion-category assessment by the design team.
Q2: What glass thickness and hole size should be used with the 250 series?
A: The standard glass hole for this series is Ø26 mm with a Ø40 cover plate, which simplifies processing. Glass thickness and build-up must be determined by structural calculations and local regulations; SSHW can offer reference values on request but does not replace structural design.
Q3: Can 1/2/3/4 way models be mixed on the same façade?
A: Yes. A common approach is to use 250B4 at central grid joints, 250B3 or 250B2 at edges and corners, and 250B1 / 250B11 or 250B21 at end conditions. The final configuration should be defined by the façade engineer according to panel layout and structural behavior.
Q4: Is it possible to customize arm length, spacing, or special finish colors?
A: Subject to structural and manufacturing feasibility, customized arm lengths, center spacings, or special PVD colors can be evaluated. Minimum order quantities and lead times for customized items are confirmed per project.
Q5: What documentation can SSHW provide to support quotations and design?
A: Once models and quantities are confirmed, SSHW can supply product dimension drawings, installation sketches, material statements, and, where available, relevant test report summaries. Full structural calculations and detailed construction drawings remain the responsibility of the project design and construction teams.
