Stainless steel glass spider fittings
Product Overview
RL1501 150mm stainless steel 4 arm spider fitting is a classic four way glass spider designed for point fixed glass facade and canopy systems. It connects glass panels to steel structures or tension rod systems and provides four point support around each glass node, which improves safety and stability of the whole glass assembly.
This model belongs to the 150 series spider fittings with a 150 by 150 millimeter center distance. It is widely used in commercial plazas, shopping malls, office building entrances, glass canopies, glass skylights, glass elevators and panoramic corridors. In the international market, this type of product is commonly called spider fittings, glass spider fittings, 4 arm spider fitting or four way glass spider.
As a professional manufacturer, factory and wholesale supplier of spider fittings in China, we supply RL1501 four arm spider fittings in stainless steel 304 and 316, with satin or mirror finish. We support custom design according to project drawings and export regularly to Africa, the Middle East, Southeast Asia and many other regions.
Key Features And Advantages
Four arm design with balanced loading
RL1501 adopts a symmetrical four arm layout with a 150 x 150 mm grid. Each arm holds one glass fixing bolt and transfers loads from the glass to the main structure. Compared with two arm fittings, a 4 arm spider can distribute wind load, dead load and live load to four different points, which improves overall safety of the point fixed glass system.
Integrated precision casting body
The main body of the spider fitting is produced by precision investment casting. The four arms and central hub are cast as one piece, which avoids weak points at welded joints and offers higher strength and longer service life. The smooth curvature between arms and center hub also provides good stress distribution and an elegant architectural appearance.
High quality stainless steel
Standard material is stainless steel 304, which is suitable for most indoor and outdoor applications. For coastal projects, chemical plants or other aggressive environments, we recommend stainless steel 316 or 316L to achieve better corrosion resistance. All matching bolts, nuts, sleeves and washers can be supplied in the same material, so the complete glass spider fittings system performs consistently.
Attractive surface finish
Both satin (brushed) and mirror polished finishes are available. Satin finish is widely used in commercial buildings because of its low maintenance requirement and modern look. Mirror finish shows a strong metallic gloss and is often selected for hotel lobbies, high grade office buildings and observation elevators where visual impact is important.
Flexible connection to different structures
RL1501 four arm spider fittings can be connected to steel posts, H beams, round tubes, trusses, reinforced concrete structures with embedded plates, or tension rod and cable systems. With the help of different adapters and brackets, the same spider model can be used on flat facades, corners, slopes and curved surfaces.
Factory direct supply and custom service
We are not only a supplier but also a spider fittings manufacturer and factory. Besides standard RL1501 150 mm four arm spider fittings, we can produce customized versions with different center distances, hole diameters, arm shapes or special angles. OEM and ODM orders are welcome. For distributors and project contractors, we offer competitive wholesale prices, stable lead time and professional technical support.
Technical Data

Type: 4 arm spider fitting, four way glass spider
Center distance: 150 mm x 150 mm
Center hub diameter: about 45 mm
Arm head diameter: about 40 mm
Glass fixing hole matching diameter: about 16.5 mm
Arm thickness: around 14.5–20.5 mm depending on the position
Material: stainless steel 304, stainless steel 316 or 316L
Surface finish: satin (brushed) or mirror polished
Suitable glass: tempered glass, laminated glass, insulating glass with drilled holes
Typical glass thickness: 10–25 mm depending on design
Application: glass canopy, glass skylight, glass curtain wall, glass elevator shaft, glass corridor, glass balustrade and handrail
Typical Applications
Commercial plaza glass canopy
At the main entrance of shopping malls and commercial plazas, RL1501 spider fittings are used to support glass canopies together with tension rods or steel beams. The stainless steel spider fittings ensure a safe connection between glass and structure while keeping the canopy visually light and transparent.
Skylights and roof glazing
Large skylights on office buildings, airports, railway stations and exhibition centers often use point fixed glass systems. RL1501 4 arm spider fittings arranged in a 150 x 150 grid distribute the weight of glass panels and resist wind load. With proper design of slopes and gutters, the system can provide excellent daylighting and reliable waterproof performance.
Glass curtain wall and facade
When used on glass facades, spider fittings help create a frameless appearance with minimal visible hardware. RL1501 is suitable for medium size facades with regular grid, and can be combined with vertical steel posts, cable walls or trussed structures. The clean lines and small visible area of the four arm spider are ideal for modern architecture.
Glass elevator and observation shaft
For glass observation elevators in shopping malls, hotels and office buildings, RL1501 stainless steel spider fittings can be used around the shaft to fix vertical glass panels. The fittings provide sufficient structural strength while keeping the view open, giving passengers a panoramic experience.
Pedestrian bridges and glass corridors
In glass corridors, sky bridges and viewing platforms, point fixed glass with spider fittings is widely used. RL1501 150mm four arm spider can connect glass side walls, roof panels or balustrades to the supporting steel frame, offering transparency and modern aesthetic at the same time.
Installation Guidelines And Notes
Design stage
A qualified structural engineer should select appropriate glass thickness, spider fitting model and fixing details according to local codes, design wind pressure, building height and span. RL1501 4 arm spider fitting is suitable for many projects, but some large span or high rise facades may require other types or additional reinforcement.
Installation steps (summary)
Check all components including spiders, routels, bolts and gaskets. Make sure surfaces are clean and free from damage.
Fix the RL1501 spider fittings on the steel structure or adapter plates according to drawings. Align the center lines and angles carefully.
Lift the pre drilled glass panel into position, insert the routel bolts through the glass holes and connect them to the spider arms.
Tighten all bolts evenly with a torque wrench. Do not over tighten to avoid excessive local stress on the glass.
After installing all glass panels, check joint gaps, sealant condition and alignment of the whole facade or canopy.
Important notes
Glass edges and holes must be processed by qualified glass factories and comply with relevant standards.
All contact surfaces between glass and metal should be separated by appropriate nylon or rubber gaskets.
In coastal or industrial environments, using 316 stainless steel spider fittings is strongly recommended.
Periodic inspection should be carried out. If any bolts are loose or any component shows serious corrosion or deformation, replace them immediately.
