Product Introduction & Architectural Aesthetic
The RL L220B2 single arm glass fin spider fitting is a premier structural solution engineered specifically for modern point-supported glass fin wall systems. Designed to harmonize heavy-duty mechanical capacity with minimalistic architectural aesthetics, this single-arm connector effortlessly transfers external wind and dead loads from the exterior glass facade to the structural glass fin behind it. By eliminating bulky metal framing, it allows architects to design building envelopes with unparalleled levels of transparency and natural daylighting.
Fabricated utilizing advanced precision investment casting, the RL L220B2 is available in top-tier SUS304 and SUS316 grades. It offers superior durability and high tensile strength under cyclic loading. To achieve a perfectly coordinated curtain wall assembly, it is designed to work in synergy with our specialized Spider Routel units and high-tensile Fixing Clamp / Glass Clamp ranges, providing structural stability and peace of mind for design professionals worldwide.

Applications & Professional Installation Guide
This heavy-duty spider fittings setup is perfect for double-height commercial lobbies, glass vestibules, shopping mall canopies, and high-end storefronts.
Step-by-Step Installation Procedure:
Glass Fin Marking & Drilling: Precisely mark the dual anchoring holes on the structural glass fin according to the structural calculations. Utilize diamond-tipped core drills to guarantee perfectly smooth inner bore surfaces.
Gasket Placement: Place high-density, UV-resistant EPDM or nylon isolator washers between the stainless steel plates and the glass surfaces. Metal-to-glass contact must be strictly avoided to eliminate localized stresses.
Inserting the Sleeve & Bolt: Align the RL L220B2 bracket over the glass fin hole. Insert the high-strength bushing (Φ 15.5 mm sleeve) followed by the locking bolts. Tighten progressively with a calibrated torque wrench to 15-18 N·m.
Connecting the Routel: Assemble the corresponding point-support glass routel into the Φ 26 mm eyelet. Take advantage of the integrated clearance to align the outer glass panels perfectly.
100% Virgin Refining Material: While cheap market alternatives utilize low-cost recycled scrap metal prone to internal shrinkage and structural voids, we exclusively cast our fittings using premium AOD-refined stainless steel ingots. This delivers exceptionally high yield strength and zero risk of brittle failure.
Architectural Grade Surface Polishing: Every fitting undergoes a rigorous multi-stage mechanical and manual polishing process, achieving a flawless Mirror Polish (Ra < 0.2 $\mu$m) or elegant Satin Finish. The ultra-smooth exterior prevents dirt and atmospheric dust accumulation in arid or windy climates.
In a newly built premium rooftop restaurant overlooking Ala-Too Square in Bishkek, Kyrgyzstan, the architectural design demanded a completely transparent facade. However, Bishkek's continental climate brings extreme seasonal temperature swings, ranging from -25°C in deep winter to over +38°C in high summer.
The project's senior manager shared his satisfaction during a routine quality review:
"We were highly concerned that the immense dry freeze in Bishkek would stress our point-supported glass fin connections. We chose the RL L220B2 single arm fin spiders alongside heavy-duty Glass spigots from your line. After enduring two full cycles of extreme summer-to-winter transitions, our engineering team confirmed zero stress fractures, perfect joint alignment, and absolutely no surface corrosion. The peace of mind this brings is invaluable."
Case Study 2: Corporate Headquarters Lobby in the Southern Business District of Bishkek
A magnificent 15-meter-high glazed entrance lobby for a multinational corporate headquarters in Bishkek's elite southern district required a robust, wind-resistant glazing solution. Due to the proximity of the Tian Shan mountain range, the facade has to endure frequent down-slope mountain wind gusts and minor seismic tremors.
The lead structural engineer of the construction consortium noted:
"To resist high-velocity wind loads, our structural calculations demanded a highly reliable fin-to-facade connector. The RL L220B2 outshone competitor samples due to its robust 15mm thick earplates and precise casting dimensions. Working alongside a stabilizing Tension rods / Stainless Steel Rod net, the glass fin wall stands completely rigid against mountain winds. The local construction crew was also extremely pleased with how easily the tolerances aligned during onsite installation."
Structured Schema FAQ
Q1: Is the RL L220B2 spider fitting suitable for highly corrosive or extreme cold climates?
A: Absolutely. For regions like Bishkek, Kyrgyzstan, which experience extremely low winter temperatures and dry, dusty winds, we highly recommend our SUS316 grade. SUS316 features a 2-3% molybdenum content that significantly enhances resistance to pitting corrosion and prevents thermal-stress micro-cracking.
Q2: What is the main structural difference between a standard spider fitting and a fin spider?
A: Standard spider fittings are designed to mount directly onto steel hollow sections, columns, or pipes via a central mounting bolt. In contrast, the RL L220B2 is a "fin spider" featuring a dual-clamp U-channel base specifically designed to wrap around and securely pinch a structural glass rib (fin) using high-tensile through-bolts.
Q3: What torque value should be applied during the installation of this glass fin connector?
A: For our Φ 15.5 mm outer sleeve assemblies, we recommend a locking torque value between 15 N·m and 18 N·m. Always ensure the high-durability EPDM/Nylon isolators are correctly positioned to prevent direct contact between the stainless steel cast plates and the structural glass fin.
