RL300B1 300B Series (250mm Span) 4-Arm Spider Fittings for Modern Facades
Category: Glass Spider Fittings / Mid-Size Series
Model: RL300B1 (300B Style)
Material: Stainless Steel 304 / 316
Product Overview
The RL300B1 is a distinct model within our "300B Series" family. While it shares the robust design language of our larger fittings, this specific model features a 250mm axial distance (hole-to-hole). This "Mid-Size" specification makes it the perfect engineering solution for projects where the heavy-duty 300mm spiders are oversized, but standard 200mm fittings lack the required reach.
Featuring a sleek X-Shape design, the RL300B1 provides a modern, minimalist aesthetic. It is widely favored by architects for shopping complexes, office partitions, and car showrooms in rapidly developing cities like Cairo (Egypt) and Doha (Qatar).
Cost-Efficiency: The 250mm span uses slightly less material than the fully heavy-duty RL3001 300mm model, offering a more competitive price point for budget-sensitive projects without compromising safety.
Optimized Geometry: As shown in the technical drawing, the arm design is streamlined (X-style) rather than the curved leg style, offering a sharper look for contemporary buildings.
Versatile Application: Ideal for glass panels of standard thickness (10mm - 15mm). It bridges the gap between light-duty and heavy-duty applications.
Global Application Scenarios
Office Partitions in Almaty (Kazakhstan): Used for internal glass walls where a 250mm span provides excellent stability for 12mm toughened glass.
Shopping Mall Facades in Bucharest (Romania): The mirror-polished finish resists urban pollution and adds a high-end touch to retail storefronts.
Airport Interiors in Doha (Qatar): Selected for its ability to handle indoor air pressure changes and high foot traffic vibration.
Elevator Enclosures: The compact 250mm size is perfect for panoramic elevator shafts where space is often limited.
Technical Specifications (Precision Casting)
Model: RL300B1
Axial Distance (C-C): 250mm (Please refer to the attached blueprint).
Center Hole: Ø37mm / Ø19mm (Standard mounting).
Arm Tip Width: 50mm.
Glass Hole Compatibility: Works with standard flat-head or countersunk glass routels.
Material:
SS304: Recommended for internal use or dry climates.
SS316: Essential for exterior use in humid or coastal regions.
Installation Note
The RL300B1 is designed to be mounted on a steel structure via a connector. Ensure your steel posts are pre-drilled according to the 250mm X-pattern. If you are replacing existing fittings, please measure the distance between the centers of your glass holes to confirm they match the 250mm spec.
FAQ (Frequently Asked Questions)
Q1: The series is called "300B", but the size is 250mm. Why?
A1: "300B" is the model family name indicating the design style (X-shape). However, the technical dimension for the RL300B1 is 250mm from hole center to hole center. Always check the drawing before ordering.
Q2: Is this spider strong enough for external use?
A2: Yes, absolutely. When cast in AISI 316 stainless steel, the RL300B1 is fully capable of withstanding external wind loads for standard-height buildings. For skyscrapers or typhoon zones, we recommend upgrading to our heavier RL3001 series.
Q3: Can you customize the surface finish?
A3: Yes. While Satin (Brushed) and Mirror (Polished) are standard, we can also provide PVD Gold or Matte Black finishes for luxury hotel projects in places like Dubai or Riyadh.
