The Black 180° Glass Stiffener is a professional-grade connector engineered for joining two glass panels in a straight line while maintaining precise alignment and rigidity. Constructed from marine-grade 316 stainless steel and coated in matte black, it ensures long-term durability and visual harmony across the balustrade system. This inline stiffener accommodates glass panels between 10mm and 21.5mm thick, making it suitable for a wide range of frameless glass applications including staircases, balconies, and terrace railings. The fitting’s internal compression design provides superior load transfer and vibration resistance, reducing flexing under environmental forces. Installation is straightforward, using standard fixings and alignment jigs. The discreet black finish complements contemporary architectural designs, offering both strength and refinement. It’s the ideal solution for projects requiring seamless structural continuity with minimal aesthetic interruption.

All components are designed to suit glass panels between 10mm and 21.5mm thick. This includes monolithic, toughened, and laminated glass, depending on the installation’s structural requirements.
Yes. Every part is manufactured from marine-grade 316 stainless steel, offering excellent resistance to corrosion, salt exposure, and UV degradation. Both the Satin and Black powder-coated finishes are tested for outdoor use.
Absolutely. The system meets the performance and durability standards required for domestic, public, and light commercial installations, including balconies, terraces, and stair balustrades.
No specialist tools are required. A standard Allen key set, torque wrench, level, and drill are sufficient. Always follow torque specifications provided in the installation guide to prevent over-tightening.
Clean regularly with warm soapy water and a microfiber cloth. Avoid harsh chemicals or abrasive pads. For coastal locations, a periodic rinse with fresh water helps maintain surface integrity and appearance.
We recommend using components from the same hardware collection (Black or Satin) to ensure proper fit and load performance. Mixing brands may affect alignment and warranty coverage.
Typically, two spigots per 1,000 mm panel are recommended for standard installations. For taller or wind-exposed balustrades, consult engineering guidelines or local building codes.
Only the finish varies — both use identical 316-grade stainless steel construction. Satin provides a brushed metallic look, while Black features a powder-coated matte surface for a modern aesthetic.
Yes. The adjustable spigot and stiffener designs allow for fine alignment after the
glass is in place. You can slightly reposition or level the panels by loosening the clamp and re-torquing it using a calibrated wrench to ensure correct
positioning and even load distribution.
Yes. When installed according to The Outdoor Look guidelines, all fittings and systems meet or exceed relevant UK standards for balustrade load performance and safety.
Each full kit includes spigots, cover plates, and accessories required for installation. Fixing bolts are not included and need to be purchased separately. The kit is designed for compatibility with 10–21.5mm frameless glass panels.
No sealing is required for the fittings themselves. However, silicone edge protection may be used between the glass and stainless-steel hardware in high-exposure environments for added vibration damping.
