The Black 90° Glass Stiffener is a precision-engineered corner connector that reinforces the junction between two glass panels at a right angle. Manufactured from 316-grade stainless steel and finished in matte black, this stiffener combines strength, precision, and contemporary style. It’s compatible with glass thicknesses from 10mm to 21.5mm, providing reliable alignment and load distribution across the joint. The concealed fastening design maintains the clean, frameless appearance of modern balustrade systems while ensuring exceptional structural integrity. Ideal for stair landings, L-shaped balconies, and corner glass installations, it withstands external forces including wind load and vibration. The product’s UV- and corrosion-resistant coating guarantees long service life with minimal maintenance. A trusted component in professional installations where visual uniformity and engineering reliability are equally essential.

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.
