The Sloped Three Socket Tee is designed to connect two horizontal rails to a vertical upright on slopes between 11° and 30°. It is ideal for angled guardrails, ramps, and stair safety systems.
Please note: the two horizontal tubes must be separate pieces. They cannot pass through the fitting, as this would block the upright from being inserted vertically.
This fitting is available from stock and requires no machining. For the lower rail on a slope, use the matching Sloped Two Socket Cross (C58).
Typical applications: handrails, inclined safety railings, and barrier systems on gradients.
Assembly
Each key clamp is supplied with a set screw (Allen screw) for secure installation. An Allen key is the only tool required to tighten the tube firmly in the key clamp. Always use the correct Allen key size to prevent damage to the set screw and ensure proper tightening.
Quality & Standards
Our tube clamps are manufactured in accordance with BS EN 1562 and produced from high-quality malleable iron (grade KTH350-10). The tube clamps are finished with a hot-dip galvanised coating according to BS EN ISO 1461, providing excellent corrosion resistance and making them suitable for both indoor and outdoor use.
When properly tightened to a recommended torque of 39 Nm, the tube clamps create a strong and reliable mechanical connection. Load capacity depends on the specific fitting type, tube size and construction design.
