This acute elbow key clamp connects a sloped top rail to a vertical post on descending surfaces with a pitch between 11° and 30°. It offsets the tube angle from a standard 90° connection, resulting in a total angle between approximately 60° and 79°.
Ideal for sloped handrail terminations on staircases or ramps. A practical alternative to bending tube, offering a neat finish and easy installation.
Typical applications: sloped handrail ends, downward safety rail corners, angled stair transitions.
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.
