The Railing Base Flange is a heavy-duty key clamp designed to provide a strong, structural fixing for vertical posts on guardrails and safety barriers. Two set screws ensure a secure and rigid connection to the tube.
For maximum strength, align the fixing bolts with the direction of the applied load. Suitable for mechanical or chemical anchors. The tube can not pass through the base.
Typical applications: guardrails, balustrades, access barriers, and other safety-critical structures.
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.
