This base flange key clamp is designed to support a vertical post and includes an integrated toeboard mount. The side flanges allow a kick board to be directly attached, making it ideal for guardrail and balustrade systems in industrial or public safety settings.
The side plates feature slotted holes for lateral adjustability during installation. The base can be fixed using mechanical or chemical anchors. Constructed from hot-dip galvanised steel for long-lasting outdoor use.
Typical applications: safety railings with toe boards, edge protection, balustrades on platforms or walkways.
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.
