The Long Tee key clamp, also known as Three Socket Tee, is designed to create a strong 90° connection between two tubes of 26.9 mm diameter. Unlike the Short Tee, this fitting allows a join in the horizontal tube, ideal when two rails need to meet within the clamp and be secured using internal socket set screws.
Commonly used for connecting a top rail to a vertical upright in handrail and guardrail systems, the Long Tee provides additional flexibility in design. It can accommodate either a single through tube or two separate tubes joined inside the top of the 'T'.
Manufactured from galvanised steel for durability and corrosion resistance, this fitting is suitable for both indoor and outdoor use.
Typical applications: safety handrails, guardrails, industrial barriers, and tubular frameworks where a rail join is needed.
Assembly
The included set screw (Allen screw) makes assembly easy. An Allen key is the only tool needed to firmly secure the tubes in the tubeclamps. Please insure the right size allen key, an incorrect size can potentially damage the set screw.
Quality
Our key clamps have been manufactured according to strict specifications. The fittings are made from malleable iron (according to BS EN 1562) and are usually delivered in a hot dip galvanised finish (BS EN ISO 141) in order to combat corrosion and have a longer lasting product. Because of the galvanised finish this fitting is perfectly suitable for outdoor use. Our fittings are very strong and will support an axial load of up to 900 kg when tightened to a torque of 39Nm.
