Product Description

Kee Klamp C50-66 – Single Swivel Socket

The Kee Klamp C50-66 Single Swivel Socket is an articulated fitting designed for use with 33.7mm outside diameter tube. Providing up to 170° of movement, this swivel component offers the flexibility needed when working with non-standard angles or irregular surfaces—ideal for creative or complex builds.

Engineered from galvanised cast iron, this fitting offers outstanding corrosion resistance, making it a reliable choice for both indoor and outdoor structures. As part of the Kee Klamp handrail system, it integrates with a wide range of compatible Kee Klamp fittings, allowing you to construct safe, modular, and highly adaptable railing or support systems.

Often used in conjunction with straight and fixed-angle fittings, the C50-66 plays a valuable role in projects where angled connections are essential—such as sloped ramps, staircases, or uneven terrains.

Please note: Swivel fittings like the C50-66 are not intended to carry significant bending loads. To ensure the integrity of your structure, use this fitting alongside rigid galvanised handrail fittings and avoid designing entire frameworks using only swivel joints.

  • Designed for 33.7mm O/D tube

  • Manufactured from durable, galvanised cast iron
  • A key component in the Kee Klamp pipe fittings range
