Key clamps are the essential components for building strong, versatile, and modular tube constructions. Combined with steel tubes, they form the foundation for countless structures - from safety railings and handrails to furniture, storage racks, and industrial frameworks.
Build with key clamps and tubes
Key clamps make it easy to connect tubes without welding or special tools. Each fitting has an integrated set screw that secures the tube in place with just an Allen key. This simple system creates a strong, stable, and reusable connection that can be easily adjusted or extended.
Because of their modular design, key clamps are suitable for both professional and DIY use. They are often used to create railing systems, frames, benches, and shop fittings. The possibilities are endless.
