Solid clamps – the original aluminium tube connectors
Tube connectors are flexible, quick and easy to use
RK tube connector – unbeatable variety
Thanks to their simple clamping principle, the aluminium tube connectors enable the fast assembly of both round and square precision tubes. The huge diversity of this system is what makes it an attractive and cost-effective alternative to conventional welded connections. Our application expertise and the experience we have gained over several decades as a manufacturer of clamp connectors give you security for individual handling of RK tube connection systems.
Connecting tubes with different diameters and cross sections to one another
The cast aluminium or extruded aluminium tube connectors impress with good mechanical properties, a wide range of variants and optimum value for money. The Solid Clamps product range currently comprises clamp connectors with a diameter of 8-80 mm for round tubes and of 20-80 mm for square tubes. More than 170 basic types in over 400 different variations are available. The selection of variants, clamp diameters and range of combinations is unmatched.
They are available in three clamp connector designs: in the multi-variant single-piece industrial design, in a multi-piece block with straight external contours or in the form of the elegant quad® tube connector.

| The complete tube connection system. The huge range of models, clamp diameters and possible combinations is unique on the market. | The straight external contours distinguish the block form range from the industrial design range in terms of appearance. The multi-piece versions enable the clamp connectors to be integrated into existing constructions retrospectively. | Made from extruded aluminium profiles, the cuboidal, anodised connecting elements have a timeless appearance and can withstand exceptionally high loads. |
