Doughty Mammoth Swivel Coupler

The Doughty Mammoth Swivel Coupler is constructed from high tensile Aluminum Extrusion. It provides a firm and quick fixing between adjacent bars at any angles whilst allowing 360 degrees of movement. A great example of how to use this coupler is bracing a truss with another tube. 

While a regular coupler can fit 2'' diameter tubes only, this large swivel coupler can fit wider tubes of 2.5'' diameter. Broadly used in the theatre, film, TV and photographic industries.

Parallel and 90-Degree Coupler versions are also available.
