Doughty Tank Traps - 3 Position Boom Base

The 3-Position Doughty Tank Trap / Boom Base was awarded the ABTT Engineering Product of the Year Award in 2017. With great anticipation, we now bring it to market in the Americas and look forward to the customer response following the success the product has seen in Europe. 

It is a multipurpose floor plate used to secure 2'' diameter barrels, poles or trusses upright. One boom base can support up to 3 poles on the positions indicated in the diagram. The barrel/s can then be used to suspend loads such as lighting fixtures, video projectors, sound systems, set pieces etc. This tank trap can be used as a standalone system or as a part of a larger installation.

This tank trap is fitted with a detachable receiver which may be screwed in the center, at the edge, or in the corner of the plate. With the receiver removed, the plate may be inverted and used as a base plate to suit various sizes of the truss. It does not include truss connectors or fixings to mount the truss to the plate.

Broadly used in the entertainment industry in places such as theatres, event venues, museums etc. The tank trap can be easily transported and stored by a Tank Trap Dolly
