Doughty 3 Position Tank Trap - Highly Versatile Lighting Truss Base Plate

Award-winning Boom Base
The 3 position Doughty Tank Trap was awarded the ABTT Engineering Product of the Year Award in 2017. Its great flexibility allows you to build the rigging everywhere, even near an obstruction, making this boom base favourable in the industry since the launch. 

To Support 3 Poles for Suspending Lanterns
It is a multipurpose floor plate to suit and secure a 48mm diameter barrel, pole or truss vertically. Up to three barrels can be installed onto one boom base via the detachable receivers in the centre, at the edge or in the corner of the plate. The barrel(s) can then be used to suspend loads. These loads can be, but not limited to, lighting fixtures, video projectors, sound systems, and set pieces. This tank trap can be used as a standalone system or as a part of a larger installation.
