Designed for the large scale pole mounted installations that standard Ø50mm poles cannot hold, the BT7853 is a heavy duty alternative made from 3.2mm thick steel capable of supporting these heavier loads. The poles are available as standard in 2m or 3m lengths which can be cut to an exact length if required, and feature safety bolt holes top and bottom for a secure installation. The BT7563 is internally unobstructed for cables to pass through easily and poles can also be linked together to create even larger installs, using BT7824 external pole joiners.
