A Kit Box includes all parts needed to install a Dynamic Trim Control System with one pair of fast-acting straight interceptors (2x interceptors with 3m cable and cable covers, 1 distribution unit with 4m power cable and 1 control panel with 7m standard cable). Any base installation can be expanded with up to two extra pairs of Series S interceptors, thus allowing a total of six interceptors without any need for additional connectors or power supply.
