Martin Low Profile VDO Sceptron/Fatron Half Coupler

The usual way of hanging a VDO Sceptron or VDO Fatron is a sliding bracket plus a standard clamp, which works but stands the fixture off the bar. This coupler replaces both: it carries an M6 bolt and nut that slide straight into the back profile of the batten at any point along its length, so the clamp body sits directly against the extrusion.

The result is a noticeably shorter distance between fixture and truss, which matters when battens are being hidden behind a header, run tight to a ceiling or packed into a tight trim. Position is free anywhere along the channel, so spacing follows the design rather than fixed hole centres. Sold per piece, P/N 91611790, and it fits both the VDO Sceptron and the VDO Fatron.
