This is a 3mm steel powder coated bracket that allows the user to remotely mount the Tank series winch control box using a single mounting point to the fixture. The adjustable mounting slot allows for adjustment of the position of the control box bracket, It is also long enough to accept more than one mounting bolt should you wish. We would recommend an 8-10mm mounting bolt. The dimensions are 150 x 100 x 15mm We would recommend using through bolts with washer and nyloc nut for the mounting of the control box to this plate. Cap head bolt of four quantity of 5mm x 30mm total or 25mm thread length is the required minimum length for control box mounting.
