WCM products are made in the U S A!! A flat black Vinyl cover that goes over your battery to better show off your awesome new tray!! All of the pieces of this tray have been CNC machined out of 1/2″ and 3/8″ thick 6061 T6 aircraft quality billet aluminum, not weaker cast aluminum that others may use. The top measures 7.42 inches x 11.15 inches, you will need 1/2 inch clearance around the battery for the tray to fit. All of the mounting hardware and the hardware to bolt this box together, are included, and are stainless steel. The top and the bottom are both recessed with a deep. 200 pocket to hold the battery better, and each side has two 1/4 bolts on the top and on the bottom to make sure the battery stays were you put it. This battery box has a brushed finish. We have 4 3/8 holes on the bottom of the tray that line up to recesses in the bottom of the battery. This is very handy because if you need an abnormally long bolt to go through a frame ect. Any common hex head bolt will work with our tray. As you can see the top has a classic geometry design, and the bottom has the WCM logo of Wieland Custom Machine. PLEASE NOTE THIS TRAY ONLY FITS THE 34/78 SERIES OPTIMA BATTERY. IF YOU HAVE QUESTIONS PLEASE ASK.
