This is a Jeg’s Aluminum Battery Relocation Box. It’s a flat pack kit that bolts together. Comes with all the hardware you need to bolt it together, and hold it in the car. The box outside dimensions are 13 7/8″ Long x 10 1/4″ Wide x 10 Tall. Not entirely sure what size battery this will fit. I listed this as new because I never actually installed it. Only thing I did was bolt it together when it showed up, and tried to slide it in my 3rd Gen Camaro’s trunk well, and realized it won’t fit. So it kinda kicked around the garage for a bit. All the hardware that came with it is there, the bag with the cables was opened to remove the hardware to bolt it together. Parts in this kit. 3ft long Negative Battery Cable (3/8 Ring Terminal to Battery post). 16ft Cut-to-Fit Positive Battery Cable (1/2 Ring Terminal to Bolt on Battery Post). Vent Tube w/ plastic elbow. (2) Threaded Rods. (1) Battery Hold Down Bar. (2) Flat Side Panels. (2) End Panels. (2) Top/Bottoms (one of these has the dent from the picture). Box and Rod Hardware.
