Preston Innovations Seat box. i had it for just over a year now but i just upgrade to a new Matrix Superbox.
It’s has two deep tray unit both come with pins to hold the tray in place and single tray for your winders. It also comes with a leg extended. There is a second single tray I’ll throw in for free because one of the clip has broken but you can pick them up for couple for quid and simple undo the 4 screw and screw on the new one.
The box is in good condition except on front hand screw has a crack on it but it never slipped and tight up okay. im 17 stone and he can jump on it and it doesn’t move.
its on ebay see if ya can get bargin!
