Preston Inception 3D 150 Seatbox After hearing what consumers wanted in terms of extras with our extremely popular Inception SL30 seatbox, we developed the Inception 3D 150. This seat box contains a 150mm base unit, which is perfect for storing larger parts such as reels. It also features a unique one-piece block that houses two deep front drawers, a deep side drawer and a shallow drawer unit. Each drawer is already provided with a division, so you can store all your small equipment in a well-organized way. As with the rest of our range of seat boxes, the Inception 3D 150 is also equipped with our unique MAG-LOK® clips, which ensure that the units are securely held together during transport, but can also be opened immediately. The footplate is now held in place by locking pins, two on each side, so that the whole can be quickly brought into position and the footplate remains perfectly in place every time.
