Alumiknox™ Truck Tool Box

The Patented Positive Closure System ("PCS")

The Positive Closure System (“PCS”) is a unique, patented mechanism for closing the lid of the Alumiknox box. Typical truck tool box closure mechanisms require force to shut the lid. Unfortunately, these designs, even under normal use, often result in bent or misaligned lids, which must be forced down on both sides to engage the latches, if not slammed to close. This malfunction occurs especially when the truck tool box is full, and tends to get worse over time.

The PCS lid closure mechanism however, uses cams which rotate 180 degrees to incrementally engage the overhead latches to pull the foam-lined lid down. This cam and latch system works without a hitch even if the lid is not all the way down in the closed position. The cams pull the lid down with increasing force, while compressing both the foam liner around the contents of the tray compartment and the bulb weather seal around the lid.

When the Alumiknox™ lid is latched down, the foam liner keeps tray contents immobile, securing a variety of objects from small hand tools to firearms to fishing rods in the 4” deep tray compartment. Prized articles can (and should) be entrusted to the foam encasement of the PCS, rather than to the jumble of chains and jacks in the single compartment of a traditional truck box or somewhere loose in the truck cab or bed. The liners are reversible, with “egg crate” and smooth surface sides, with alternative thickness sizes included to ensure a tight fit.

The PCS is operated and the lid is closed tight by simply turning either of the handles located near each end of the box. There is no need to walk around the truck to shut the other side of the lid, nor to ever have to slam it shut. The PCS is a very durable mechanism which has never needed adjustment, let alone replacement, on any of the boxes sold to West Desert’s customers, even after five years of use. However, should the need ever arise, PCS parts are easily replaced with basic hand tools.
