A magnetic strip device attached across the end of a pick-up truck bed in order to capture loose ferrimagnetic items such as nails, screws, and the like, is herein disclosed. While primarily envisioned for use on pickup trucks, the device can also be used on vans, mini-vans, SUV's, panel trucks, trailers, and other vehicles that are used for hauling and delivering various materials. The device may be mounted to a vehicle using the magnetic attraction of the device or installed in a more permanent manner using threaded fasteners. The device will greatly reduce, if not eliminate loose metallic items from falling off the vehicle and possibly resulting in a safety hazard.
