"Manufactured from highly resilient, black powder-finished aluminum panels, the Pace Edwards Switchblade Metal Retractable Tonneau Cover is ideal for those who often find themselves requiring at-a-moment’s-notice payload access. As sharp-looking as the illegal blade for which it was named, this top-of-the-line tonneau allows full rear visibility and installs in no time at all. Equipped with innovative Continuous Tension Spring technology, this cover requires only that you activate the pinch grips underneath and the cover retracts with butter-smooth efficiency. To close, just tug on the convenient pull-strap. Meant for crew-cab, extra-short-bed trucks, it also comes with a removable canister and rails for total, tail-to-cab access.
