The Retrax IX is a flush-mounted retractable tonneau cover constructed of durable aluminum slats linked by a strong elastomer hinge, helping to eliminate the opportunity for water and debris to enter your truck bed. When combined with the UV-resistant matte finish powder coat, the cover helps keep your truck bed and cargo protected and secure in the roughest of conditions. The Retrax IX's convenient release handle allows the cover to roll into a custom spiral canister at the front of the bed, protecting the cover and reducing wear and tear. Sealed roller bearings inside the aluminum rails deliver smooth, frictionless operation with no binding and virtually eliminate springs and failure-prone moving parts. Retrax IX's unique, adjustable latch stops allow you to secure your cover in any three positions of your choice for the ultimate in hauling capacity and flexibility, letting you use your truck how you need to. This cover, manufactured in the U.S.A. with global materials, installs easily in just 30 minutes, and the "No-Profile" appearance is sure to keep your truck looking good and cargo secure for years to come.
