Features to know about

Locked Storage That Still Moves with Your Load


Latch Retrax cover anywhere on rails

Leaving gear in your truck bed usually means choosing between access and security. This cover uses a pop-up locking handle that latches at any point along the rails, letting you keep cargo near the cab covered while oversized loads extend out the rear of the bed. Hard aluminum construction creates a rigid barrier that can't be sliced open like a soft cover. The low-profile lock stays hidden beneath a weather-protected lid to shield the key cylinder from dirt and moisture. Close the cover with your locked tailgate and the bed stays secured, while the independent tailgate operation lets you open or close either one without disturbing the other.

Rack Space Without Sacrificing Bed Access


Retrax Trax Rail System

Truck beds fill up fast once bikes, ladders, recovery gear, or kayaks come along for the trip. Integrated T-slots built into the side rails let you mount compatible ladder racks or roof rack crossbars (sold separately) from brands like Thule, Yakima, and Rhino Rack directly above the cover. Because the rack system mounts into the rails instead of the tonneau itself, the retractable cover still slides normally underneath. The 1" thick aluminum construction also supports up to 500 lbs evenly distributed while the cover is closed, giving you additional load support for snow, gear, or rack-mounted cargo.

Smooth Retraction Without Hinges or Snaps


Retrax sealed ball-bearing rollers

Folding covers and soft roll-ups can become frustrating once dirt builds up in hinges, snaps loosen, or straps start flapping around your bed. This retractable design rides on sealed ball-bearing rollers that keep the cover moving smoothly along the rails without lubrication. There are no exposed hinges, hook-and-loop fasteners, pull straps, or springs to manage during daily use. Pop up the handle and slide the cover from either side of your truck for fast bed access without removing panels or folding sections out of the way.

Spiral Track Canister Reduces Wear During Retraction


Retrax spiral track system

Retractable covers see constant movement every time the slats roll into storage. Inside the canister, a spiral track system keeps the aluminum cover from rubbing against itself while retracting, which cuts down on wear as the cover cycles open and closed. The canister also uses an angled bottom that leaves extra clearance underneath for long cargo or smaller gear near the cab. Integrated water management channels runoff into the canister drains, and the included drain tubes route water through the factory bed holes to help keep the stored cover dry.

Hard Aluminum Coverage Against Weather and Impact


Retrax weather strip

Rain, road spray, snow, and airborne dust can work their way into exposed truck beds during long drives or overnight parking. This cover uses weather stripping at the bulkhead, foam seals along the rails, and a tailgate overlap to reduce water and debris intrusion across the bed opening. The 1" thick aluminum slats resist dents and impacts from shifting cargo or falling debris, while the matte black finish resists scratches and sun fading. Low-profile side rails sit just 1" above your truck bed for a streamlined appearance that still leaves clearance for most 5th-wheel hitches beneath the cover.

No-Drill Installation on Your Bed Rails


Retrax installation parts

Drilling into painted bed rails can permanently change your truck and add extra installation time before the cover ever goes on. This system clamps directly onto your bed rails using bolt-on clamps instead of requiring drilled mounting holes. Because the retractable cover comes preinstalled inside the canister, most of the assembly is already handled before the unit is lifted into place. After positioning the rails square on the bed and tightening the clamps, route the included drain tubes through the factory bed holes and the cover is ready for daily use.

  • Can Yakima OverHaul HD and Hard Tonneau Cover Be Installed On 2026 Honda Ridgeline
    Hey Tony! Until recently, there was no way to install the Yakima OverHaul HD on the Ridgeline without drilling to add Yakima HD tracks onto the bed rails. This is no longer required since Retrax came out with the RetraxPRO XR Hard Tonneau Cover # RTX78TR. This tonneau cover has T-slot rails which will allow you to install the OverHaul # Y01151-5755 (60" crossbars) or # Y01151-5855 (68" crossbars). Yakima doesn't list a fit for the Ridgeline so you will need to measure and see which crossbar...
