Features to know about

Secure Every Load: 1" Thick Aluminum Construction

When you’re carrying tools, camping gear, or anything that matters, protection from weather and theft is key. The RetraxPRO MX uses impact-resistant 1" thick aluminum slats that can handle up to 500 lbs of evenly distributed weight. The solid build resists dents, prying, and harsh conditions so your cargo stays safe under a cover that’s built to last.

Quick Access Without Compromise: Retractable Manual Operation

Getting into your truck bed shouldn’t mean removing the cover. The RetraxPRO MX opens and closes smoothly with a pop-up locking handle and sealed ball-bearing rollers that never need lubrication. The cover glides along the rails so you can reach your cargo in seconds, or lock it at any point to secure part of the bed while leaving room for longer items.

All-Weather Confidence: Sealed Protection and Drainage System

Rain, snow, and dust stay out thanks to weather stripping and foam seals on all sides. The cover overlaps the top of the tailgate for a tight fit, while two drain tubes route water out of the canister to keep it dry inside. Even in heavy weather, your gear stays clean and protected.

Sleek Look That Works Hard: Low-Profile Matte Finish

This cover sits just 1" above the bed rails for a flush, streamlined appearance. The matte black finish is scratch-resistant and won’t fade in the sun, keeping the truck looking sharp. The compact, angled canister at the front of the bed gives you more room for cargo and stays out of the way.

Simple Setup: No-Drill Installation

Mounting the RetraxPRO MX doesn’t require drilling. The rails clamp easily to the bed rails, and the pre-assembled canister drops right into place. Once installed, you’ve got a dependable cover that locks solidly, retracts smoothly, and looks like it belongs there.

I have owned this roll top truck bed cover for a year now and still absolutely love it. I've owned other similar ones over the past twenty five years and this one is and has been the best. Sturdy, solid and so far, maintenance free. It certainly more weather (water) resistant as well. It definitely was more expensive than the other covers I've purchased in the past but the bitterness of poor quality remain forever and the higher cost of something well made are soon forgotten as you use the product everyday. Highly recommend.



by:

My third Retrax. The fit and finish is on point. Nice job... Again!



by:

Easy installation. No problems after a year on my truck. Very satisfied with the purchase.



by:

Only had this cover for a few weeks but it so far.



by:

On my previous truck, we had installed a soft snap-on tonneau cover. While it looked great, its performance over time decreased significantly, particularly in cold weather! So this time around, I decided to splurge and purchase a high-quality roll-top hard cover. I am SO HAPPY that I did! As importantly as its ease of installation and use, it is lockable so I will no longer have sleepless nights while traveling, worrying about the items in the truck bed. eTrailer was a great help in expediting the delivery of this item, as my HOA requires pickup trucks to have their beds covered... Thank You!



by:

The RetraxPRO MX Hard Tonneau Cover was very easy to assemble and install. Item was packaged very well for shipping. I would recommend this tonneau cover.



by:

I had some damage. It was a dent in the main box. I went ahead and used it anyway. I didn’t call or ask for return because I needed the cover right away and I messed the box up which would make the return hard to do. This was not etrailers fault. It was a packing issue from Retrax.



by:

Very well built and easy to use, great product.



by:

Vert good quality. No failures despite repeated use.



by:

This cover looks amazing and rolls so smooth. No heavy trifold flipping. I have the 8’ bed and it works great.



by:

Nice product. More difficult to get the rails attached than it should have been. Very glad I had 2 strong guys helping me.

Love the results.



by:

I like the old latch system better.
The
wire loom for drains is not going to last long.



by:

Great quality very happy with this. Would recommend to anyone looking for a nice retractable cover.



by:

Item came on time and was very easy to install, but you need somebody to help you lift and put in the back of the truck as instructed. Its not that heavy, but just too awkward for one person to lift and place.



by:

Easy enough to install and looks good. Works as I’d hoped and just need to see how it holds up in the Midwest winters ??



by:

It’s seems high quality but this review is too soon to tell . I would rather give reviews after a few years of use but for now the product seem exceptional. It was just I stalled today.



by:

The tonneau works well. I wanted something that would be pretty secure (aluminum and locking) and easy to open/close. It is all those things! One handed open/close. Few pieces that are below the cover level so it doesn't interfere too much with what you have in the bed. Install was ok - definitely two people are easier than one.
Two downsides. The roll up area does take bed space - more than I'd like. Also, it is not watertight. Not terrible in the rain, but a good downpour or car wash gets water in the bed.



by:

Quality product. Bought to protect and hide fifth wheel hitch. Does a great job!



by:

This was a really easy installation. 2026 GMC 3500 DRW. I did it the install myself pretty quickly (except for lifting the combined rail/cover into the truck). One person on each side to guide and lift while my daughter lifted the weight in the middle of the bed worked well. The few connection screws required fit easily. Seals at the front of the truck and on the tailgate are smooth and complete. I didn't make both sides parallel when first installed. I loosened the middle and tailgate ends of the rails, adjusted the spacing distances, and it's perfectly in align now. One person can very easily expand and contract the top. The two drain hoses won't fit the holes in the truck bed. I'll pickup something from Home Depot or Lowes to append a reducing method. I really like this bed cover!



by:

Should put actual installation instructions with the product inadition with the on line.Something was catching when attempting to operate. Semes to work ok after it broke free.



by:

The shipment was supposed to be delivered yesterday, so I stayed home from work to receive it. I live on a busy street in St. Louis city, or a corner lot. The instructions were to deliver it around back to the garage door. It finally arrived after 9pm on the front steps, which are within 8 feet of the sidewalk. Good thing it's so heavy and it didn't "walk off".



by:

This is a very sturdy tonneau cover and looks great on our 2026 Ford F-450. The materials and build quality are top-notch. The installation is straightforward, and I recommend you watch the video(s) prior to performing the installation. The unit is heavy, and you will need a strong helper. This is our first hard tonneau cover, and we are very pleased with our purchase.



by:

Received my order in a timely manner. It was an easy install. I’m 65 years old and was able to install by myself.



by:

The instructions were definitely lacking—ended up finding a decent YouTube video. The box itself wouldn’t fit between the rails on the inner sides of the bed (see pics), so I had to use prybars to seat it past the rails.

Functionality: seems very solid once installed and rollers help it slide easily either direction. I’m not convinced it’ll hold much water out, but that’s partly due to the ram box hinges next to the tonneau rails, then not a lot of pressure between the tonneau and the top edge of the tailgate. I also had a $500 tonneau in the past with weather stripping along the front box to scrape debris from the top side of the tonneau as it retracts into the box at the front of the bed. This doesn’t have that, so it seems debris will accumulate inside the box and I’m not sure how easily it will be to clean inside the box.

Time will tell if this is worth the price tag, but it does feel very sturdy once installed.



by:

I was hesitant to try a canister type roll up bed cover after only having hard covers or a soft roll up above bed cover before. I'm glad I did...

It still gets 5 stars because even though the box for the rails was damaged, no parts were missing and there were no dents or scratches on any of the pieces.

The install was easy, did it by myself in a couple of hours not rushing to get it done but working at a leisurely pace. The only time I needed help was to position it in place after the side rails were attached. The part that took the longest was measuring and adjusting the width between rails from the front to the back to get them within spec so the cover moves smoothly and easily with no binding. The instructions were easy to follow and it is simple to put together and install. Just take your time measuring between the rails and it will glide effortlessly.

I like the size of the canister, it doesn't take up much space at the front of the bed, even though it has 8ft to roll up. It seems as if it will be pretty water repellent with the rubber seals and gaskets. It rolls up easily and doesn't retract fast and slam into the canister. It also rolls out easily all the way to the tailgate. Unlike previous covers I have had, this one doesn't require the tailgate to be closed to work properly. The cover can be extended all the way to the tailgate and you can open and close the cover or tailgate independently of one another. I also chose this particular cover because it had the anywhere lock feature rather than only a few set locking points. The matte aluminum is a nice clean look, and it seems like it will be less prone to sagging in the middle as time goes by. This particular model sits just a little above the bed (the bed cover rails sit on top of the truck bed) but the canister isn't any higher than the rails or the cover itself when its open or closed. It looks seamless and clean.

It's only been a few days since install but as of now, I couldn't be happier having chosen this bed cover. And as always, etrailer makes the ordering process easy and worry free with their vehicle specific fit, fast shipping and fair prices.
