Features to know about

Full Bed Use: Roll-Up Design

With the TonnoSport you don’t have to take the cover off to carry taller or bulky gear. The soft vinyl top rolls forward toward the cab in seconds and secures with a nylon strap and super-strong buckle. When it’s rolled up, it stays tight and out of the way so you can use the entire bed. When you’re ready to close it again, it unrolls smoothly and latches automatically for a tight, clean fit.

Keeps Cargo Covered: Low-Profile Fit

The TonnoSport sits just 1/2 inch above the bed for a streamlined look that cuts wind drag and can improve gas mileage by up to 10 percent. The aerodynamic shape keeps the cover pulled tight while driving, and the low-profile design blends in with the truck’s lines so it doesn’t look bulky or out of place.

Simple Setup: Clamp-On Installation

Mounting the TonnoSport is quick thanks to six aircraft-grade aluminum clamps that attach to the side rails—no drilling or tools required. Each Tight Bite clamp locks into ridges in the rails for a solid hold. Once in place, the rustproof aluminum bows and straight rails give the cover strength and keep it looking level across the bed.

Secure Every Trip: Trigger Latch and Side Locks

When you close the cover, the trigger latch clicks into place automatically. Two slide locks along the sides add another layer of protection when paired with a locked tailgate, keeping gear secure under the UV-resistant vinyl top. The tailgate stays fully functional while the cover is down, and releasing it takes just one hand on the latch.

Always a Tight Fit: EZ-Dial Tension Control

Temperature changes can cause some covers to loosen or flap, but the EZ-Dial system makes it easy to fine-tune tension by hand. Just turn the dials at the rear corners to keep the vinyl pulled tight against the rails—no tools needed. That means the cover stays smooth, quiet, and secure through heat, cold, and rain.

by:

I like the cover. Instructions could be a bit clearer. Had to still look up a video for installation.



by:

Hard to find size, so I appreciate finding it and it being advertised appropriately. Easy enough to install and looks good. If I could change something, the side rails are mounted inside bed, would be nice if they could go on top of the side wall to not take up that space




by:

Love it - have had it for a year and its held up great. Compatible with bed rails.



by:

Awesome cover, installed easily, looks great!



by:

I had an extang cover before and liked it better. They no longer make extang



by:

For the price and install time, I really like the cover.
After installation the fit was great.
The only thing is it wasn't very clear how to install the cab weather strip but I got it.



by:

Perfect fit for Hyundai Santacruz 2025. Delivered in time



by:

The customer service at eTrailer is absolutely outstanding. They have a great process other companies should follow. I reviewed all the applicable tonneau covers and videos for my 09 Dodge 3500 4x4 LB many times before I chose the Access TonnoSport Soft, Roll-Up. It had to be compatible with complete access to a tool chest & 5th wheel. Once I received the item, the directions described the pieces in "Access's" technical terms. Some pics were dark contrasted, hard to figure out, drawings would have helped. I made slight adjustments according to the troubleshooting page. Overall, pleased with product & the outcome.



by:

Excellent product instructions could be little better but after some reasoning was able to figure it out.



by:

Overall it has been a great product. I do wish that it wasn't so baggy. But, I understand that the material it is made from tends to do that depending on temperature.



by:

The install was easy,I installed it by myself. I have taken it through 15 car washes, it has been through 3 rain storms and has not let any water into the bed. If purchasing again I would get the same exact one as i love the extreme low profile.



by:

Good value. After one year in the hot Georgia sun, an especially cold winter, and lots of recent rain; the cover continues to hold up well and looks as good as the day I installed it. The installation was fairly easy, but the instructions could use improvement. However, with a little patience the result is nearly a custom fit. I have no negative comments regarding the quality and effectiveness of the product. Easy to use and keeps cargo dry even in the hardest of rainfall.



by:

The Access TonnoSport Soft Roll-Up Tonneau Cover arrived in great shape. I had no trouble installing it on my Maverick. It looks great and works great. Very happy with my purchase.



by:

Looks fantastic on my 2016 Nissan Titan XD I love the low profile
Install was less than 15 mins following the included instructions.
Works well with the Utili-track installed in my bed.
Highly recommend.



by:

While initially when I got this cover, I thought it was good quality. After using it for about 10 months, I see that is not true. The adhesive on the back of the Velcro that holds the cover down is not sticking anymore. So the cover is not staying closed. I called support about this and they did send me out new Velcro strips. While I started installing the new strips, I notice the cover maturely has been rubbing against the metal bars that gives the cover its tautness. So they will rub through the cover material probably right when the warranty expires. I really wish I got all my $ back and would buy a better quality cover.



by:

Well made topper, instructions could use some work! A video would be nice! All in all a decent cover



by:

It fits and looks great. Shipping was extremely fast!! I didn't give it a five star rating because the cover mounting instructions were very difficult to follow and not specific to my compact pickup truck.



by:

The cover fits perfect on my 2024 Silverado. It was pretty easy to install with help from a installation video. I took my time and it took about an hour to install. I needed this type of cover so I could install my ladder racks.



by:

Excellent cover I love it! Engineering figured out an excellent solution to a tough situation with the Santa Cruz’s truck body constraints and it works as good as it gets. No drilling! Only 4 stars because I did have to debur a number of aluminum extrusion parts. But don’t get me wrong, This cover is exactly what I needed. Good job to the engineers who designed it. Note: I used a set of thick washers (1/8”) to shim up the rails slightly higher than flush of the bed rails so the tail gate could close.



by:

When installing the rails they would not sit square after tightening the clamps. The bed I have on my Santa Cruz has a plastic liner. Not sure if that was the problem. My son-in-law put two washers behind each clamp in order to square up the rail. That seemed to work. After the headache of trying to figure out how to correct the problem our solution worked. The cover itself looks great on the truck.



by:

These covers are the best. Getting this one for my 3rd new truck in 14 years. The last one is still in great shape and handled a 40" snow load in 2021. That cover was 5 years old at the time.



by:

Product is great the directions not so great. After the bulkhead rail and side rails are put in tonneau cover should be rolled from the back to the front so you know exactly where everything's going.



by:

Great cover for a fair price. Easy installation and a sleek, seamless look. This cover is far superior to the one this truck had for its first 25 years.
