Features to know about

Secure Everyday Hauling: Hard Roll-Up Hybrid Design

Many covers make you choose between a soft roll-up that’s easy to use and a hard cover that’s more secure. The TruXedo Sentry CT combines both. It uses 3/4" thick aluminum slats under a premium 5-layer woven polyester and vinyl fabric to deliver hard-cover strength with soft-cover convenience. You can roll it up in seconds using the release cables at the tailgate, then lock it down with slam latches for solid protection. With a 400-lb evenly distributed weight capacity, it can handle tools, gear, or luggage without flexing.

Streamlined Look and Better Efficiency: Ultra-Low-Profile Rails

Bulky covers can stand out or create drag, but the Sentry CT keeps things clean. The side rails sit at a 15-degree angle so the cover rides just 1/2" above the bed. That low stance blends with the truck’s lines while cutting down wind noise and drag. The all-black aluminum slats and matte finish fabric create a uniform, “blacked-out” look that stays sleek whether rolled up or closed.

Quick Access When You Need Full Bed Space: Roll-Up Function

Some hard covers have to be removed completely to haul tall or oversized cargo. With the Sentry CT, you just roll it up. The cover secures neatly at the cab with built-in safety straps, staying low enough not to block the rear window or third brake light. If you want to take it off entirely, the quick-release guides let you remove it in seconds without tools.

All-Weather Durability: Five-Layer Fabric Over Aluminum

Weather can ruin a soft cover fast, but the Sentry CT’s fabric is built to handle it all. The 5-layer polyester and vinyl top shields against UV rays, rain, snow, and dust while staying flexible in extreme temperatures from -40°F to 120°F. The heavy-duty construction keeps the slats aligned for smooth rolling and resists fading or sagging over time. Rubber seals along the edges keep water and debris out so your gear stays clean and dry.

Simple Setup That Stays Square: Self-Leveling Clamp-On Rails

Installing a tonneau can be a hassle if the rails don’t line up right. The Sentry CT’s clamp-on side rails make setup easy with no drilling required. Built-in lips keep the rails square as you tighten the clamps, so the cover rolls evenly every time. The in-bed mount leaves stake pockets free for tie-downs and racks, and the rails only protrude 3" into the bed from each side, keeping space for your cargo.

The Sentry and Sentry CT by TruXedo are hard roll up style truck bed covers that feature an extra low profile.The Sentry comes with a leather grain vinyl fabric and the Sentry CT comes with woven matte black fabric. Both feature fabric that is pressure bonded to heavy duty aluminum slats, making Sentry the ultimate in durability and security.Each cover ships with a cover assembly, driver and passenger side rails, and all the hardware necessary to install it on your truck. The only tools necessary are a half inch wrench and scissors.Clean the bulkhead area with alcohol. Adhere the rubber seal to the bulk head, making sure to align the seal with the inside edge of the bulkhead. Trim the seal to sit flush with the bed caps.Position one side rail on the truck bed. Make sure the rail sits level on top of the truck bed.

Slide the rail towards the bulkhead so that the foam seal is compressed about half way. Install a clamp in the center of the rail, using a half inch wrench to tighten.Install the real clamp about 12 inches from the tailgate. To ensure a proper seal, put pressure on top of the rail when tightening. Install the front clamp about 12 inches from the bulkhead. Repeat on the opposite side.Place the cover assembly on the rails at the bulkhead.

Line the screw head on the underside of the cover assembly with the slot in the rail on each side.Slide the header guides towards the rail to secure the rolled cover to the rails. The header guide will click when it is securely fastened.Unroll the cover to the tailgate. Close the tailgate. Then push down on the end of the cover to latch both sides. Secure the hook and loop on both side rails before driving.To open the cover, drop the tailgate and pull down on a release cable.

Lift and roll rear header.To drive with the cover in the open position, both straps must be secured to the restraining straps. To releasee the strap, push the tab up.The installation is now complete.

After reading the instructions a few times it went together easily and fits like a glove. Very happy.
by:
The only minor annoyance is that you have to open the cover a few inches every time you close the tailgate or it pinches the rubber gasket and puts undue pressure on the cover.
by:
Crappy directions. You need better cross section n to show how rail goes on truck . I spent hours trying too figure it out. My cover was damaged in shipment - scratches on black paint - could you send touch up black spray can?

Sorry to hear all that, Garvin. We don't have matte black paint that we can ship out to you, but we can credit you $15 to purchase some locally if that would work. Just let me know if you want to proceed in this way.

The quality of the cover overall is quite high and has potential when fitting correctly. The problem is the fit on the RamBox trucks. I had to heavily modify the rails to get them to fit properly. I was told to return I would incur a 15% restocking fee and get no credit if it was not able to be put back on the shelf. So I was tasked with finding a solution on my own (tech support was no help). I ripped 1/4" off the aluminum rails using a table saw and notched around the bolt holes. After this modification it fits well.
by:
If it was practical to return it, I probably would. I am a farmer and a mechanic, so I can live with it, but not very good. Install was complex and baffling as I have a Ridgeline which is not standard. The worst feature is the back latch or uses a cable pull and two sliding latches which are just trash. Poor design, bad functionality and breaks easily. Mine jammed up and would not unlock, and ended up breaking the cheap plastic lock assembly to get in, result of poor design. Still jams and easier to just leave it unlatched and unlocked. Small rubber seal at endgate fell off and lost. Looks good, secure when it works. Expected more.

There is a lot going on with the cover. Would you be able to send a picture of the cover and the serial number from it.

@JennyN Thank you for sending the pictures. I reached out to manufacturer and they are sending out a new latch system for you.

This is a well made bed cover. Easy to use, solid and secure, but not in the way when open. I love that it does not block my back window when driving with it open. The fabric on top of the aluminum is high quality and looks good. Highly recommend, I'm actually happy there was not a back flip for my truck, as I wanted to ordered one, but this is a better solution.

After a year the cover is still looking great and working great. I wish I had purchased one of these when I purchased my truck, as it is nice to be able to securely store stuff in the bed of my truck.

by:
Overall this has been a great hard tonneau cover. Installation wasn't too difficult, it's not 100% water/dust proof, but I don't think any tonneau cover ever is. It stood up to several heavy snowfalls over the winter without any issues and it still looks good with no noticeable fading of the vinyl covering. The roll-up convenience is great when you need the whole bed compared to a fold-up tonneau that can block the rear window when folded all the way up. The only issue I have run into is occasionally the rear most clips that lock the tonneau down can slide out slightly from their fully seated position and it can make it difficult to close. It's easy to push the clip back into place, but the first time it happened it was a little frustrating.
by:
After one year, still solid and working perfectly. Keeping secure and dry.
by:
I love my truck bed cover! I was a little hesitant to buy something online but the reviews were good and the description was exactly what I wanted so I took the chance. Everything went well. The directions for installation were explicit and easy to follow. Everything lined up perfectly and operated as expected, especially the waterproof part as only a few drops of water have ever made it inside the bed and only in extreme downpours with excessive wind. It has been a year and the only thing I wish I had done differently was get it earlier! I bought it before a trip and ended up installing it in freezing temperatures . . .
by:
Easy installation and easy to use. Cover looks good on my truck and appears to be very strong
by:
It does a great job at what I wanted. Lockable, a rollup that impedes full bed loading less than most, does not block vision from back windshield. It is sturdy reinforced so doesn't sag or or make wind noise. Nothing is break in proof but you have to be pretty determined to get in this. Nothing is rainproof but the limited amount is very acceptable to me. The top still looks good after a year of snow and sun. The installation was a little fussy and you do have to have your rails diagonally squared! 3 hours for me, but I could do it in half the time now with lessons learned. I thought it was pricey but I'm happy with it and would buy it again.
by:
The cover is great and looks good too. It’s very easy to install and hit low to the bed rails of the truck. The interlocking aluminum strips make the cover heavier. But the fact that the lock together and the is locking mechanism in a couple places along the rail add to the security of the cover. There are two quick releases at the end by the cab allowing me the ability to remove and install the cover quickly. Clicking the rear end in place is quick and easy.
by:
Fits good easy to install with my sports bar

Truxedo and E-trailer got my tonneau cover out and delivered in 7 days. I installed the cover as soon as I received it. Installation was very easy with pretty clear instructions. Just looking at the cover it seems to be of good quality. I have yet to drive my truck so I can't say how it actually preforms in different weather conditions. From what I see I doubt it is totally water proof. I can see a couple of small area where water will leak in. But we will see. The only complaint I have so far is the seal tape they supply for the front of the bed to be used if your truck bed has bed caps. Rams do. This seal tape is meant to fill the gap at the front. The tape should be better quality. It did not want to stick to the bed. I did follow cleaning procedure before I applied it. This is the only reason I did not give it 5 stars. These hard roll up covers are pricy so I hope it is a quality product. As far as E-trailer and their sales/service they are the best.

Thanks for sharing your honest feedback about the cover, Brian. Let us know how it holds up to the rain and the elements when you get to test it out.

by:
This tonneau cover was easy to install and is plenty rugged to hold up to a 24" wet snow load. It rolls up easily. I was hoping it would improve my fuel economy, and I suppose it has about 1/2 to 1 mile/gallon when I go on long trips at highway speeds. About the only complaint I have is that it is not fully waterproof and small amounts of wat water leakes in along the bed rails. Nothing major though.
by:
Great product,

Been a year since I installed this cover on my ‘22 Ram 2500, it has been great! No issues whatsoever so ever, very happy with my purchase still!
by:

The product arrived in a damaged box and had damaged rails. I reached out right when I opened the box, spoke to a rep and submitted pictures., I received no confirmation that the pictures were received, or that replacement parts are processing and, on the way, this is still an open issue.

That's not good Edward! I'll get that taken care of for you.

by:
This is the PERFECT cover!
by:
I really like the design of this tonneau cover. The roll-up design allows me to see out my back window when hauling items higher than the truck bed. Also, it was able to keep my truck bed dry during a significant rainstorm. I would suggest holding the tonneau by the fabric on the sides when rolling closed opposed to placing your hand on the ribbing to reduce the chances of pinching your fingers.

I have been on a couple of trips where I've needed to open and close the cover repeatedly. It seems to be quite durable and the locking mechanisms work as designed.

Installation was a little more difficult than anticipated since my drop-in bedliner reduced the width of the truck bed between the side-rails at the front of the truck bed where the tonneau attaches. After finding a wider area between the bed-rails, I was able to wedge the the top of the tonneau into the side-rails and push the tonneau through the side-rail track towards the front of the truck bed. It allowed we to wedge the bedliner wider increasing the width between the side rails. I was able to install this by myself in about 90 minutes even with the complications.
by:
shipping was very fast as ususal, it arrived and the box had damage but a close inspection verified no issues with product. installed by myself a little akward but do-able after reading the instructions and watching the install video it took about 45 minutes to install. There were some fitment issues as the tonneau cover would not stay closed and the tailgate was very hard to open so I shimmed the back corners of the rails with large washers just inside by the tailgate 2 on the right side 1 on the left, I also had to move the rails back about 1/4 inch to ease the opening of the tailgate. So all installation issues are resolved but only 4 stars because the locking mechanism is less than robust. I got the material finish instead of the vinyl it looks very nice. It has rained several time since installed and it keeps most of the water out, what water there was came in by the tailgate I installed this on a 2015 F350 with 8 foot box, it is much easier to open and close than a bak hard folding top.
by:
Installation was pretty straight forward, around 30-45 minutes total. Once installed, the look of the cover is fantastic. Very low profile and the matte black finish on the cover material looks great.

There was a factory quality defect with the installation of the side latches that run up both sides of the cover. Each latch has a cable that connects from the cover to the side latch. As the cover is rolled up, tension gets applied to that cable and it releases the latch allowing you to seamlessly roll-up the cover. On my cover, two of the cables were too loose and would never get enough tension to release the side latches. I could only roll-up the cover about two feet before it would stick. The cables are not adjustable so you cannot fix this issue without new parts.

I contacted Truxedo and they sent out a repair kit for the side latches. I was able to install the new cables and the cover functioned as it should. It was a total of 24 days from the time of ordering my cover until it was fully functional.
I am happy with the look of the cover. I have not had a chance to see how weather tight it is. Hopefully the issue with the side latches is a one-off defect and not representative of the overall quality of this product. I have made several purchases from etrailer and this is the only hiccup I have ever had.
by:
Loving this cover. It's super-simple to use - just roll it closed and run your hand down the sides to press the hook & loop fasteners down. I wanted a retractable cover, but didn't want the big box taking up space in the bed of my truck. This cover is easily-removed so I have the full bed available for use. The only downside I've found is that it can't be left in any partially-open positions (like my old retractable could).
