Release both locks simultaneously by pulling the cord from either side. Heavy duty nylon latches provide 1/2 in. surface for solid positive engagement.

AUTOMATIC TEN POINT LOCKING

" Fits well, easy to install "
By John W. - WI
" Really nice cover, super easy to install. Customer service was great....the only 2 complaints I have is #1. let customers know your company has to build these before shipping #2. invent a way to drive around with cover in open position, similar to BAK -FLIP Co. system. Otherwise , the top is great !! I also ordered the Adarack Pro Sys. Thanks to your instructions was easy to install. Note: I purchased a special router bit to auger out stake pockets. This bit made it super fast to install. You may want to consider carrying this bit yourselves. I ordered mine through BullRing in California. $10 bucks !!! Thanks Guys, love the set-up "

" Purchased tri-fold with aluminum diamond plate finish. Much preferred to all the black versions out there. Well made and relatively easy to install. "

" Received the LOMAX Professional Series cover for my F250 in record time. Installation took a little bit, as I have a drop in bedliner which needed to be trimmed a bit to allow for proper fit of the cover. So far, it has been through the carwash a couple of times and other than a drop or two of water, has been watertight. The silver metal is keeping the bed cool in direct sunlight, while the black bedrail cover right next to it gets hot, so this should be great for carrying camper supplies and not having them roast in the summer. I have a bit of concern on the long term strength of the plastic hardware under the cover, but that is only a feeling. One good thing is that ACI at least provides access to spare parts, which is something you never see, so I am willing to see how it does over the next few years. Looks great, and the wife loves it as well. "

" Easy to install. Looks great. Went thru a pretty severe storm and only had very minor water get thru "
By Mark T. - OH
" Interestingly, my review is much the same as all of the reviews I read prior to my purchase. The Cover I bought performs exactly as advertised! It installed in just a little more than 1 hour. It is in fact weather proof, at least based on several trips to the car wash. I have yet be on the road in a rain storm, but have no reason to believe the performance will change. The cover seems well built and I expect it will last the live of my new 2021 Honda Ridgeline. BTW I spend numerous hours researching Tonneau covers. This is the only one I found without significant numbers of poor reviews. And the Ridgeline Owners Forum had numerous successful installations. "
