Total Access. Patented Security. Ultra Protection. The RealTruck(R) UnderCover(R) Ultra Flex hard-folding tonneau cover is built stronger and more durable, engineered for heavy-duty use with a sturdy, premium-grade matte black aluminum surface and a high-density polymer core. Its low-profile design sits nearly flush with the bed rails for a sleek appearance and up to 400 lbs. of weight capacity (evenly distributed). With ultra details, inside and out, the Ultra Flex's underside looks just as good as its top. The smooth, matte black finish delivers a refined look, while the exclusive soft-impact underside adds a padded layer of protection for shifting cargo. The Ultra Flex fits tighter to keep water out. Upgraded seals and all-new tight-fit clamps provide state-of-the-art weather protection, keeping out water, dust, and debris—even in harsh conditions. Security is a hallmark of any high-end tonneau cover, and the Ultra Flex delivers. With a patented rail and clamp system featuring automatic slam latches, the cover automatically locks down every panel when closed to keep gear secure and out of sight—that's patented security you can trust. The RealTruck UnderCover Ultra Flex hard-folding tonneau cover delivers 100 percent bed access—all the time. Simply fold the cover to the cab, secure it in place, and safely drive with the cover fully open. When closed, the slam latches reengage automatically. Installation is fast and straightforward with UnderCover's all-new click-in design. The redesigned Tip-and-Click mounting system requires no tools, no hassle, and installs in under 30 minutes. Proven for extremes from Alaska to Florida, Ultra Flex has been tested in harsh conditions ranging from -40 to 180F and up to 95 percent humidity. It's also been tested for 7,500 hours to reliably perform for over a decade of driving. Backed by a 5-year warranty, the Ultra Flex is tough enough for the job site, sleek enough for daily driving, and secure enough to protect what matters.This Part Fits:

NOT FOR PLAYING CATCH.
Color: Blue
This toy is quite heavy, making it good for a chew toy or for fetch, but not for catch. It could very easily injure your dog as it damned near did mine.

Durable bone that you can add a spreadable treat to
Color: Blue
Our German Shepherd was 4 months old when we purchased this. She’s going to be 6 months soon. She has been teething really bad. We wanted some way to sooth her pain. This product was just what we needed. We put it in the freezer with some peanut butter in the center on both sides. Once frozen we give to our puppy. She loves it. When we open the freezer she recognizes the ziplock package that it was delivered in which we store it in our freezer. She jumps around until we give it to her. She loves it and it keeps her occupied for a while. It is very durable. I did not notice any smell when we received it. It does not make any noise. The plastic material is safe for animals. To clean I put in the dishwasher. The only reason I did not give it 5 stars is because sometimes the peanut butter gets stuck in it and may need to go through the dishwasher twice which is not a big deal. Or you can hand wash it. I found the dishwasher was best for us. You do not even have to put anything on it, but our pup likes it. I would recommend to others.

Durable construction, including squeakers!
Style: Snake
This is the absolute best toy I've found. My dog is a 40 lb staffie who loves to play tug and chew. I'm used to toys lasting one day to one week and this one lasted about four months of almost constant daily play. The squeakers finally collapsed, so I'm buying my second one. I wish they would embroider the name of their brand on the toy because I forgot what the brand name was and it was hard to find again. Thankfully, I combed through my purchase records and finally found it. This brand definitely is my go-to for durable toys from now on!

Very nice, LOUD toy
Style: Crocodile
My parents' dog had the shark version of this toy already, and I looked to see if there were any other versions of the same toy. I found this crocodile. This thing is hysterical when he plays with it. I think each squeaker makes a slightly different sound, so you can hear him switch from 1 part to another. This is not for you if you like quiet. It is very loud but our dog doesn't like toys that don't squeak. The shark has held up for along time, and the crocodile is doing well so far. He's pretty rough on his toys, but he hasn't torn these or broken the squeakers. The fabric is soft, and it's well sewn. There's no stuffing in the body or limbs, so small holes don't really matter. It's big enough for larger dogs (ours is 45lb). The price was very good for a large toy that's high quality.
