All-Weather Design

BlackMax Adjustable Studs

The replacement offset snap studs on the Extang tonneau slide along the rails, and they can be removed and rotated to ensure a proper fit in any climate. Cold weather causes vinyl to contract, and heat causes it to expand, so the fit of any vinyl tonneau cover will change according to the outdoor temperature. To make sure your tonneau cover always fits properly, the tonneau uses these adjustable studs so that you can fine-tune the fit for the season.

Set the studs in the "High" position in cold weather and in the "Low" position in warm weather. When in the "high" position, the cover is given a bit more slack to allow for the natural contraction that takes place when vinyl is exposed to cold temperatures. The "low" position takes up any slack, ensuring that the cover stays taut even as the vinyl expands.

Overall great replacement snap for a older tonneau cover, easy to install and the ability to change the snap for cold and warm weather is a nice feature for proper fit.


you guys are great and very professional, I needed help on ordering a tonneau tarp,it was not in stock but I received a call to let me know that the vendor will ship it as soon as possible...the communication was great


Perfect fit!


didn't fit my truck properly, but used them anyway


Worked perfectly!


I got a pack of 28 clips for less than $xx.xx which is a pretty good deal compared to other offerings, and shipping was both cheap and quick too. Overall, I enjoyed using this website to purchase parts, and recommend it to anyone who might be on the fence a little like I was.

Theyre still working and keeping the tonnue cover on tightly. Its a product that you buy once and dont have to worry about again.

This product works as it should..No problems with it.. In fact, after a few days of ordering it.. etrailer sent me an email asking if I had received it and how do I like it... I had not received it, they promptly answered my email with a tracking number and all the information i needed....I would definitely order from them again...Great experience ..Thanks


I needed some replacement snaps for my sons tonneau cover and etrailer had the best price. I received the snaps in a timely fashion and they are exactly as described.

Always a good experience ordering from etrailer. Products are alway first class along with the shipping
Ordered these snaps and was here in no time


When I replaced the tonneau tarp, I replaced the snap clips around the rear of the frame, where they were used the most - Same or better quality then the ones on from 2004!


I ordered snaps and a corner piece for my Tonneau cover and I received them in a timely manner and they were exact replacements for what I needed. Price was also very reasonable


Very close fit for an obsolete setup. Worked fine with minor mods. Saved replacing entire tonneau...


Didn't think I'd find these for my old snap on bed cover but here they are :)


Snap replacement kit helps to keep cover on tight replaces old worn snaps that doesn't make cover stay put
