Replacement Rail Snaps for Extang Tonneau Covers  

Updated 10/08/2026 | Published 10/21/2015

Question:

I have white plastic snaps that are attached to a metal runner on each side of truck. The metal buttons on tonneau cover snap into the plastic counterparts. Unfortunately, the cap at end of the runner fell of and a number of the plastic snaps slid off the runner and are lost. Need these plastic snaps.

It sounds like you are looking for replacement snap studs such as # EX2128 for Extang BlackMax tonneau covers, slide along the rails, and can be removed and rotated to ensure a proper fit.

We also have # EX7128 which are the same thing only for Extang Classic Platinum Tonneau Covers.

@JimM Unfortunately, it looks like these were discontinued and we sold out last set back in June. You could try contacting Extang directly to see if they have any more stock, but we will not be getting these anymore. Sorry I don't have a better answer for you.
