The best end caps on the market! I’ve searched many of end caps and these are the best ones that I could find. Most of them are like little plugs that just go in the end, but these are nice little ramps that make a smooth clean look that you can not worry about having something catch on the end of your E track. I hate to say it, but I did have to get my E track from somewhere else because I needed it in black and there was a little bit of a fit problem, but that was easily solved by trimming each side of the endcap that goes into the E track by 1/16” then it fit perfectly. If I ever need any more, I will definitely buy these.
