Prime-Line T 8658 Window Pile Weatherstrip, Slide-in style for 3/16 in. channel, Gray, (18 foot)

Exact replacement, works perfectly. Takes a little time to press into track if you don't have the option to slide into track because the risk of other issues. Just be patient and use a plastic tool like a plastic putty knife. Many state it does not fit, likely because it is not the correct one for your window.

I ordered this product as a replacement for an old worn-out pile weatherstrip in a slider window. I couldn't find this product at my local home improvement store, but it was on Amazon. I measured my old weatherstrip before I ordered, so I figured the 3/16 inch width would fit which it did very nicely. It does have the plain backing and not that saw tooth backing as I noted some reviewers mentioned. Also, it does not have adhesive on the back, but I didn't need that because my old weatherstrip fit into a groove on my window. I cut this Prime-Line T-8658 weatherstrip 22 inches long to fit in the groove on my window, after I had pulled the old stripping out. I started it in the groove at the bottom and used my fingernail on one side to seat it in the groove. It fit perfectly. The Prime-Line T-8658 has a thickness of .156 inches (5/32) and I wish that it would have been a little thicker like around .187 inches (3/16), but I think it still provides a seal when the window is completely closed. All in all I am satisfied with my purchase.

Did the job3/16 was the smallest we could findSome areas of the windows we could not slide it into the track. Ended up cutting the sides to get it to snap in.Sizzors did not work well to do thisBUT Big toe nail clippers with the strait edge did. But that took hours.

Used to refresh an old storm door. Unfortunately It didn’t just slide in mine, as there were little indents in the channels every 1/2 inch or so. I used the smaller wheel of a screen spline roller tool to press it in Along length and that made installing it much easier

It was the right style of product but not an exact fit (my piss poor measuring skills got me again!). I thought that I had the correct measurements - measure thrice, purchase once...

The tricky thing about wool pile replacement is figuring out what size(s) to buy—after all, the base of the old pile is still in the window and what pile there is, is worn. All I can suggest is to do your best to measure, then buy a couple different sizes, then purchase more of the size that works best. I started with 1/4” high pile, then opted for the .156” high. I almost wish I could have found something in between. Of course, the .156 could quickly flatten and negate the installation of fresh pile completely. Only time will tell. My old pile was crimped in place on both ends but removal was easier than I thought—just stuck a sharp awl into the end of the groove and wiggled on it until enough came out to grab with pliers. Don’t measure for the length you need-just hold some up edge to edge, mark with finger & cut. Installing the new pile was simple. Place bottom edge in first and push in upper edge with a flat head screwdriver, one ‘tooth’ at a time. I went over the installed pile with a screen roller to ensure it was all the way in. This seemed to solve my drafty window issue even if the window is harder to slide (for now?). It will probably loosen with time. Good product.

DO NOT PURCHASE THIS ITEM. 'Had to throw it away as the height, width, and body of this insulating material was wildly insufficient. Imagine shaving off one side of a really skimpy pipe cleaner and you'll get an approximation of the bulk of this weather stripping. However, shipment was very quick.

The plastic side that slides into the channel fits perfect but the felt is half as thick as the original. Will not hold glass tight and prevent it from incessant movement from wind or opening and closing. Sent it back in hopes of finding a seal with double the thickness of felt.
