🛒 M-D Building Products 43824 Gray Vinyl Replacement Threshold Insert Seal - 36" L x 1-1/2" W: Buy Online Review

I was having trouble finding a replacement gasket to fit the deluxe MD sill in my area so I went to Revain and looked around and ordered them and they fit and looked great

Not sure if this is even a replacement part. I was happy when I discovered this replacement! Our old one was flat and leaked water in heavy rain. This replacement strip creates a new and tight seal between the transition and the bottom of the patio door. Just tear off the old slotted screwdriver, clean channels. Measure how big you want the new one to be and cut it off with a sharp blade. Then line it up with the channels and press it in with a rubber mallet or some elbow grease and voila! ☺

Perfect replacement and good quality so far. The original collapsed from the garage/laundry door sill due to foot traffic.

Matches perfectly with existing MD sill at a reasonable price. Major stores have stopped selling MD products in my area and their new brand does not offer a replacement Rubber sill insert on They want to sell you an aluminum sill assembly when all you need is a new rubber grommet I bought two from Revain and now I have a spare.
