    • Check The Track Slot First
Size: 37" Style: Y- Shaped
This review is of the M-D Building Products gray vinyl "Y" shaped storm door bottom seal, ASIN B000I1CDJC. I found that the product does exactly what it is supposed to do, but I had some difficulty getting it into the track holding the seal. I was fortunate that my door had a removable bottom piece held on by only two screws. One of my doors has the track as an unremovable part of the door. Being able to put the strip in a vice between two pieces of wood greatly simplified the job. After removing the track, I had to free up the crimped ends holding the old seal. The door manufacturer had made the end crimps needlessly deep, but screwdrivers, some punches, a hammer, and patience freed up the track ends without causing damage. There were a few other places where the "Y" slot had been bent so these areas also needed some work. If the track is free of all bends into the "Y", the new seal will slide through easily. It was very beneficial to cut off a 1/2" piece of the new seal to be used as a test gauge. This was used to check the full length of the "Y" slot to ensure that the new seal could be installed without difficulty. I did find some more tight areas in the track although it did not visually appear to be bent. After the test piece would slide all the way across the track, I lubricated the seal "Y" and the track slot with plenty of Dawn dishwashing soap before pulling in the new seal. I used more than a few paper towels as it was messy. I staked each track end to hold the new seal in place, although not nearly as deep as what was there originally, so that it would be much easier in the future to put in another replacement seal. M-D has made a simple but very useful repair product. ... show more

    • Good replacement seal for trim that requires slide in
Size: 37" Style: Y- Shaped
My door is probably 15 years old at least. I had to take off the bottom trim that slide over the bottom of the door and then pry open one end of the v notch a little bit with a flat blade screw driver. I put some soap on the rubber to the help it slide it easier. It does require cutting to match your door, so make sure to measure or mark where you need to cut. When looking around for a replacement seal make sure you look at the end and see if it is a "Y' , "T", or "V" shape. I couldn't find this in local hardware stores, so amazon was the place to go. Satisfied with it. ... show more

    • Functional repair part.
Size: 37" Style: Y- Shaped
This is a piece of extruded rubber sealed into a plastic bag. The price is unreasonably high and there are two per door. Would give 5 stars except for the price. Installation is relatively easy, but necessitates un-bending a crimp in the aluminum door bottom extrusion, and then re-crimping afterwards. And, once installed, the replacement works like new. ... show more
