Thermwell Y3750 1/2-Inch x 37-Inch Vinyl "Y" Shaped Storm Door Bottom Replacement Insert For Aluminum Storm Doors, Gray

If you have the "Y" shaped strip on your door, 1/8" across the top, 1/2" high, then this is the one you want... see photo.It slid right in there, super easy to install. Will it hold up? I don't really care. Now I know which one to get, and if I have to buy it every year or two, or maybe buy several at a time, I can live with that.Please note, this won't provide a perfect seal under the door, but it's better than nothing.

Sealed my floor sweep on the storm door. You have to match configurations. Take a look at your old sweep's profile. It is either the shape of a "J" or a "Y". You have to order the correct one in order for it to work.

I reviewed after buying in 2020, updating. It hasn't been quite two years and I have to replace. The strip began separating and hung, and became very stiff. I do live in a place that is extremely hot for many months, cold in a few. I hoped for a little more longevity, but, it is a simple piece of thin rubbery material. Amazingly, our previous one may have been at least fifteen years old. The new one fit fine, just very tight as last time. I should have checked my old review to see how I'd gotten it to slide--Soap water. Soap water is definitely the best. Look at my photo of insertion, and you won't need anything but a few minutes of patience. Pull with one hand, push with the outer. It may get tugged and stuck just by pulling. I hope to be out of here before I have to replace again, but if not, I might try to look for another brand. It's fine if you don't mind frequent maintenance!

Ordered this door seal as my local building supply stores no longer carried it. It was exactly what I needed.

The Frost King weatherstrip is very durable. I used it on the bottom of an Andersen/Emco storm door (“Y” channel strip). I did have to trim about 1/4” off very carefully due to it catching on the bottom sill. I like it better than the one Andersen manufactures as it is a stiffer grade. The product arrived quickly, packaged well and no damage.

Nice keeps bugs out

Although my old strip was measures to be what this new stop says it is the New one fell out of the slit it is supposed to fit. I cannot find a stop with a different... the size that would stay in place.

This was an exact match for the worn out one. Good product for the price.

This is 1/8" thick and slid into the groove channel easily. It is 1/2" high. My only wish is that it was 5/8" wide but it still fit nonetheless. It arrived on time and it did the job. Reasonable priced. It resolved my issue of repairing my obsolete aluminum storm door sweep. Thank you.

Exactly what i needed

Easy to install - spray storm door grove with silicon spray and oil the top of rubber ( Y shape ) with motor. oil. Feed rubber in the storm door grove - pull the rubber at one end while inserting the rubber to the groove at the other end. Easy to installCost of rubber is a bit pricey

Do not buy this product! It was easy to install but it only lasted 3 days. The product is made of vinyl plastic - once it gets cold it breaks easily. Do yourself a favour, look for a product made of silicone.

The original's rubber height size is nowhere to be found for my ancient door sweep. This "Y" shaped one slide in perfectly and I only needed to lower the sweep a bit. Saved me from buying a new storm door because not only is the original vinyl insert no longer available even it's complete sweep isn't due to the door's age.
