🔳 Thermwell RV/36H 36-Inch Gray Vinyl Insert, 1-7/8" x 36", Grey Review

A bit tricky to install in cold weather. I would have preferred a plain top to grommets because the door is harder to open and close, but in a pinch it will work until we replace the entire sill and door.

Although it was unfolded flat on the ground before installation, it curved into a giant C. I managed to install it. better.

Came folded but not tight. It lay flat right out of the box. However, it is in the form of a curve. The inside is shorter than the outside. It cannot be straightened because the longer outside is curved. This is inappropriate.

The original door insert was 1 3/4" wide, but a new replacement cost more than double that. I took a chance and hoped it would still be installed and maybe provide a tighter seal at the bottom of the door. My game paid off as it installed like the original and was easy to build.

I needed a vinyl sill insert as the one that came with my MD building products was too tall for the door to close easily. This one from Frost King was lower and fitted perfectly. Cut to size and ready in a minute or less!

The insert supplied has grooves. Based on customer photos, I'm not the only one getting combed inserts. However, the photo of the product shows an insert with a smooth surface on both sides. It doesn't work for us because when closing, the dorr pulls the insert out as it's clinging to the ridges. There's a reason the old one was smooth (and no, it's not that the old one originally had ribs that got rubbed off, you can say it was perfectly smooth).
