BOWSEN 16FT Heavy-Duty U+O Ring Universal Garage Door Bottom Seals Weatherstrip Rubber with Aluminum Track Retainer Kit

Installation overall was an easy couple of hours one cool afternoon.Aluminum bottom plate pieces with T-shaped grooves for the flexible seal are nicely machined and rigid. My large single garage door was not quite as wide as the 16 foot seal package I'd ordered, but the metal was easy to trim down to suit with a hacksaw and the seal with a large pair of snippers.Levered the seal into the T grooves with a plastic car trim panel tool I had on hand. There's a fair amount of wiggle room such that about every inch down the seal simply pressing into it saw it softly snap snugly into place.The only ding for me was the self-tapping screws. A few managed to strip the metal and spin freely, which necessitated pulling those out in favor of some wider ones. Not a huge deal, they appear to be overall doing nicely to secure the metal plates to the roughly A-framed sheet metal on the bottom panel of the garage door. They do jut upwards some but with the surrounding metal you'd be hard pressed to fall onto them and get jabbed (some scrap styrofoam would nicely cover the protrusions in case of wayward pets or toddlers).After adjusting downward extent of the door closure on the opener, there is now a lot less light intrusion and thus a significantly better seal than the one it replaces (which was inferior in that it had just a few inches of the relatively rigid tubing at either end rather than across the entire length of the seal).Photos show the installed seal with garage door fully open (note angle from horizontal in red), the disposition of extra seal in extra length of aluminum rail, and how I positioned and used the trim tool to snap the seal into the grooves.

Super easy to install, i got a little help from my wife, that tube inside was kinked during shipping but over time it got unkinked and now it seals to the ground perfectly fine. I recommend this over the normal seal that comes with garage door

Good product at a good price

So easy to replace.

Good product, easy install with a few hand tools. Seals properly. Just be aware that you may have to recalibrate your electric garage door opener's closing tolerance as the thickness of the rubber seal will cause your door to sit higher than normal. The adjustment was an easy fix and the seal works well.
