M-D Building Products03541 17 ft. Brown V-Flex Weatherseal

I had last bought a pack of this stuff about 25 years ago for my last house. My new house would benefit from this weather stripping so I was glad I found the same product (in the same packaging! Ha; why change?). Cuts with a scissors or knife. Sticks well (do remember to clean the surface properly!). I expect to get 20+ years of use. Certainly a bargain and will fit almost any door frame without much effort.

I use this product for sealing a double sliding door with a "doggy door" inset section.The main doors are often used by people as well and it requires semi-annual replacement. Easy to apply very accurately provided you have a good eye. You get one shot--at least on aluminum--as repositioning greatly reduces adhesion at the second location. Clean perfectly removing any residue of previous adhesives and other contaminates.

I like this strip. It should be sold in 50 yard rolls. I reduced the stars for adhesion because it just isn't sticky enough. But I've found that a few smacks with an office stapler and you can forget the adhesion unless you are working with aluminum. Not sure what you'd do in that case. Maybe liquid nails or something like that?

I bought this for two doors that needed weatherstripping, but thicker weatherstripping options were to big for the gap between the door and the frame. This weatherstripping was thin enough to fit. Unfortunately, the material is a bit too flexible, and ripples along its length so there are spaces where air can get through. It’s better than nothing, but I think I’ll be looking for a better solution to replace this.

I have older, metal casement windows whose rubber gaskets (which kept rain and wind from entering between the window portion and the frame) had failed. Impossible to find replacements, and even the thinnest foam weatherstrip would prevent the window latches from pulling the windows tightly closed. This did the trick, good adhesion and thin enough when folded to allow for a tight close. Afraid to tell my neighbors who just spent thousands getting new windows! I used the product unfolded ( as it came off the roll) to stop wind penetration between the fixed and movable portions of my older metal sliding patio door. I can open the door, but when closed, the draft is gone! See photo. Less expensive on Amazon, but Home Depot online has it as well. I agree with others that I cannot understand why HD does not carry it in store.

Warning, this product is NOT suitable for doors. Also, the product that arrives doesn't match the description on the website. The product that arrives is called "M-D V-Flex WINDOW Seal -- For Use with Double-Hung Windows". It is intended to go between the window frame and window sashes. It was not sticky enough to stick between a door and a door stop.Probably okay for use with windows; for a wooden window, I'd put a staple into the wood at each end to hold it. NOT okay for use with doors.Also slightly irritating that Amazon doesn't take care to match the actual name of the product with the description on the Amazon website.

M-D Building Products 3/8" V-Flex WeatherstripThis product is easy to install. Some tips: clean the surface well and make sure it is dry before installing; measure well and pre-fit the weatherstrip before installing--the adhesive is strong and once in place is both hard to remove and does not stick as well the second time; leave the protective tape on the weatherstrip while measuring and bending--it makes handling a lot easier.Time will tell how long it lasts; the initial seal is quite good.Brown is only color for 3/8" weatherstrip; I would have preferred white

This cost ~2x the amount of the Frost King offering, and is actually more cheaply made. The material is much thinner, meaning it will wear out quicker through compression cycles. A couple weeks in and the spring action is noticeably diminished.

Product is very poorly made, cheap material, splits open on crease line, doesn’t stick no matter how clean the surface it is being applied to.I bought this product years ago from a hardware store and it is still working, it was much thicker and better adhesive. I don’t recommend anyone buy this.

Muy bueno como tapa-polvo

adhesive would not stick
