ZIP-UP Cloth Zipper Door - 84" x 3" Peel & Stick Dust Barrier Zipper with Self Adhesive Backing & Air Tight Seal - Twin Pack - ZIP7.3BCL

Works great for my boathouse door.

I have been renovating my bathroom and while I performed removal of old tile, walls, cut concrete and installed mud pans, drwall etc. with the existing bathroom door attached to retain dust, I used this zipper last when I had to remove the master door to make way for a new barn door I made. This originally was a traditional door, with the hinges and wood frame. Since keeping the old frame would not look right/good, I ripped out the frame, then finished it with drywall and bullnose corner beads. Drywall work creates immense amounts of fine dust, even if you use a shop vac like I did to control it. Since we still slept in our bedroom, I used this in an effort to control dust. Who knew it would actually do a better job than the door...Since I had to finish the master bedroom side wall surrounding the door, attaching plastic to the existing wall would not do. So, I built a 2x4 frame that screwed into the wall above the door and at the baseboard as well (easy to fill a few screw holes). It extended 2' outside the door frame and 2 1/2' into the bedroom. This gave me plenty of space to install the drywall, corner beads, joint compound and sand, also giving me room to blend the wall texture with the old. After I built much of the frame attached the thicker 4 mil plastic from Home Depot. I did this first by laying the plastic on the ground, marking the line, then attaching the zipper. Once attached, I put it up and it worked perfectly. It has been up about two weeks and will come down this weekend as I am complete with this and other "dusty" work.Items of note.I did a bit of research on these zippers, seeing others with reviews of adhesion problems. I had worked with the very tough/nice 4 mil HDX plastic from Home Depot before, so I knew tape; not just painters tape, but packaging and masking tape tends to have issues staying on if any stress is involved, so I wanted something very sticky. I settled with this thinking worst case I would strengthen with duct tape, but as I applied it, I knew I would not need it. This tape is very good with no adhesion problems at the time, or after two weeks.I was also concerned about the zipper itself being tough enough and sealing in the air. It has proven tough, and if you wet your hand in a positive airflow like I had in my bathroom, you may feel a hint of air, but my entire plastic room ballooned, surprisingly hard BTW, so there was pressure and not a hint dust coming through. It made me realize my door must have allowed much dust through... Regardless, tape still held well, and the fabric was strong with zero chance of failure. Also, this does come with 2 zippers, but using that configuration, I knew the bottom flap would allow much of the air to escape, hence be unable to contain dust. So, I decided to use one zipper. I expected unzipping and getting through he door to be tight, but I had all equipment in the bathroom and just needed to get myself in and out while I awaiting the drying of mud over several nights, etc. It worked perfectly, but if you have to get equipment or supplies in and out, you may want to use both and come up with a wood flap on the bottom to keep it closed.As for install, I don't recall what the instructions said, buy I drew a line, had my son hold one end tight, while I removed the backing, slowly pushing down the tape of the zipper as I went. It worked well, but the tape is so sticky, you do NOT want to remove the backing at once. I followed that up with rubbing the seem up and down with a piece of PVC and all was well. I immediately put the plastic on the frame I just built, then cut the plastic under the zipper and it was perfect.

Fantastic fabric mesh adhesive sides and good quality metal zipper head. No need to double up the sticky sides with additional duct tape. And sold at a great price compared to my local ‘big business’ hardware stores. (They were selling a lower quality tarp-plastic version of the zipper for almost $50. Insane)I have no complaints. I’ve been using it for a month and it hasn’t peeled up anywhere. Very nice. Very good price for value.

I had seen these being used in businesses but had not looked at them closely. I was having some work done on my house after some flooding. The team came in and set these up while I was in my study. When I got ready to leave, I studied the inside of the 'door', unzipped it, and studied the outside. Air-tight, is a bit of an overstatement, dust tight is more realistic. The way they were set up was with painter's plastic sheets and tape. Based on my time spent in my study, they seemed very effective, much more effective than just closing the door, the door leaks at the top, bottom and all sides.I was doing some work on my daughter's house and decided I needed some of these to keep the rooms that were done clean. So I ordered a set. That same day, while I was at the hardware store, I found a painter's canvas drop cloth with plastic on one side. It was 8 feet long and 4 feet wide. A light came on, the zippers are 84" if I cut the drop cloth in two, I would have two at 96". I bought the drop cloth, cut it down to 2 pieces 96" long, then split the center of the 4" to 86", leaving 5" on each end.When the zippers arrived, I sewed them into the drop cloth, making sure the plastic covered over the zipper. The bottom 'tail' can be taped to the floor and the top 'tail' to the wall. When the zipper is closed, the tongue is at the bottom. When I am through with one door, I take down my cover, taking care to keep as much dust as possible trapped as I take it down. I take it outside, put it on my makeshift clothesline and sweep off the dust. Before I use it again, I blow it down with a leaf blower. The time invested in making these has been recouped, I have used each of them at least 4 times each. The money invested, well time is money, I am ahead of the game.

Works perfectlyRemember to orient split at the bottom … instructions could have said this
