YaHoGa 2PCS #10 30 Inch Separating Large Plastic Zippers Black Tape with Double Pull Tab Slider Heavy Duty Zippers for Sewing, Sleeping Bag, Boat, Canvas, Cover, Trampoline, Dog Bed, Tent (30" 2pcs)

Used on additional canvas for boat, perfect zipper fit with previously made professional external curtains. Well made zippers and easy to work with and sew. Recommended

Awesome high quality zipper at a fabulous price.

It's definitely a thick and durable zipper with a really long sized track. I used it to sew a woobie from end to end and make it function into a folding blanket. It was easy to use as the zipper tracks have a lot of fabric for you to sew into which made it work perfectly. The zipper is double-sided so you can access it from inside or outside.

Overall they feel pretty sturdy and match the quality of other good project zippers. However I assumed it came with an adhesive option, it does not.

Worked great for my project

We've had a shelter out back that has held up to numerous WNY winters - until this year when the zipper broke. Come to find out the company charges almost as much for a replacement door section as it does for the entire shelter! Bought this zipper and just adhered it to the broken zipper and for under $15 fixed a nearly thousand dollar problem!!! It is durable, dual zippered (can access zipper holds from inside and outside) had ample room on fabric sides to adhere to existing material. The material is weather friendly and will hold up to winter exposure. Great product!

Very pleased with this exceptionally long zipper. I used this for a boat canvas project where it flapped violently at times in the wind. It amazingly survived the season. Two of these were used in series to create a sleeve as a sun cover for my headsail. I can't say anything other than I am very pleased, even with UV resistance so far. Please note: Zippers come in two styles, one opens fully like a jacket like this zipper, and the other type expects the end to be sewn together. Buy the correct type. The cut to length type with a coil zipper as opposed to individual teeth is supposedly less resistant to UV as the thread holding the teeth is nylon. Measure and get the lengths correct. don't expect to cut and have an easy time.

I have decided to replace the gazebo zippers. The zippers that are on the curtains were not heavy duty-thus I was disappointed/concerned. A year later, I need to replace 6 72" zippers. Heavy duty is important! I purchased 2 different 72" zippers to see which had the best quality. ☆ this zipper surpassed the other zipper that came 2 per package. I am glad I test my theory and found it correct! If your looking fo a heavy duty 72" (or shorter) Trust Me, buy this one. It tried to focus in on the zipper so you can see the size difference of the "teeth". In many ways folks say, "size doesn't matter?!" Well I say it does Matter!!!

I sawed these into my portable greenhouse - since it came with very weak, flimsy zippers that fell apart quickly. Really great zippers! Great quality, fast delivery. Thank you!

Arrived in good condition, used to replace zip on sleeping bag, did the job, need to be good at sewing though, sturdy, plastic teeth and zip, fair price.

It was for a tent trailer. Make sure you buy the one that is too long - I cheaped out and bought a 48" - I needed the next size up. It zips like a hot dang and kept the wind out while we slept. Next they need a way to keep the cold out. It was 2 degrees C - even for a Canadian... that's cold

Used this zipper to make a stack pak sail cover for my boat and it is very durable and tough.

A little pricey but not available in stores near me. Exactly what I expected, good quality heavy duty zipper.
