YaHoGa 80cm #20 Super Large Separating Giant Plastic Zippers for Sewing Tents Coats Overcoats Boat Cover Canvas Heavy Duty Huge Resin Zippers (31" Black)

Goooood quality.. i used IT to mske a 20’ patio Romsn shade - the zipper holds A 14’ tarp & 6’ tarp door closure!!! PERFECT HEAVY DUTY

It’s a great zipper I got it to replace my old metal zipper on my tent trailer. Works so smoothe and it’s easy to zip best part is it cost 1/3 the price. Great value great zipper

This was a good zipper fix for an outdoor greenhouse. The zipper is plastic but durable. It has fabric on each side to attach to whatever material you are attaching to.(I used fishing wire with a leather hook to push through the zipper fabric and greenhouse plastic to attach and it worked well.)It was affordable and a good deal.

Loved the visual impact of this oversize zipper, used it in a knitted vest. Looks great, but easy to tell it's not designed for garments. 31" minimum length and doesn't look easy to adjust. No top stopper on one side, so the pull can come completely off when the two sides are separated. Maybe this is to facilitate cleaning items without the pull getting damaged? Also, there's not much tension or a stopper tooth, so there's no resistance to it opening with movement or any stretch from the fabric, or just gravity. I'm sure it's great for what it's designed for. It might deserve 5 stars, but I'm taking one off because I can see the pulling open and pull coming off issues affecting usefulness in any situation.

Sewed on great. Works as it should. No more broken zipper on my bibs! This zipper is heft! I mean hefty!

I bought several of the zippers installing them on my boat canopy just for them to fail before I ever hit the water the problem is the zippers are extremely heavy and material but very poorly engineered or zipper opens up or expands after you zip it acrossUpdate, zippers have all fallen apart 11/26/24

Used to replace a typical nylon zipper with metal slide on a bag in a marine environment — where larger-toothed plastic zippers fare much better. Very happy.

Not sure what I was expecting but I was a little disappointed in the plastic quality of the zipper. The teeth were standard nylon plastic like you’d expect but the zipper felt cheap and lightweight. I still used it but I take extra care when zipping as I worry the zipper will break. Overall not a bad product if you’re after a certain aesthetic, but I wouldn’t put a lot of trust in the integrity of the materials.
