The #5 zipper with double pulls was exactly what i needed for my canvas winter tent project.
sewed up a bunch of Bag Buff Mountain Flyer fanny packs over the weekend and each one had one of these sliders!
I picked up some along with cool zipper for a bivvy and a tent I am making. It is very easy to cut, sew, and finish. Getting the sliders on a #3 is a little harder than a #5 in my experience because the system is a little less stiff, but not difficult by any means. RBTR has been stellar regarding acknowledgement of special requests I have placed on my order and have been very helpful in answering questions I have had about materials and construction techniques. Excellent service with excellent materials at a good price.
I couldn't be happier with these folks ! Great customer service and timely shipping . Thanks !!
I had never used a coil zipper before and it was real easy. Just sew it on and your good to go. Pretty much that simple. Plus YKK is the best.
