These liner clamps, https://www.breezehoseclamps.com/breeze/liner/ with the stainless hex screw. They come in a box of 10 and I'd buy maybe six or seven different boxes of the smaller sizes if free shipping is offered for orders over $100. Here again I found one place that would ship only UPS for $19 instead of flat rate Priority Mail at $8. Anybody who buys these suggest a place to order them from at a good price? No not Grainger.
