Greenhouse Snap Clamps 3"

Keep your row covers, shade cloth, greenhouse film, or netting snug and secure with our Snap Clamps – the go-to fastening solution for market gardeners and homesteaders who rely on tubular framing for season extension and crop protection.

Designed to fit 1 ⅜” outer-diameter tubing (Haven, Classic Caterpillar, and Gothic Caterpillar Tunnel Bows), these clamps snap tightly into place to hold fabric without tearing or slipping, even in wind and rain. Whether you’re building low tunnels, hoop houses, or trellis systems, these clamps offer a reusable, no-fuss alternative to squeeze clamps, zip ties, wire, or bungee cords.

For growers who build their own solutions. Whether you’re extending your season or protecting against pests, these clamps are an essential part of your farm toolkit.
