Notched sections grip corners and round objects securely, while smooth surfaces prevent marring delicate materials. Heavy plastic construction provides surprising clamping pressure without the weight and cold transfer of metal clamps, making them comfortable for extended assembly sessions.

The slide beam doubles as a measuring guide with inch markings, eliminating the need to set down the clamp and grab a ruler mid-project. This matters when you're positioning multiple pieces and need to maintain consistent spacing. Plastic construction won't damage finished surfaces or leave metal marks on light-colored woods and papers.

Available in two sizes to match your project scale: small 3½-inch clamps handle jewelry boxes, small frames, and model work, while 7½-inch clamps secure larger assemblies and multi-part constructions. Each package includes two clamps, giving you a matched pair for balanced pressure across joints. Keep both sizes on hand for the flexibility to tackle anything from miniature shadow boxes to substantial mixed media assemblies.
