These clamps are great for a variety of clamping jobs. They are small and light, exceptionally strong and very durable. They can clamp any material up to 2" thick, are quick to remove, and can re-clamp the same thickness without having to readjust the thickness. Ideal for the machinist or carpenter. I've been using the larger ones for years and am completely satisfied and know I'll get the same great performance from them. No damage with self-adjusting swivel pads, they work great!
