Overview
Weighing in at 5.1 lbs, the Olympia 38-604 clamp is built for holding workpieces steady during cutting, drilling, or glue-ups rather than light craft use, per the listed specs on file for this tool.
Clamps in this weight class are typically used in woodworking and general shop assembly, holding stock against a bench or squeezing joints while adhesive sets. The catalog entry for this ASIN does not include a seller description, jaw opening, or throat depth, so buyers who need an exact clamping range should confirm it against Olympia's published spec sheet before ordering.
