Overview
Listed simply as model 201B and weighing 17.5 ounces, this clamp's other specs, jaw opening, throat depth and clamping style, are not given in the source listing.
With limited spec detail beyond weight, the practical read on this clamp comes down to size and heft. At 17.5 ounces it sits in the range of a small to mid size hand clamp rather than a heavy duty bar or pipe clamp, which tend to run several pounds.
- Model number 201B
- 17.5 ounce weight

Who it's for
Buyers looking for a light, compact clamp for general shop or craft use are the likely fit here. Anyone needing a heavy duty clamp for large stock or high clamping force should confirm jaw opening and clamping pressure before buying, since neither is listed.
Strengths and trade-offs

Performance notes
At 17.5 ounces, the 201B is light enough for one handed placement, pointing toward general purpose or craft use rather than heavy structural clamping where bar or pipe clamps with more mass and leverage are typical.
