Overview
Weight tells most of the story on the Groz 35805: 3.42 kilograms packed into an 18 inch frame, the kind of heft associated with cast metal bar clamps rather than lightweight spring clips.
At roughly 7.5 pounds for an 18 inch tool, the 35805 carries more weight per inch than a small spring clamp, consistent with cast metal clamps built to hold work steady under real pressure. Groz is known for hand tools including vises and clamps, and the dimensions here fit a bar clamp footprint, though the exact clamping style and maximum jaw opening are not stated in the listing.

Who it's for
Woodworkers or metalworkers after a solid clamp in the 18 inch range for glue ups or fabrication line up well with this listing. A lightweight spring clamp buyer, or anyone needing a stated jaw opening confirmed, will want more detail than is given here.
Strengths and trade-offs

- Solid weight for workshop grade clamping

Performance notes
The 3.42 kilogram weight for an 18 inch tool suggests solid cast or forged construction rather than a lightweight plastic clamp. Dimensions of roughly 18 by 6 by 2 inches fit a bar clamp footprint, but the listing does not state maximum jaw opening or clamping pressure.
