Overview
A clamp from Rolin sized at 4-1/2 inches and weighing 4.77 kilograms, close to 10.5 pounds. That is heavy for a clamp this size, pointing to a solid cast construction rather than a lightweight frame.
The 4-1/2 inch figure most likely describes jaw opening or throat depth rather than overall length, though the listing does not label it precisely. Paired with a weight near 10.5 pounds, this reads as a heavy duty clamp built for holding force rather than a light spring clamp.

Who it's for
Fits workshop use where holding strength on a 4-1/2 inch opening matters more than weight, such as woodworking or metalworking clamping jobs. Less suited to anyone who needs a light, portable clamp for quick or repeated repositioning.
Strengths and trade-offs
Drawn from this product's published specifications.
- Solid, heavy build suggests strong holding force
- Sized for real workshop clamping tasks
- Heavier and less portable than a light clamp
- Exact opening dimension not clearly labeled
Performance notes
Clamping force generally scales with frame mass and screw thread size, so the 4.77 kilogram weight here points to a frame built to resist flex under load rather than a lightweight design. That tradeoff means more secure holds on a workpiece, at the cost of being heavier to move around than a small spring or bar clamp.
