Overview

This Rubbermaid 3D30-LW-WHT clamp weighs just 1.4 ounces and measures 8.5 by 6 by 1 inches. Its flat, light profile reads closer to a household clip than a shop clamping tool. It holds a 4.6 star rating from 283 reviews.

Rubbermaid is best known for storage containers rather than trade tools, and this item's thin 1 inch depth combined with a 1.4 ounce weight fits that pattern more than it fits a bench clamp meant for woodworking pressure. Treat it as a light duty clip suited to household use rather than shop grade clamping.

Who it's for

Suits household use where a light clip or clamp is needed to secure a lid or lightweight item. Not built for woodworking or metalworking pressure, given its featherweight, flat construction.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out

Very light at 1.4 ounces
Flat, compact footprint
Strong 4.6 star rating

What to check first

Not built for heavy clamping pressure
Thin 1 inch profile limits reach

Performance notes

At 1.4 ounces and 1 inch thick, the clamp has little mass or bulk to generate strong clamping pressure, which points to household or storage duty rather than shop tasks. Its flat 8.5 by 6 inch footprint suggests it sits against a flat surface rather than gripping a workpiece.
