Overview
The Bulldog PO-25 is a small clamp measuring about 2 by 1 by 3 inches and weighing under an ounce. Those figures point to a compact spring clamp rather than a full size bar or C-clamp.
Bulldog is a name associated with small spring clamps for craft and light hobby work, and the size and weight here fit that category closely. This isn't a clamp for structural woodworking, more a light hold for glue lines, hobby projects, or small parts.

Who it's for
Good for crafters, hobbyists, and light woodworking where a small, low pressure clamp is enough to hold thin material or a glue line steady. Not suited to anyone clamping thick stock or needing real holding force.
Strengths and trade-offs
Drawn from this product's published specifications.
- Small and lightweight for easy handling
- Fast to apply for light holding jobs
- Not suited to thick or heavy stock
- Low clamping pressure compared to bar clamps
Performance notes
At under an ounce and about 3 inches at its longest dimension, holding force comes from a small spring rather than a screw mechanism, which limits pressure but makes it fast to apply and release for light tasks.
