Overview
Measuring just 4 by 1.25 by 1.25 inches, the Klein 32378 is built as a stubby style screwdriver for reaching into tight enclosures where a full-length driver will not fit.
At just 4 inches long, this sits closer to a stubby driver than a standard length tool, and the 1.25 inch width suggests a handle built for grip rather than a slim profile. Klein Tools built its reputation on electrician grade hand tools, and this compact size points to a driver meant for panels and other close quarters work.

Who it's for
Good for electricians and technicians working in tight enclosures or behind panels where a full-size screwdriver cannot reach. Not the choice for high-torque work where handle length adds leverage.
Strengths and trade-offs
Drawn from this product's published specifications.
- Compact 4 inch length fits tight spaces
- Wider handle profile aids grip
- From Klein Tools, an established trade brand
- Shorter length means less leverage than full-size drivers
- Sold as a single tool, not a set
Performance notes
The short 4 inch overall length trades leverage for reach into confined spaces, while the wider 1.25 inch handle helps offset some of that lost torque with a firmer grip.
