1/4" Drive Socket Extension

This Wiha Tools socket extension fits a 1/4" drive and accepts a 1/4" socket. It is designed for technicians who need extra reach in tight spaces. The 3-15/16" overall length adds leverage without bulk. Professionals and DIY users working on electrical panels will appreciate the insulated design.

Insulated double-layer grip

The red-over-yellow insulation provides visual wear indication and protects against shock up to 1,000 V AC and 1,500 V DC. Installation is simple: push the extension onto the ratchet and socket until both lock. The chrome finish resists corrosion and wipes clean. No special tools or torque settings are required for assembly.

1,000 V AC voltage rating

This single specification determines suitability for live electrical work up to the rated voltage. The extension is made from alloy steel with a chrome finish and meets California Proposition 65 labeling requirements. Buyers who need higher voltage ratings or non-insulated extensions for general mechanical work should choose a different product.
