Gray Tools MT14-I 14mm 3/8" Drive 12 Point 1000V Insulated Socket

14mm 1000V insulated socket

The 14mm 12-point socket fits a 3/8 inch drive and is individually insulated and tested to ASTM F1505 standards. It provides user protection for up to 1000 V during electrical work. An orange top insulation layer covers a second yellow layer that serves as a visual safety indicator. This tool is intended for professional technicians working on live or potentially live equipment.

Sustained electrical protection

The dual-layer insulation maintains its dielectric properties during extended use on energised components. The yellow indicator layer reveals damage immediately if the orange outer layer is compromised. Each socket undergoes individual testing to verify compliance with the 1000 V rating before it leaves the factory. This construction supports reliable performance throughout long maintenance sessions.

ASTM F1505 standard limits

The ASTM F1505 standard governs the insulation testing and voltage rating applied to this socket. Protection is certified for up to 1000 V under the conditions defined by that standard. The product carries California Proposition 65 warnings for chemicals known to cause cancer and reproductive harm. Users must inspect the yellow indicator layer before each use to confirm insulation integrity.
