  • Dual orange and yellow layers show wear at a glance
  • Tested to ASTM F1505 for verified safety
  • California Proposition 65 notice included for compliance

Insulated Socket for Electrical Work

The Gray Tools MT15-I is a 15mm, 3/8 inch drive socket with a 12 point configuration. It is designed for professionals who work on live electrical systems up to 1000 V. Each piece is individually insulated and tested to ASTM F1505 standards for verified protection.

Upgrade from Non-Insulated Sockets

This socket replaces standard chrome or impact sockets that offer no voltage protection. The jump is worth it whenever a task requires confirmed insulation for 1000 V environments. A dual-layer coating uses an orange top layer over a yellow safety indicator layer that reveals damage instantly.

Limits of ASTM F1505 Insulation

The ASTM F1505 standard verifies dielectric performance up to the rated voltage but does not guarantee protection beyond 1000 V. Insulation integrity depends on the yellow indicator layer remaining intact; any visible yellow means the socket must be removed from service. It is not suited for applications exceeding the tested voltage rating.

Questions about this item

Will the 15 mm hex and 3/8" drive fit my existing ratchet?

The socket has a 15 mm hex opening and a 3/8" square drive, so it fits any standard 3/8" drive ratchet or breaker bar.

How do I install it on the ratchet and what step is often missed?

Push the square drive onto the ratchet anvil until the ball detent clicks; the missed step is inspecting both yellow and orange insulation layers for cracks before every use.

When should the socket be replaced?

Replace it immediately if the yellow safety layer becomes visible through the orange layer, if insulation is cracked, or if it fails a 1000 V re-test per ASTM F1505.
