7/8" 12-Point 1000V Insulated Socket

This 7/8 inch 12-point socket is insulated for live-line work up to 1000 volts. It features an orange outer insulation layer over a yellow inner layer that acts as a visual safety indicator. The tool meets ASTM F1505 standards and is individually tested. It suits electricians and maintenance technicians who need verified insulation on fasteners.

Verify Drive Size And Clearance Before Use

Confirm that your 3/8 inch drive ratchet or extension matches the socket drive. Check that the insulated diameter clears the specific fastener and adjacent components in your panel or enclosure. The orange and yellow layers add thickness compared to a standard socket. Ensure the work environment voltage does not exceed the 1000 V rating.

Dual-Layer Insulation Maintains Protection Over Time

The yellow inner layer becomes visible if the orange outer layer is cut or abraded, signalling that the socket must be removed from service. This design supports sustained safety during repeated use on energised equipment. Regular visual inspection of the insulation layers is required to maintain compliance with ASTM F1505. The tool is not rated for voltages above 1000 V.

Questions about this item

Does the T28-I insulated socket ship alone or in a set?

The listing describes a single 7/8" 12-point socket with dual-layer orange and yellow insulation; no case, rail or additional sockets are mentioned.

Why is this socket only offered in a 7/8" size?

The manufacturer lists only the 7/8" hex with a 3/8" drive, 12-point profile and 1000 V rating; other sizes would be separate part numbers.

What does the 1000 V rating mean when I use the socket on live equipment?

Each piece is individually tested to ASTM F1505 and the yellow inner layer shows through if the orange outer layer is damaged, giving a visual warning before the 1000 V protection is compromised.
