11/16" 1000 V Insulated Offset Wrench

This insulated deep offset wrench is built for electricians and maintenance technicians who work on live low-voltage panels up to 1000 V. The 11/16 inch opening fits standard imperial fasteners found on switchgear and terminal blocks. The blade is forged from chrome-vanadium steel, hardened for durability, and manufactured to DIN 3110 dimensions. It is supplied new and ready for immediate use on certified insulated tool kits.

Simple single-tool fitting with no assembly

The wrench requires no installation beyond selecting the correct fastener size; the deep offset profile clears obstructions so the jaw seats fully on the nut. The only common issue is attempting to use the 11/16 inch jaw on metric or worn fasteners where the fit is loose, which can round the corners. Inspect the insulation before each job; any crack or abrasion means the tool must be removed from service. No calibration or adjustment is needed.

How do I confirm the 11/16 inch insulated wrench meets the 1000V DIN 3110 rating after setup?

Verify the 1000Volt marking and DIN 3110 stamp on the chrome-vanadium steel blade, then test insulation integrity with a calibrated voltage tester before live work.

What comes in the box with the 21054 insulated deep offset wrench and what must I buy separately?
