11 mm insulated open-end wrench

The Gray Tools MEBO11-I is a 11 mm open-end wrench insulated for live-line work up to 1000 V. Each piece is individually tested to ASTM F1505. It suits electricians and maintenance technicians who need verified protection on energised equipment.

Verify voltage rating and jaw size

Confirm that the 1000 V rating matches the maximum system voltage you will encounter. Check that the 11 mm hex opening fits the fasteners on your panel or apparatus. Inspect the dual-layer insulation before every use; damage to the outer orange layer exposes the yellow indicator beneath.

Hand-tool thermal and power profile

As a non-powered hand tool it generates no heat, draws no current and produces no audible noise during operation. The insulated coating adds negligible mass and does not affect torque feel. Store away from sharp edges to preserve the dielectric layers.
