Flat wrench 21 mm 1000V, NEO tools model 01-124 — insulated single-sided hand tool

NEO tools flat wrench 21 mm 1000V (single-sided) is an open-end insulated hand tool designed for work on electrical installations up to 1000 volts. The tool combines a conventional 21 mm open jaw with a fully insulated handle that meets insulation requirements for live electrical work. It is intended for tightening and loosening nuts and bolts in environments where electrical safety and operator protection are required.

Advantages

The insulated handle provides protection against electric shock up to the specified voltage rating while maintaining a compact and lightweight profile for handheld operation. The open-end jaw offers firm contact with fasteners and allows access in confined spaces where socket tools cannot be used. Built to typical NEO tools quality standards, the wrench balances durability and ergonomics for repeated use in maintenance and installation tasks.

Suitable for

How to use

Before use, visually inspect the insulation for cracks, cuts or other damage and verify the tool is clean and dry.
