Insulated Extension Bar 250 mm

The Knipex 98 35 250 is a 250 mm insulated extension bar with a 3/8 in. square drive on both input and output. It is rated for 1,000 V AC work and built from alloy steel with a chrome finish. The 10 in. length helps reach fasteners in deep or confined locations.

Suited for live electrical maintenance

Electricians and technicians working on energised panels up to 1,000 V AC will find the insulation and reach useful. It is not for anyone needing a different drive size, a shorter or longer reach, or a non-insulated extension for general mechanical tasks.

3/8 in. square drive compatibility

The bar accepts only 3/8 in. drive sockets and connects only to 3/8 in. drive ratchets or torque tools. Verify that your existing socket set and drive tools match this size before purchase.

Questions about this item

What does the 1,000 V AC rating mean when I use this extension in a live panel?

It means the extension is tested and insulated for work on circuits up to 1,000 volts AC, so you can reach fasteners inside energised equipment without the metal shaft conducting.

How does the 3/8" square drive limit the sockets and ratchets I can attach?

Only 3/8" drive sockets and ratchets will fit; larger 1/2" or smaller 1/4" tools cannot be used with this extension.

Will the 250 mm length and chrome finish clear the bolt recesses on my gearbox?

The 250 mm shaft reaches deep recesses, and the chrome-plated alloy steel resists corrosion while sliding past tight clearances.
