Will it work with my tools?

Yes. It has a 3/8" drive, and the 4 adapters in the box let you use it with 1/4", 3/8" and 1/2" sockets, with your hand ratchet or with an impact driver

Can it break loose a seized bolt?

It's built for reach, not brute force, and rated up to 53 ft·lb (72 Nm). Crack a stubborn bolt loose with a breaker bar first, then let the Offset Extension spin it out in seconds where nothing else fits. That's also how the chain stays in good shape

Will it arrive before the holidays?

Every order ships within 10–15 days with tracking. If it's a gift, order before December 8 so it's under the tree in time

The problem

You can see the bolt. You just can't reach it.

It's always the one behind a hose, a bracket or the back of the engine. Your ratchet won't fit, a longer extension hits something on the way in, and the only way left seems to be pulling half the car apart to get one bolt out.

That's how a ten-minute job turns into a whole Saturday, a pile of parts on the floor and a couple of skinned knuckles. Or into a repair bill, because the shop charges you for every hour it takes them to get there too.

How it works

Turn the bolt from where there's room to swing.

The Offset Extension slides its thin end over the bolt you can't get to, while the other end sits out in the open where your ratchet or impact driver fits. A steel roller chain inside the bar carries every turn from one end to the other, so the bolt spins as if you were right on top of it.

01

Slide it in

The slim bar fits into the gaps where your hand and your ratchet can't go

02

Turn the open end

Use your ratchet, a drill or an impact driver out where you have space to work

03

The chain does the rest

The turn travels through the bar and the buried bolt comes right out

Where you'll use it

Not every day. But when you need it, nothing else will do.

It lives in the toolbox until the day a bolt is buried where no other tool can follow, and from then on you'll reach for it first. Cars and trucks, motorcycles and ATVs, decks and fences, the workshop bench.

Northmark Offset Extension with its 4 adapters
In the box

One bar that fits the sockets you already own.

There's nothing new to learn and nothing else to buy. The bar takes a standard 3/8" drive, and the four adapters in the box let it work with your 1/4", 3/8" and 1/2" sockets and with screw bits, so it joins the tools you already trust.

Built for reach, not brute force

We'd rather tell you now than have you find out under the hood. The Offset Extension is made to get to bolts nothing else can reach and spin them out fast, not to replace your breaker bar. It's rated up to 53 ft·lb, so if a bolt is rusted solid, crack it loose with a breaker bar first and then finish the job with the Offset Extension. Used that way, the chain inside stays in good shape job after job.

The holiday gift

For the one who fixes everything.

Every family has one: the person who changes the oil, fixes the fence and gets called whenever something breaks. They already own every regular tool, which is exactly why this one stands out. It's the tool they didn't know existed, and the one they'll show off to their friends.

Choose the 2-pack and we add a free HALO™ headlamp, so they finally have light right where their hands are working, or keep one Offset Extension for yourself.

Questions

Before you order.

What size is it?

The bar measures 15.2" long, 1.5" wide and only 0.7" thick, with a 3/8" drive. The four adapters in the box let it work with 1/4", 3/8" and 1/2" sockets and with screw bits.

Can I use it with an impact driver?

Yes, it works with a hand ratchet, a drill or an impact driver, up to a maximum torque of 53 ft·lb (72 Nm). For the heaviest jobs we recommend loosening the bolt by hand first, which keeps the chain in top shape for longer.

Does it work in both directions?

Yes, it has a zero-degree swing arc and turns a full 360° both ways, so you can take a bolt out and put it back in with the same tool.

When will it arrive?

Every order ships within 10–15 days with tracking. If it's a holiday gift, order before December 8 so it arrives in time.

What if it's not for me?

You have 60 days from delivery to send it back. Just write to us and we'll walk you through the return.
