Meet the Updated H402 Pipe Chain Vise

Stronger. Smoother. And Slightly Overqualified for the Job.

Let's be honest — pipe work is hard enough already.
Your tools shouldn't be the reason your day gets worse.

That's exactly why we upgraded our classic chain vise and introduced the unpdated H402.
Compared with the old version, the undated H402 didn't just "hit the gym" — it moved in and never left.

With a heavier-duty material design and a RCS casting process, the body is denser, tougher, and noticeably smoother. The surface is clean, the casting is solid, and everything feels like it's built to last.

No sharp edges. No sketchy castings.
Just honest metal that's here to work.

We also listened carefully to real-world feedback — especially from that base that cracked after getting caught by the chain in freezing, miserable jobsite conditions.

So yes, we added a dedicated chain wear plate on the back side.

Why?
Because this way, the tool's life gets a little longer — and let's face it, no one's money grows on trees.
This simple upgrade keeps the chain firmly in place, improves clamping stability, and makes operation safer and more predictable.
It also helps hardworking crews out in the cold save a bit more cash—maybe enough for a few beers to warm up after the job is done.
As for versatility, the updated H402 covers a wide working range from 1/8" to 6", and securely clamps:

●Galvanized steel pipe
●Stainless steel pipe
●Copper pipe
●Aluminum pipe

If it's round and needs holding, the H402 is ready.

In short, the updated H402 Pipe Chain Vise is built for professionals who want less drama, more grip, and tools that quietly do their job without complaining.

Strong where it matters.
Smooth where it counts.
And yes—it looks good doing it.

Let's enjoy the product video for you guys below, hope you will like it!
