Summary
Meet Gruv-One RG-4M, the ultra-compact manual roll groover built for tight spaces. With a 1 1/4"–6" grooving range, a lightweight 10 kg design, and just 90 mm of required clearance, it can go where many conventional groovers simply can’t. Designed for pipes already installed in the air, Gruv-One makes In-The-Air grooving easier, lighter, and a lot less frustrating.

Meet Gruv-One RG-4M: The Roll Groover That Goes Where Others Can't--- Small in size. Big on access. Built for In-The-Air grooving.
Sometimes, the pipe isn't the problem.
The space around it is.
Meet Gruv-One RG-4M, our ultra-compact manual roll groover designed for those awkward "How am I supposed to fit a groover in there?" moments.
With a grooving range of 1 1/4"–6", a weight of just 10 kg, and an operating clearance as small as 90 mm, Gruv-One is built to make grooving in tight spaces dramatically easier.
And when the pipe is already up in the air, that’s where Gruv-One really shines. That’s why we call it the In-The-Air Roll Groover.
Small enough to get into tight spots.
Light enough to handle without a struggle.
Capable enough to cover the pipe sizes you actually need.
So, if you've ever stood in front of a pipe that was just a little too close to the wall and thought, “Well… this is going to be fun,” — give Gruv-One a try.
It might just surprise you.
