Trailer Hitch Vise · THV618

Every 2" Receiver Is Now a Workbench.

Slide it into the hitch, drop the pin, and go to work. 7,700 lbs of clamping force, a cast-in anvil, and pipe jaws in 60,000 PSI ductile iron, on the truck, the trailer, or bolted to the table.

THV618 Product Overview

Every 2" receiver is now a workbench. The THV618 slides into any standard 2" hitch receiver and pins in place with the included hitch pin. Truck, trailer, tractor, or shop table: wherever you can park a receiver, you have a solid vise at working height. Pull the pin and it's off in seconds.

Cast from 60,000 PSI ductile iron with 7,700 lbs of clamping force, it holds through hammering, prying, and heavy wrench work instead of flexing under it. Jaws open to 5.7" (146mm), and sitting out past the bumper gives you clear access for cutting, grinding, and welding. A 5.9" x 2.4" anvil is cast into the top, so you can straighten, flatten, and peen without beating on your tailgate.

Below the flat jaws, serrated pipe jaws hold round stock and tube. Four 5/16" (8mm) locating pins drop into the jaw tops as stops and fences. And when the truck is parked, the base flange bolts straight down to a BuildPro table.

Serrated pipe jaws below the flat jaw faces of the THV618
Pipe jaws
Round stock, no roll

Serrated V-grooves sit below the flat jaw faces and bite into pipe, tubing and round bar, so it stays put while you cut, thread or weld.

Repeatable setups

Four 5/16" (8mm) pin holes in each jaw, four pins in the box. Set them as stops or fences for repeat positioning, or use them to hold odd shapes the flat jaws can't.

Hammer on it

A 5.9" x 2.4" anvil is part of the same 60,000 PSI ductile iron casting. Straighten, flatten and peen right on the vise instead of beating on your tailgate.

Jaw capacity
5.7" opening, 5.9" wide

Jaws open to 5.7" (146mm) across a full 5.9" (150mm) face. Enough mouth for thick stock, and enough face to hold it flat while you work on it.

Ductile iron
Built to take a beating

Cast from 60,000 PSI ductile iron with 7,700 lbs of clamping force. Shock resistant instead of brittle like gray cast, so it holds through hammering, prying and heavy wrench work.

Pin and go
Fits any 2" receiver

Slides into a standard 2" (51mm) receiver and locks with the included 5/8" hitch pin. Truck, trailer, tractor or the receiver on your shop table: park it and you have a vise at working height.

Quick release
Off in seconds

Pull the clip, pull the pin, slide it out. No bolts, no bench, nothing left on the truck when the job is done.

Bolts flat to the table

The base flange takes 5/8" or 16mm bolts on 2" or 50mm spacing. Drops straight onto BuildPro and other modular welding tables when you want it as a bench vise.

FAQ

Straight answers on fit, mounting and what the THV618 will and won't do. Scroll the list for more.

Will it fit a 1-1/4" receiver?

No. The THV618 is sized for a standard 2" (51mm) square receiver only.

Does it come with a hitch pin?

Yes. A 5/8" hitch pin and R-clip are in the box, so it mounts straight out of the packaging.

Can I use it without a truck?

Yes. The base flange bolts flat to BuildPro tables and any table with 5/8" holes on 2" centers or 16mm holes on 50mm centers.

Can I clamp pipe in it?

Yes. Serrated pipe jaws sit below the flat jaw faces and grip round stock, tubing and pipe so it can't roll.

What are the pins for?

Each jaw has four 5/16" (8mm) holes and four pins are included. Drop them in as stops or fences for repeat positioning, or use them to hold odd shapes the flat jaws can't.

Can I hammer on it?

Yes. A 5.9" x 2.4" anvil is cast into the top of the fixed jaw, in the same 60,000 PSI ductile iron as the body. Straighten, flatten and peen on the vise, not your tailgate.

How wide does it open?

Jaws open to 5.7" (146mm) across a full 5.9" (150mm) face.

How do I take it off?

Pull the R-clip, pull the hitch pin, slide it out. No tools, nothing left on the truck.

What is it made of?

60,000 PSI ductile iron with a hammertone silver finish. Ductile iron is shock resistant, not brittle like gray cast iron, so it takes hammering and prying without cracking.
