The PortaMate PM7050 MEGAVISE is a portable clamping station that looks like it may be a contender to the Rockwell Jawhorse. With a clamping force of 1500lbs, a 34.5″ capacity, and three sets of interchangeable clutch plates, the MegaVise looks to be higly capable.
The MegaVise’s jaws are set to the approximate workpiece size by sliding the fixed jaw along its rail and then securing it with a snap-pin stop. The snap-pin design looks to be quite sturdy, and should not wear down with use. Final clamping is done by closing the screw vise in a typical manner.

Included with the MegaVise are 2 log jaw clutch plates, 2 pipe grooved clutch plates, and 2 single groove clutch plates. The MegaVise collapses into a (relatively) compact and storable size.
PortaMate’s MegaVise is priced at about $170.

This is awesome. Haven’t seen this before. It’s nice at least having another option to consider, although it will be hard weighing the pros/cons of each one.
Looks like the Jawhorse foot-operated clamp is faster, and is more portable. I don’t see wheels on the portamate.
Also, the Jawhorse has a huge plywood attachment. Although it’s $50 extra, at least it’s available to you if you ever need it.
Do you know if the Jawhorse jaws can be reversed so that when you press the pedal the jaws open? I seem to recall seeing that in one of their demo videos, but can’t find it on their site.

Don’t worry, there are enough differences between the two that a MegaVise vs. Jawhorse comparison is in the works.
The Jawhorse jaws can be reversed, but that is done to provide the stand with a greater holding capacity.
Neither tool can be used as a spreader.

Stuart, does the plywood attachment for the Rockwell fit on the Megavise?
Stuart says
Absolutely not. The Rockwell plywood attachment can only be used on the JawHorse.
