A while back I reviewed the Rockwell Jawhorse and Sheetmaster clamps stands against Ridgid’s SuperClamp. Unfortunately, Ridgid’s SuperClamp, which is almost identical to Triton’s Super Jaws XL, has been discontinued. So this review is down to the Rockwells.
Both Rockwells have a one ton clamping force and are identical in operation. Just load your work piece, engage the lock, and pump the foot peddle to clamp it down. To release, unlock and pump the foot pedal again.
Weight and Capacity
Both Rockwells can handle 600 lbs of load and have a one ton clamping force. The Sheetmaster has a larger footprint and is 10 lbs heavier than the Jawhorse.
For the extra size and weight, the Sheetmaster gives you 49” of clamping range. The Jawhorse only extends to 37 inches. Rockwell used to offer an extension for the Jawhorse but they discontinued it.
The Sheetmaster has two rollerblade wheels with more ground clearance than the Jawhorse’s rolling pin wheel. Both systems pull well, but the Sheetmaster rolls smoother.
All three stands employ a third leg/carry handle. The Jawhorse handle does not allow your knuckles to slide under for a full grip, while the Sheetmaster’s does. However, the Sheetmaster’s handle has sharp edges right over the tool’s center of gravity making it uncomfortable.
Now that I’ve checked out the Sheetmaster I don’t see it replacing two saw horses for cutting plywood. It is well suited for making end cuts, but two saw horses are good for end cuts as well as ripping length wise. Because of this, I prefer he lighter, smaller, Jawhorse. They’ve discontinued the Ridgid but the Triton looks very similar.
