No. 670 Hardwood Plank Jack
This jack has a threaded pushrod that produces all the power of dog-and-ratchet jacks, but without the backlash or dog breakage problems. With every turn of the ratcheting handle, this jack pushes then holds and does not give. It adjusts between the wall and the last plank quickly by pushing down on the oversized handle. Push plate is reversible for when sheetrock does not go all the way to the floor or for working very close to the wall. Fastens down for use in the middle of the room using holes in the base. Provides up to 2000 lbs. of pushing force to move planks as necessary. Net weight: 8.7 lbs.
