studs, push against a board long enough to span the distance of the studs so as to
prevent breaking through the drywall.
2. Ratchet the lever handle until faceplate contacts the stationary surface
3. Continue to ratchet until the self-adjusting jaw draws the fl oor tight for nailing

of your fl ooring and use the Powerjack to push against your fl ooring strips.

The POWERJACK Model 500 is designed to push or pull fl ooring strips into place
and hold them tightly.
Easy to operate! Use the lever handle to ratchet the faceplate against a stationary
surface. Continue to ratchet until the self-adjusting jaw draws the fl ooring to the
desired position. The POWERJACK can be left in place while you nail down the
fl ooring strip. To release the POWERJACK, simply push the handle to full forward
position.
The Model 500 POWERJACK sits on top of your fl ooring and gains leverage against
a wall or a wall-stud. When a stud location cannot be determined, a board long
enough to span the distance of the studs should be used to prevent breaking through
the drywall (picture 1).
When not near a wall, the Model 500 can also be used mid-fl oor by screwing the base
plate directly to the sub fl oor and pushing against your fl ooring strips.
(see picture 2).
Under the toe kick of a cabinet, the POWERJACK Model 500 can be used to tighten
boards and hold them in place (see picture 3).
The Powerjack 500 self adjusts to the thickness of the wood fl ooring being installed.
