A truly FLEXIBLE nailer, the FLEX is built to install 3/8” to 3/4”
Tongue & Groove flooring without the use of pads or shims.
For the Model 50P 18-Gauge Nailer

POWERNAIL FLEX

Powernailers® are constructed in the USA and are made
of the best materials available.
Adding to the flexibility of the Powernail
FLEX, the new Power Roller speeds up the
installation and requires less effort on the
part of the installer.
The FLEX uses an adjustable foot and you
can fine-tune the nailer height according to
different wood profiles. No need for extra
shims and pads!
The Flex with Power Roller is recommended
for use on 3/8", 1/2" and 5/8" Tongue and
OPERATION
Read these instructions carefully before you use the Nailer.
Groove flooring as well as some 3/4" exotics, bamboo,
and other solid wood flooring.
The Powernail Flex uses an 18 gage Powercleat
that is less likely to split the tongue on denser, more
brittle woods and provides an excellent bond to the
underlayment. The Powernail FLEX is designed to use
cleat lengths of 1", 1-1/4", 1-1/2", and 1-3/4".
To use the Powernail Flex with Power Roller,
adjust the nailer FLEX foot to a sample of your
flooring.
Then, simply place the nailer on the floor, pull
nailer back so locating ears catch the edge
of the floor above the tongue, pull the safety
trigger and tap the plunger with the rubber
capped mallet end to let the Nailer drive and
set the nail at the correct 45 degree angle.
Nailing with the Power Roller is faster and easier. The
nailer is designed to nail from left-to-right and aides
the installer by guiding the nailer into the flooring as
the nailer is rolling along.
Consult the flooring manufacturers recommended
nailing schedule and ensure you are nailing over a
proper subfloor.
See page 3 for instructions on correct FLEX foot
adjustment.

FLEX Foot Adjustment:
Wood varies from one manufacturer to the
next. The different wood profiles may be due
to height and length of the flooring tongue and
whether or not there is a nail pocket.
First, loosen the two hex bolts under the FLEX
foot with the Allen Wrench supplied with the
nailer. (Figure 1.)
Next, set the nailer on a sample of your flooring
(see Figure 2).
Use the adjustment lever at the back of the
nailer foot to raise or lower the nailer to the
wood.
Match the Adapter Foot triangles so that it is
pointing into the 90° angle created
by the tongue and the top of the wood (see
Figure 3).
For wood with a nail pocket, line up the triangles
so at the top of the nail pocket.
When the adjustment lever is in the correct
position for your wood sample, tighten the two
hex bolts to lock the FLEX foot into place.
Always check your adjustment with a sample to
ensure the nail is driving into the nail pocket
