OPTION 2: POCKET HOLE JOINERY &
NAIL FIN TRIM
Follow these steps to assemble the Nail
Fin Trim by screwing the trim together
using a pocket hole joinery and then
installing the trim on the wall as a
unitized frame.
The advantage with this option is that
the trim joints will be tighter, and should
not require shimming to keep them ush.
Joints may be assembled with either 45°
miters or butt & pass methods.
POCKET HOLE REQUIRED EQUIPMENT:
Pocket hole jig w/drill bit
2" Pocket screws (exterior grade)
Portable pocket hole jigs are readily
available from retail suppliers.
INSTALL:
Measure and cut the trim pieces to
the proper length as normal, then
touch up paint all cut ends. Be sure to
add the proper gap amount to your
measurements.
(Fig. A)
Please follow the tool manufactures
instructions by setting up the jig and
drill. From our experience best results
are obtained by setting the jig for 1"
material and the drill depth gauge for
¾" material using 2" screws. Because
manufactures dier, nd the settings
that work best for you. Experiment on a
test piece rst.
Follow the hole placement diagrams
below for your situation. Drill 2 holes for
4" trim and 3 holes for 6" trim. Place the
holes from the edge of the material at
the dimensions shown for each joint to
join the material together.
Proper hole placement is important for
screw holding power. Caution: drilling too
close to the edge may cause material to
split.
Using a scrap piece of the nail n,
approximately 2" x 3.5" (circled), will help
keep the trim clamped securely in the jig
while drilling.
(See Fig. B, C, & D)
After all four joints are drilled begin
assembling the frame.
(Fig. E)
Follow recommendations
from the manufacturer on
installing screws with the
trim face down. Take care
to protect the pre-nished
surface from damage during
assembly.
With the pieces of trim
assembled, take the unitized frame
to the desired area on the wall, t the
trim frame to the opening leaving the
required gap between trim and opening.
(Fig. A) Level the trim frame and fasten
through the nailing n lling every 3rd
hole. Nail heads should set rmly to
the face of the n, but be careful to not
overdrive to distort or damage the n
surface.
Make sure that you do not overdrive
nails. Fasten EVERY 3RD HOLE. We
recommend using 1-3/4" StormGuard
®
Ring shank nails from Maze Nails.

INSTALLATION
Trim ends may lightly touch adjacent trim edges around windows and doors only. Re-prime and paint all cut ends.
When installing trim around windows and over window anges, be sure to follow the window manufacturers installation
instructions.
All openings must be properly sealed and ashed in a manner that prevents moisture intrusion or buildup. Flashing may be
sealed to the water-resistive barrier by using adhesive ashing or housewrap tape. (See ALL diagrams)
When trim is installed adjoining vinyl siding, install Z-ashing with a 4 inch upper leg between horizontal trim and J-channel.
(See diagram 8a)
Horizontal trim or bands shall be ashed with a sloped metal Z-ashing to redirect water away from the wall assembly.
