The duct fabrication procedures outlined in
this manual pertain to two common methods
of one-piece duct construction in standard
1” OR 1-1/2” ductboard. For applications
requiring ductwork larger than that which
can be constructed from a single piece of
ductboard, consult the NAIMA fibrous Glass
Duct Construction Standards Manual or your
ductboard manufactures fabrication manual
for information on the two-piece “U”, two
piece “L”, and four-piece construction method.

INTRODUCTION
Tool Features:
• FasGroov Tool identification incorporates
both the numbering system of fabrication
machines and the traditional hand tool
color coding system. FasGroov Tools are
available for both shiplap and vee-groove
fabrication methods.
• Easy, turn-the-knob, blade height adjust-
ment. Scrap lifts cleanly out of groove.
Blades are also easily removed without
removing screws.
• Molded plastic handles are ergonomically
designed to fit angle of grip and reduce
arm and hand fatigue on-the-job.
• Extruded, anodized, aluminum body is
durable and lightweight. Grooved surface
on sled bottom facilitates easy sliding.

to be scrapped.
FGV6
• 1” FasGroov kits also include a #6 tool (Tan
color coded FGV6) for creating duct sections
less than standard 4 foot lengths. The #6
replaces a shiplap knife for making a shiplap
groove at fitting end prior to closure of duct
section. The #6 may also be used for twopiece and four-piece ductboard fabrication.
Easy one-piece layout:
• FasGroov Square permits fast and accurate layout without marking cuts or calculating add-on dimensions. Lay out duct-
board as you cut. Simply align dimension on
FasGroov Square with edge of previous cut
and move across the board. Square is also
easily adjustable for angled cuts.

use this point to
cut fiberglass without
tearing ductboard skin.

to raise or

and adjust
depth of cut.

Single blade knives:
• Single blade FasGroov Knives are safer to
use and also feature comfortable molded
handles. Male and Female Shiplap Knives
can be used on closed duct sections.

For right or left hand use:
SETTING UP TOOL
• Right hand orientation of 1” kits is easily changed by converting #5 Tool and
FasGroov Square for left hand fabrication.
Tool handles may also be turned around to
provide left hand grip angle.
Right hand
operation.
Left hand
operation.
CONVERTING FASGROOV SQUARE
FOR LEFT HAND USE.
1. Remove the angle adjustment knob and the end
pivot knob.
2. Position the ruler stamped leg so that the 3 holes
are to your left. (Rule reads left to right.)
3. Remove the protractor for the “L” shaped leg by
removing the two screws.
4. Flit the protractor over and install on the opposite
end of the “L” shaped leg.
5. Place the “L” leg/protractor assembly on top of
the ruled leg.
6. Align the pivot knob holes and install the pivot
knob.
7. Install the angle adjustment knob in any of the
fixed positions or the sliding position.
8. After converting your square for left hand use,
double check the accuracy in the fixed° position
with a roofing square. Built-in manufacturing
hole tolerances will allow you to true the square.
Note: 1-1/2” Kit cannot be converted for left hand use.
Adjusting Fasgroov Square
PREDETERMINED SETTINGS
Place adjustment knob into hole corresponding
to most used angles.
OTHER ANGLES
Place adjustment screw into protractor adjustment slot and tighten at desired angle.

Step 1: Remove angle adjustment knob and
fold ends of FasGroov Square together.
Step 2: Place angle adjustment knob into the

1/2”
Push the FasGroov #1 Tool along the left edge
of a test piece of ductboard. Measure the depth
of cut of the female shiplap groove, it should be
half the thickness of the ductboard (see illustration).
If adjustment is needed: (1) Turn the blade
adjustment knob counterclockwise to lower the
blade for a deeper cut or (2) Turn the blade
adjustment knob clockwise to raise the blade
for a shallower cut. Repeat adjustment until the
proper depth of cut is achieved.

the amount of fiberglass remaining between the
foil backing and the deepest part of the shiplap
cut (see illustration).
If adjustment is needed: (1) Turn the blade
adjustment knob counterclockwise to lower the
blade for a deeper cut or (2) Turn the blade
adjustment knob clockwise to raise the blade for

Measure the amount of fiberglass remaining
between the foil backing and the deepest part
of the vee-groove cut. There should be 1/8” of
fiberglass remaining (see illustration for width
of cut.)
If adjustment is needed: (1) Turn the blade
adjustment knob counterclockwise to lower the
blade for a deeper cut or (2) Turn the blade
adjustment knob clockwise to raise the blade for

FASGROOV #5 TOOL
Push the FasGroov #Tool through a test piece of

The blade should cut deep enough to skin all of
the fiberglass off the foil backing. By using more
pressure on the FasGroov #5 Tool, any remaining fiberglass may be cleaned off the foil.
If adjustment is needed: (1) Turn the blade
adjustment knob counterclockwise to lower the
blade for a deeper cut or (2) Turn the blade
adjustment knob clockwise to raise the blade for
a shallower cut.
Repeat adjustment until the proper depth of cut
is achieved.
Note: It is important to use this tool according to
the direction arrows on the label.
