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 meth-
od.

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 shorten

by measuring

edge of material
to be scrapped.
Use knob
under handle
to raise or
lower blade
and adjust
depth of cut.
• 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 two-
piece and four-piece ductboard fabrication.

Easy one-piece layout:
• FasGroov Square permits fast and accu-
rate layout without marking cuts or cal-
culating 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.
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.
FGK

cut fiberglass without

For right or left hand use:
• Right hand orientation of 1” kits is eas-
ily 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.

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.

Hand Tool blade height
adjustment:
FASGROOV #1 TOOL
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 illustra-
tion).
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.
FASGROOV #2/4 AND #3 TOOLS
Push the FasGroov #2/4 Tool and FasGroov #3
Tool through a test piece of ductboard. Measure
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
a shallower cut.
Repeat adjustment until the proper depth of cut
is achieved.

VEE TOOL
FASGROOV-VEE TOOL
Push the FasGroov-Vee Tool through a test
piece of ductboard.
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
a shallower cut.
Repeat adjustment until the proper depth of cut
is achieved.
FASGROOV #5 TOOL
Push the FasGroov #Tool through a test piece of
ductboard.
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 remain-
ing 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.

Blade removal, replacement:
Since the blade adjustment mechanism is the
same for all FasGroov Tools, this procedure
applies to any tool requiring blade removal/
replacement.
BLACK PLASTIC SUPPORT BLADE ASSEMBLY

Loosen Screws
Slide and remove worn blade assembly.
Place new blade into the black plastic support
and retighten screws.
Note: Initial cutting friction may be realized due
to rust prevention factory finish on the blade.
