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 methods.

INTRODUCTION
Shiplap Method
Vee-Groove Method
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 adjustment.
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.

CUT FLAP
CUT FLAP
Use #6 Tool
to shorten
length of
duct section,
by measuring
from outside
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 accurate
layout without marking cuts or calculating
add-on dimensions. Lay out ductboard as you
cut. Simply align dimension on FasGroov Square
with right 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.

For right or left hand use:
• 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.

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. Flip 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 90° position with a roofing square.
Built-in manufacturing hole tolerances will allow you
to true the square.
Note: 1-1/2” Kits 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 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.
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.
