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.

Use
#6 Tool
to shorten
length of
duct section,
by measuring
from outside
edge of material
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.
FGK
Duct Knife
use this point to
cut fiberglass without
tearing ductboard skin.
Use knob
under handle
to raise or
lower blade
and adjust
depth of cut.
1/2”
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.
