Conduit Measuring Tape
JetLine
® TT31 True Tape™ and ST40 Super True Tape™
provide an accurate means of measuring the length of
conduit runs already in place. Both are marked in
1' increments.
When measuring for wire length, measure from terminal to
terminal, not from end of conduit. See Conduit Measuring
Tape Table for allowances to be made for 90° bends, 45°
offsets, and panel boxes.
7.7 Seal-Offs
The GB/JetLine ® seal-offs are the final connection between
the blower or Blo-Vac ™ hose and the conduit. Seal-offs
attach to the JV07 or B26 Dial-A-Line™ body. The tapered
seal-off cone (five sizes to fit
1 ⁄
2
" through 6" conduit) must be
held firmly in the conduit when blowing or vacuuming line
in conduit.
JV07 Dial-A-Line™ Body
The small JV07 Dial-A-Line™ body is used in conjunction
with the BV12 Hose Adapter, accepts the JV08 Short Seal-
Off, JV09 Long Seal-Off or the JV12 Seal-Off. The perforated
dial plate on the JV07 is adjusted to feed pull line up to
1 ⁄
8
"
diameter or for feeding TT31 True Tape™. Close off the feed
port when Power Saver™ or Tag-Along™ line packages are
used or when vacuuming.
JV08 Short Seal-Off
The JV08 Seal-Off is used in close quarters such as 2' x 4'
electrical boxes, etc. It may be used on
1 ⁄
2
" through
1 1 ⁄
4
" conduit.
JV09 Long Seal-Off
The JV09 Seal-Off is similar to the JV08, except for length,
and is used to reach conduit in deep electrical boxes.
JV12 Seal-Off
The JV12 Seal-Off fits conduit sizes 1
1 ⁄
4
" through 2 1 ⁄
2
".
B26 Dial-A-Line™ Body
The B26 is a large seal-off body that can be coupled directly
to either the 1
1 ⁄
2
" or 2 1 ⁄
2
" hose assembly. It is used with the
BV23 and BV24 seal-offs. The dial plate has a small hole for
feeding pull line up to
1 ⁄
8
" diameter. The large hole is for larger
pull line and rope up to 1 ⁄
2
" diameter. The slot is for feeding
TT31 True Tape™ or the feed port may be closed off when
using a Tag-Along™ line package with line carrier or
when vacuuming.
