ASSEMBLY
compression clamps. These clamps use a#8 x 1" machine screw, a split lockwasher and a hex nut. If
a flat blade screwdriver is used to tighten the clamps do not grasp the work immediately opposite the
blade in order to avoid injury if the blade slips.
11. Locate tubing sections tube E1 w/coupling (E1), tube (E2), tube (F), tube (G), tube (H), tube (I) and
tube (J) as well as wire clamp 15M w/insulator (M) and wire clamp 15M w/insulator (N). Please
note that as tubes are assembled the unslotted end of each tube will be pointing downward and the
slotted end will be pointing upward. Slide wire clamp 15M w/insulator (M) over tube (G) and use
the attached hardware to secure wire clamp 15M w/insulator (M) at the approximate center of the
tube. Similarly, slide wire clamp 15M w/insulator (N) over tube (H) and tighten the hardware only
enough to hold everything in place until final alignment of the 15 meter de-coupling stub.
IN THE FOLLOWING STEPS TUBES “E1" THROUGH “J” WILL BE FASTENED TOGETHER BY
MEANS OF #8 HARDWARE, BOLT, SPLIT LOCKWASHER AND HEX NUT. AN 11/32" NUT
DRIVER WILL BE USEFUL BUT NOT NECESSARY, IF A FLAT BLADE SCREWDRIVER IS
USED DO NOT HOLD THE WORK IMMEDIATELY OPPOSITE THE BLADE IN ORDER TO
AVOID INJURY IF THE BLADE SLIPS.
12. Slide one end of tube (E2) over the short smaller diameter tube emerging from the upper end of tube
E1 w/coupling (E1), try both ends for best fit, align the holes, and pass a #8 x 1¼" machine screw
through both tubes. Place a split lockwasher and a hex nut on the threaded end of the bolt and tighten
snugly.
13. Insert the unslotted end of tube (F) into the slotted end of tube (E2) and proceed as in step 12, using a
#8 x 1¼" machine screw and hardware.
Insert the unslotted end of tube (G) into the slotted end of tube (F) and proceed as in step 12.
14. Insert the unslotted end of tube (H) into the slotted end of tube (G) and proceed as before, using a #8
x 1" machine screw and hardware.
15. Proceed in the same way with the remaining tubes, using the remaining #8 hardware as needed. Note
that a small adjustable hose clamp is provided for the slotted upper end of tube (I) to permit
adjustment of tube (J).
16. Locate wire clamp 15M w/wire (L) and the attached length of stranded wire. Position the clamp
around tube (I) so that its upper edge is approximately 8.5" (21.5cm) below the upper end of tube (I).
Pass a #8 x 3/4" machine screw through the clamp holes and secure firmly with a split lockwasher
and a hex nut.
17. Locate wire clamp 15M w/insulator (K) and position it around tube (E2), using a #8 x 1" machine
screw, split lockwasher and a hex nut. The plastic insulator at the end of wire clamp 15M
w/insulator (K) should point upward.
18. Measure from the rivet of wire clamp 15M w/wire (L) to a point that is 11' 3" (3.43m) along the
stranded wire. Mark this point for future reference.
19. Pass the free end of the stranded wire from wire clamp 15M w/wire (L)
downward through the small holes in wire clamp 15M w/insulator (M) and (N)
as shown in the illustration to the right. wire clamp 15M w/insulator (M) and
(N) may be turned on their tubes so that they line up with wire clamp 15M
w/wire (L). Loop the end of the wire through the hole in the plastic insulator of
wire clamp 15M w/insulator (K) and slide it along tube (F) until the mark on the
wire appears at the small hole in the insulator. Wind the wire back on itself
above the insulator to keep the excess out of the way. Do not cut off the excess
wire.
