NOTES:
Our boom pieces are all drilled on a very precise drill press. This insures that all the bolts are
snug when assembled. Your new DB 36 Boom is the first of this new interchangeable boom
design. If your boom ever gets damaged or destroyed we can now just send you whatever
boom section is damaged.
Always apply lubricant to stainless steel bolts that are using stainless steel nuts.
This
will prevent the two from galling together. Each bolt has a specific length for the tubing it is
holding together this is critical so that only the shank is engaged in the tubing. Use 5 washers
per bolt to secure the bolt.
Figure 2
Apply a thin film of connector protector or a spray-on lubricant (i.e. WD-40, Dry Lube) to the
male engagement area of the boom sections.
The boom ends will have a color coding so that you know which pieces slide into each other.
Match the colors as shown in
Figure 1
below and slide the boom pieces together until the
pre-drilled holes align.
Secure the correct 1/4” bolts and washers onto the boom as shown in
Figure 2
Repeat this for each section until the boom is completely assembled.
The final step is to secure the eyebolt as shown in
Figure 1
and
