Mast Ties
1-
Install the fi rst rigid dual clamp on the vertical tube of the mast tie frame (fi g. 6.19).
Attach the mast tie to the rigid dual clamp. Tighten the clamp to 60 lb-ft (80 N-m) of torque.
2-
Lock the installed rigid dual clamp in place by installing additional rigid dual clamps in
front and behind as shown in fi g. 6.19.
Installation of additional rigid dual clamps to secure the mast tie
36" (0,9 m) mast tie
In a setup requiring a unlinked confi guration or a wider plank confi guration (4 to 8 planks), or
using equipment or accessories such as mast tie extensions, forward bridge extensions, a
swivel bridge, a hoist, weather protection, etc., the tension/compression is highly increased.
In such situations, it is
mandatory
to attach an additional rigid dual clamp
behind
and
in
front
of the rigid dual clamp attached to the mast tie frame (see fi g. 6.18).

tie extension
1-
Insert a mast tie extension into the tube of a 36" (0,9 m) mast tie. Secure in place with
two pins (fi g. 6.17).
2-
Install all the rigid dual clamps required and adjust the mast tie. For more information,
refer to the installation instructions for standard mast ties on p. 86 and for additional
rigid dual clamps hereafter.
3-
Repeat steps 1 and 2 for the other two mast ties. Once all mast ties are installed, brace
the mast ties by installing 36" (0,9 m) mast tie extension tubes secured to the mast tie
assemblies with swivel dual clamps (fi g. 6.16).
4-
Make sure all clamps are tightened to 60 lb-ft (80 N-m) of torque.

Installation of mast ties with extensions
In a confi guration requiring the use of mast tie extensions, it is important to note that only
one
mast tie extension per mast tie is allowed
(a maximum of 60" or 1,5 m). It is
mandatory
to strengthen such tie confi gurations by installing diagonal mast tie braces secured into
place with swivel dual clamps. For any other mast tie confi guration not shown in this owner’s
manual, contact a qualifi ed person or the distributor/service center. For the defi nition of a
qualifi ed person, refer to p. 7 of the
Performance and Safety Rules
section.
WARNING
It is important to verify each mast tie of an installation that has been exposed to
winds exceeding 102 mph (164 km/h).
