Attach the Support Bracket
This section describes the installation of the external support bracket. For external mounting, the
base plate and support bracket should be fitted loosely with all fasteners installed to ensure
everything aligns. Once alignment is achieved, all bolts can be tightened according to these
instructions.
1. Using the dimensions shown in Figure 5-8 or using the support bracket as a template, drill six
holes to mount the support bracket. The support bracket should be at least 1 inch (25 mm)
above the weep hole and at least 3 inches (76 mm) below the collar. The support bracket
should be as high as possible on the mast and not block the weep hole.
Figure 5-8 Support Bracket Mounting Dimensions
2. Remove all the support bracket bolts holding the clamp halves together.
3. Install the clamp around the mast base tube and loosely re-install the six 3/8-16 bolts/
washers/lock washers.
4. Loosely install the customer supplied 3/8 inch or M10 bolts, lock washers and flat washers.
Bolt length depends on the specific application and is to be determined by the installer. If all
the holes align, tighten the support bracket to the support structure. The recommended
installation torque for an M10 stainless steel fastener is 28-33 Nm (245-290 in.-lb.). The
recommended installation torque for a 3/8 inch stainless steel fastener is 21-27 Nm (190-240
in.-lb.). Finally, tighten the mast clamp bolts to the same torque. Be careful not to over-tighten
these clamp bolts because it may deform the base tube and hinder mast function.
