Guying shorter masts
depends on your application, and the
item(s) being
supported. An adequately spaced, at least 2-
point clamp arrangement on the bottom section may be
sufficient for many light duty or partially-extended
applications. When clamping to fiberglass tubes with U-bolts,
be careful not to over-tighten to avoid crushing the tube.
When in doubt, guy! Err on the side of over-engineering,
never under! Even with guyed structures, always secure the
base in a secure fashion where it cannot move.
In semi-permanent installations, be sure the bottom tube end is not plugged so that water can drain out. Water
can freeze and split the tube if allowed to accumulate. Guy anchor points should be strong enough to
withstand a great deal of pulling force, and away from the mast far enough that the guy ropes form a 45-
degree or greater angle with respect to the mast. If the guy anchor points are too close to the mast, the guys
not only exert a great deal of downward pressure on the mast, adding to the vertical load, but they have far
less mechanical advantage on the structure while doing their job of keeping your mast stable during severe
environmental conditions. Final adjustment of your guy ropes should be without excess slack, but
not so tight
as to “load” the
mast.
Leverage experienced with tall structures will make them impossible to hold at an angle, so again, keep the
structure vertical at all times during extension and retraction. Having people on all guy ropes to maintain
control
(keeping the structure VERTICAL at all times)
during raising or lowering the structure is a
must
.
When letting the structure down, be certain to maintain a firm grip on the inner tubes when you SLOWLY
release tension on the thumb clamp. Do not rely on the clamp tension only to let down each section. Gloves
(selected for a good grip on the tube surface) will be a BIG help. Always raise and lower in adequate lighting to
avoid accidentally extending the mast past the “stop” line you marked on the tubes. A
gain, ALWAYS have
adequate help on hand to maintain control of the structure when raising or lowering.
MOUNTING
Our Mast line needed a full array of mounting products that could easily be adapted for any use or situation. For permanent
or mobile / temporary use. Not to mention, built to stand the test of time. A trailer hitch mount, ground mount, and drive on
mount, using most of the same components. The same support tube can be paired with one of the plates to make a ground
mount or a drive-on mount, use the holes in the center or the holes toward the end of the plate. Pair the support tube with a
hitch bar and two of our super tough stainless square U-Bolts to make a hitch mount. With a tilt mechanism, you can have
your mast secured in the mounting base and, while the mast is down in the collapsed position, tilt it over and prop your
mast up on something to allow for easy access to the top section of your mast to operate on your antenna, flag, light
fixture, whatever you might have on top. The tilt mechanism is operated by a T-Bolt on the side of the device. You would
remove it to tilt it over. All of our mounting products are made using steel that is laser cut for precise fits and reduced
manufacturing burrs that can scratch the fiberglass masts. The mounts are powder coated for durability and to ensure your
mount has a nice smooth finish. All of the hardware is stainless to make sure that the mount will be as easily operated as
possible for as many years as possible.
