Appearance is a great asset day or night,
especially with material as bright and color fast as ours.
Vinyls of every quality are being made
today. The characteristics described above relate primarily to the
vinyl-polyester laminate designed by us and engineered especially
to our specifications.

Superior materials are used throughout
A
unique vinyl laminate* made to our specifications (18 oz.)
and the highest quality (14 & 16 oz.) makes our tent a lot
better.
The fabric (scrim) in the
18 oz. laminate that provides much
of the extraordinary strength of our tent, is a 1300 x 1800 denier
polyester (Dacron). The 14, & 16 oz. laminate, is a 1000
x 1000 denier polyester (Dacron). All have 18 rip-stop cords
every inch, 9 each way.

The vinyl has good color-fast
pigmentation. All our colors should last for years without fading.
The vinyl contains extra U. V. protection, including
plenty of titanium dioxide, which enables this unique vinyl to
exceed all others in sun resistance and length of life.
The extra thick 18oz. contains
even more, which enables this unique vinyl to exceed all others
in sun resistance, abrasion resistance, smoothness and length
of life.

An abundance of polyester, U. S. manufactured, is used in our
seat belts on every seam, and in our thick (#207) thread-as well
as in the inner "scrim" of our vinyl. Even our ropes
are wound with polyester for guaranteed sun resistance and abundant
strength.
Polyester is about twice
as strong as cotton, and being an oil based product, like vinyl,
it is all but impervious to mildew or rot of any kind.
Polyester does not react very much
to extremes of temperature or humidity. Its size, shape and strength
are stable, unlike cotton, hemp, or even nylon.
All the steel-to-steel connections,
are hot-dip galvanized, like coated nails, for 30 year rust resistance!
SUMMARY:
The tent top and side-wall are composed
of nothing but the finest vinyl, domestic polyester, and galvanized
steel hardware. What this means is that your tent is not only as
strong as modern science and modern technology can make it, but
it will not grow slack when cooling, soaking rains come, and then
sag into "water bags" and come down. By the same token,
it will not stretch too tightly (like nylon will) in the sun. It
will not change noticeably from one month to the next.
Superior design and
detail work may be found throughout.
The
unique bail-ring (pronounced "bell-ring") (38' and wider
18 oz., 50' and wider on all others) is suited to either "push-pole" or pulley raisings with never a chance that the center pole could
damage the tent through abrasion.

Unique
hook and ring connectors (at tent top, eave, and in 60' and wider
tents, at the quarter-band) help the tent easily endure the enormous
forces in storms that can destroy weaker tents.

Our
triple stitch seams with #207 polyester thread are about four
times stronger than a normal double stitch with #138 thread. And
again, polyester is about twice as strong as cotton. This is the
miracle of modern materials. This translates into a product you
can depend upon.

The
quarter-pole positions: In 60' and wider tents, the quarter poles
carry most of the wind load as well as the weight of the tent
itself. We therefore make these points particulary tough. The
quarter poles are naturally positioned where seams cross with
their 5700 pounds-strong seat belts.
To that we add:
An extra seat belt for 4
feet on both seams where they cross. A small and then a larger
piece of kite-shaped vinyl over the area. Three layers of our
powerful vinyl laminate, adding over 300 lbs. per inch, each. Quarter
pole domes on 60' and wider tents have tough, aluminum "heads"
of 28 square inches (a 6" disk) built right into the tent
at every quarter pole position. They articulate, staying flush with
the tent at all times.
These areas therefore become very reliable "strong
points" that can easily carry the weight of virtually any
storm. One tent-100'x148'-took 14" of wet snow in Philadelphia.
That surprised even us. With slanted quarter poles, the wind pressure
simply passes through the quarter poles harmlessly to the ground.
With vertical quarter poles that some medium sized tents may use,
about one-half of the load passes into the ground, the rest down
to the stakes.

Double
belting: To add strength and safety to every area susceptible
to stress, we use two seat belts in the following areas:
All
edges including the entire perimeter. Quarter-pole positions
as indicated above.
The seam at each "end"
of every tent. This means that if you elect to add one or more "middles" to lengthen your tent you can pull the tent
from each end very hard without special guy lines. (The strength
of this one seam is over 13,000 lbs!)
The center-band of every middle (from center
pole to centerpole) is a special belt. We use 2" wide on our smaller tents. On
our medium to large tents we use a 3" wide with 18,000 lbs.
in breaking strength.
The
10" rain-flap over the laced edges of the tent section is
closed 100% effectively with industrial vel-cro, and it looks
great. The valance of each section also connects firmly to other
sections with vel-cro. And even in winds of 100 mph, tests show
they always stay right in place. Movement simply causes vel-cro
to tighten up.
Our deluxe side-wall (curtain) is
special in four ways:
1 1⁄2" belt around edge.
Stainless
steel snap hooks and zinc grommets that will never rust.

Bi-fold
corners, 4 layers thick, so any one edge of the
sidewall can absorb
up to 1000 lbs. of stress if need be.
The vinyl
scrim of the sidewall is as strong as any tent
top material we've
seen except our own. A score of significant detail items that
cannot be enumerated here, but can be seen, used and appreciated.
Continuous research and development, evaluation and testing,
insures that Miami Missionary Tent Company will continue to advance
the state of the art.
* Two layers of vinyl bonded
permanently to either side of a polyster fabric.
