INTRODUCTION:
The NAVI-TRAC frame configuration is based on the hip roofed square tent shown below, right.
Hip bars connect corners to the peak, and rafters connect eave bars to the peak. The square can be
extended into a rectangle by adding 10’, 15’ or 20’ bays made up of rafters and the appropriate ridge/
eave bars (see below). In the square tent, female eave bars and rafters are connected to eave weldments by rigid slip joints. Hip bars and eave/ridge bars and rafters in the middle bays use easy to
install drop-in fittings.
The NAVI-TRAC frame is made up of extruded aluminum members joined by weldments such as corner weldments, ridge weldments, eave weldments, etc. The aluminum frame members themselves are
extruded with channels into which the NAVI-TRAC fabric “kedar” is fed.
The first bay added to the square tent shape is a “starter” bay. This starter bay allows a slip fit
connection to the square tent eaves on one end of the weldment and a drop-in connection for the new
starter bay eaves on the other end of the weldment.
Subsequent bays added to the unit are “extension”
bays. Extension bays allow drop-in connections on
both ends of the eave weldments.
The chart on page 5 lists components needed for
the 50’ x 50’ square tent, the first (starter) extension, and for each additional extension to be added
to the unit. Note: starter mids or bays and extension mids are available in options of 10’, 15’ or 20’
increments of length, as shown.

50’ NAVI-TRAC Installation Safety Guidelines
Your installation techniques will evolve to fit the needs of your clients, the experience level of your crews, the nature of other tentage on-site, and the equipment that you have most readily available. We encourage you to begin with a crew of (4) workers and
only reduce this number as your experience level allows you to do so
safely. Whatever techniques you adapt for your crews, we encourage you to keep safety utmost in mind.
Please read through this assembly manual completely before beginning your installation. Be sure the proper equipment, crew and
safety precautions are in place. We hope that you enjoy the design features of the NAVI-TRAC each time the unit is installed.
1. It is recommended that workers wear safety shoes and hard-hats on site.
2. When moving beam sections by hand, use proper lifting techniques to protect the back, and avoid pinching fingers while
making hardware connections.
3. Never permit bystanders or uninvolved to stand or walk even briefly in the falling path of a beam as it is
being raised or lowered.
4. Be aware to avoid contact of beams with any overhead power lines near the site.
5. When anchoring the structure, avoid all underground power lines and gas lines or other utility easements. Local
authorities should be able to map the location of these obstacles.
6. Keep site clear of debris to avoid tripping, especially while carrying components or bundles of fabric.
7. Do not drag bundles of fabric on concrete, asphalt, or ground as this can cause damage to the fabric from abrasion
through the bag.
8. When lifting the NAVI-TRAC frame, be sure to use the heavy duty NAVI-TRAC frame lift. The standard Anchor frame
lift was not designed for the weight of the NAVI-TRAC frame. When lifting each side of an end section, (2) NAVI-
TRAC frame lifts should be used.
9. Before pivoting beams to vertical, clear the area of items that could cause tripping or slipping.
10. Before pivoting middle beam, install the cross-cable for safety bracing. On the 50’ NAVI-TRAC, the
cross-cable should be left in place as an essential part of the structure.
11. NOTE: Hinged baseplates should be used only on middle beams supplied as “extensions” and not as a component of an
end module. End module plates should all be fixed, and end module eave connections should be rigid, slip joints. Use
of hinged baseplates in the end module could cause the end module to collapse during installation.
12. When using ladders to make peak connections, be sure the ladder is tall enough that workers can reach the peak from a
ladder step consistent with the safety recommendations for the ladder being used. On middle beams, secure the eaves
before climbing the ladder to secure the peak.
13. For any NAVI-TRAC of 100 ft or more in length, the uprights and rafters of one middle bay must be cross-cabled on both
sides in an “X” fashion for each 100 ft. of length (see illustration on page 20.)
14. For proper loading and anchoring information, consult the appropriate NAVI-TRAC blueprint available from Anchor
Industries Inc.
15. Before installing fabric, verify that all hip, brace, and rafter pins are seated into weldment fittings and
secured by lanyard pins.
16. The installation method described herein requires coordination of tasks between workers. A safe installation is
dependent on alertness and coordination.
17. Before lifting the top frame to install uprights, always guy out and stake at least both corners of the side or end being
lifted. This will help maintain the intended footprint and will protect against uplift from the wind that could move or flip the
tent, causing damage to the tent and/or severe injury to workers.

Anchor products are of superior design and operate best within the parameters of these instructions. It is imperative
that the instructions be carefully read and COMPLETELY FOLLOWED. Please read installation instructions before the
installation or removal of this product. Installation instructions are available online at www.anchorinc.com or by calling
1-800-544-4445.
CAUTION:
1. For each installation, the installer is solely responsible for evaluating the site and the proper securing method
determined. Some soils require different staking or securing than that provided with the tent. Due to this variety of
soil conditions, these are the manufacturer’s suggested sequence of installation procedures. Anchor’s responsibility
is limited to the manufacture of the tent parts and materials. We are not responsible for methods that installers may
choose to erect and secure the tent to the ground.
2. The number of stakes suggested in the installation instructions do not necessarily meet all or any relevant codes
on the site of the tent installation. The number of stakes suggested will, in many cases, keep the tent erected,
however, due to various soil conditions; these stakes will be insuf¿ cient to keep the tent secure in high winds.
It is the tent installer’s responsibility, not the manufacturer, to determine the appropriate number of stakes to meet
the necessary wind loads on the site. Regardless of the number of stakes we suggest, we make no representation
or warranty as to whether this speci¿ c number of stakes will meet the local tent code. Anchor does not, nor can
it make any suggestions, representation, or warranties about the adequate staking required at each speci¿ c
installation site. Staking information provided in the installation instructions is not a suggestion about what is
necessary to meet a site-speci¿ c load.
For additional important information, consult: “The IFAI Procedural Handbook For the Safe Installation and
Maintenance of Tentage” and the IFAI Pocket Guide “Pullout Capacity of Tent Stakes”, both available from
the IFAI Tent Rental Division or on our website.
3. Inasmuch as the weather is unpredictable, good judgment and common sense must be incorporated within
installation guidelines. It is the responsibility of the tent installer/maintainer to determine the severity of the weather,
proper time and method of installation and/or erection and disassembly. Note: We recommend that snow and
ice be removed from the tent surface as soon as possible because accumulation will damage the tent
or fabric structure. Please consult with our Engineering Department about the maximum loads for each
