50’ Navi-Trac Frame Terminology
INTRODUCTION:
The NAVI-TRAC frame configuration is based on
the hip roofed square tent shown at 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 appropri-
ate ridge/eave bars (see above). 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 cor-
ner 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 1 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.
