Roof Rack
Installation Instructions
CAUTION: Do not use the mounting hardware contained in this roof rack kit for installation
on Fiberglass or Composite Plastic surfaces. Supplemental hardware pack, part# HWDSTC-
UV, is required for installation on such non-metal surfaces. Please contact the Distributor
from whom the rack was purchased or contact the Perrycraft Customer Service Dept at 800-
777-7081 to obtain the necessary supplemental hardware pack if installing this roof rack
on a Fiberglass or Composite Plastic surface.
Warning: External roof racks do not increase the GVWR of the vehicle. Total occupant and
cargo load should not exceed the vehicle manufacturer’s rated vehicle capacity. Maximum
load for this rack is 75 lbs. evenly distributed on the crossbar assemblies. Maximum
weight of loads placed directly on the roof slats is dependent on the particular vehicle roof
structure and construction. Large or flat items such as plywood panels or small water craft
can trap air and cause wind lift. Extreme caution should be used when transporting such
items, taking into consideration road conditions, vehicle speed, load securement methods,
etc. Molded car top luggage carriers or pods should be placed between the rack crossbars
and secured directly to vehicle body. Perrycraft, Inc. cannot assume responsibility for
improper rack installation, exceeding rack load limit, load securement methods, vehicle roof
strength or wind lift.

INSTALLATION:
1) As this DynaSport “universal” roof rack is designed to fit several different vehicles, the
“bow/curvature” of the rails may or may not exactly match the roof contour of a particular
vehicle. The rails should be “dry fit” to the roof panel before installing. Carefully place
one of the rails (without end supports or center support posts) on the vehicle roof in
the approximate location to be installed. The curvature of the rail should approximate
the roof contour. If the rail is under-curved and there is more than a 3/16” space between
the ends of the rail and the vehicle roof panel, or over-curved and there is more than a
3/16" space between the center of the rail and the vehicle roof panel, “bench adjusting”
the curvature of the rails is required. Adjust by suspending the rail between two points
(4x4 wooden blocks, two tables, etc). To increase the curvature, start with the rail upside
down; to decrease the curvature, start with the rail right side up (see appropriate
illustration below). With hands spaced shoulder-width apart, apply sufficient pressure
to the rail to increase or decrease the curvature as desired. Repeat this process for both
rails.
Important Note: While made of extruded aluminum, the rails are heat-treated for added
strength. Therefore, several applications of adequate "springing" pressure may be required
to modify the curvature of the rails.
