possible (towards the outer 4 corners of the Product).

able, they should be set in the widest position (far-
thest apart from each other) that will accommodate
the attachment of the Product; this positioning will
make for better load distribution.

shape Blocks (7) on the Platform between two proper
Middle Bars and ride right above vehicle’s roof rack
crossbars, then attach the Connection Brackets (6)
to the Platform and Vehicle’s crossbar using U-shape
