Insert Cage Nuts Into Rail Holes
In addition to using the included square hole adapter brackets, install cage nuts
at specific locations in the front and rear RETMA rails. The Sun Rack II rack
shipping kit contains a cage nut insertion tool that helps install the included M6
cage nuts into square RETMA rail holes.
Retrieve a cage nut and align it with the desired RETMA rail hole from inside
Ensure that the lips of the cage nut face the outside of the rack.
Hook one lip of the cage nut in the square rail hole.
Insert the tip of the cage nut insertion tool through the rail hole and hook
the other lip of the cage nut.
Using the insertion tool, pull the cage nut through the hole until the other
lip snaps into place.
