The perfect solution to replace, upgrade or secure your tent to additional crossbars. Freespirit's mounting hardware kit makes installation a snap with sure grip rubber coated u-mounts that fit any style of cross bar up to 3 1/2" wide and 1 1/2" thick. Tool free installation using a star knob with built in nut. Please note, the sliding plates included in this kit are only for Aspens or newer models of hardshell tents. For thicker cross bars simply replace your 2" M8 hex head bolts with longer ones.
