INEOS Grenadier Roof Load Bar Adapter | Leitner Designs

The Leitner Designs INEOS Grenadier Roof Load Bar Adapter is the simplest, strongest way to mount a rooftop tent on the Leitner ¾ or Full-Length ACS ROOF rack for the Grenadier. It adds a removable cross bar to your existing platform rack, creating a proper mounting point for an RTT without permanently modifying the rack. Remove it in minutes with 8 screws when you don't need it.

Each load bar is 60" long, 2" x 2" extruded aluminum with four T-slot mounting channels, paired with brackets laser-cut from 3/16" 6061 T6 aluminum for a completely flex-free install. A rubber pad on the bar prevents load shifting and road noise.

Available as a 1x (single bar adapter) or 2x (two bar adapter). Pair with Leitner's RTT-specific brackets for the cleanest tent installation possible.
