A step-by-step guide to mounting 6 Channel Crossbars on your Roofnest, with spacing tips, torque checks, and load-rating advice for rooftop tent gear.

Quick answer

Mount 6 Channel Crossbars by attaching the towers to your Roofnest accessory channels or directly to the shell of a Condor 2 or Falcon 3, then set the bars parallel and evenly spaced before torquing hardware. Use the six T-slots in each crossbar to bolt gear with M8 hex-head bolts. Check your vehicle and tent load ratings before adding weight.

Before you start: tools, fit, and load limits

Gather a tape measure, a hex key set that includes M8, a torque wrench if you have one, and a helper for lifting bars into place. The 6 Channel Crossbars attach to the accessory channels on Roofnest aluminum tents and directly to the shell of the Condor 2 and Falcon 3 tents, so confirm which mounting style your tent uses before you begin. You will also need to know your roof rack's dynamic and static load ratings, plus your tent's own weight, because those numbers set the real ceiling for everything you carry. If your rack or vehicle manual does not list a rating, treat that as a decision limitation and keep added gear minimal until you can confirm it.

Plan crossbar spacing around the load, not the look

Spacing changes how stable a rooftop tent or long cargo box feels at highway speed and on washboard roads. Wider spacing spreads the load and reduces flex, while narrower spacing can leave long items unsupported at the ends. Measure the mounting points on your tent or gear first, then mark the bar positions on the rack so both bars sit parallel and at the same height. Keep the bars perpendicular to the vehicle's direction of travel unless your rack manufacturer specifies otherwise.

Installation steps

Confirm the mounting interface: Check whether your tent uses accessory channels or a shell mount. The 6 Channel Crossbars attach to accessory channels on Roofnest aluminum tents and directly to the shell of the Condor 2 and Falcon 3. Mistake to avoid: buying shell-mount hardware for a channel-mount tent. Match the hardware to the tent before you start.
Position the towers on the rack or tent: Set both towers at your measured spacing and make sure they sit square to the rack. Hand-thread the fasteners so nothing cross-threads while you adjust. Checkpoint: the two towers should be parallel and at equal height before you tighten anything.
Set crossbar spacing and level the bars: Slide each crossbar into the towers and measure from a fixed point on both sides to confirm even spacing. A helper makes it easier to hold the bar level while you check. Mistake to avoid: eyeballing spacing. Uneven bars make a rooftop tent sit crooked and can stress the mounting points.
Tighten hardware in a cross pattern: Snug the fasteners in an alternating pattern rather than fully tightening one side first. Use the torque value from your rack or tent documentation if it is provided. Checkpoint: re-check spacing after tightening, since hardware can shift the bars slightly.
Mount gear using the T-slots: The six T-slots in each crossbar accept a hex-head M8 bolt, so you can bolt accessories directly to the bar. Use the slot that puts the load over the strongest part of the bar. Mistake to avoid: overloading one slot. Spread heavy items across multiple slots and both bars.
Verify load rating and re-torque after the first drive: Compare the combined weight of bars, tent, and gear against your rack and vehicle limits. After your first trip, re-check the hardware and re-torque as needed. Next step: if you are adding insulation, fit it after the crossbars are set so the liner is not disturbed.

Product facts

6 Channel Crossbars: The Crossbar towers attach to the accessory channels on Roofnest aluminum tents and directly to the shell of the Condor 2 and Falcon 3 tents. The six T-slots in each crossbar accept a hex-head M8 bolt for mounting gear. This tells you whether you need channel nuts or a shell mount, and it confirms the bolt type to buy before installation day.
Condor 2 Series Tent Insulation: Condor 2 Series Tent Insulation is designed specifically for Condor 2 Series tents, with all windows, doors, pockets, and HVAC pass-throughs accounted for. If you plan to run insulation, install crossbars and any roof gear first so you are not working around a fitted liner later.
