A great idea and well executed by the folk at Front Runner. This set can be used to quickly release the tent from a platform rack or load bars. Solidly made, we've set up quite a few of these and they work well. 

This is the 6-piece kit which includes an Autohome channel set. You'll also need the reinforcing Hard Shell Tent Support Channels to make it all work. 6 is nice to have for extra stability, especially on the extra long tents.

We strongly suggest pairing the set-up, if you can with the Box Lift hoist system - if you have the space to fit your vehicle with tent on it into a garage or carport this certainly makes light work of the job. 

These raise the tent up a bit, off the rack, which also gives you the vertical space you need to mount a range of accessories to the side rail of the roof rack, so that's an extra bonus to using the quick release system. Such accessories includes the awesome Front Runner table which is in itself a good reason for using the system.

What Front Runner have to say:

Do you have limited garage clearance? Maybe you just don’t want to keep the tent on your vehicle at all times. Front Runner's Quick Release Tent Mount Kit gives you the freedom to mount or remove the tent in seconds, and with no tools. The 4 lockable latches give you safety and added peace of mind.

• Once these brackets are installed on a Front Runner Rack, no tools are needed to remove or install a roof top tent.
• Simply release the tabs on the 4 latches and lift the tent away.
• This strong and rattle-free mounting system is built off-road tough for use with Front Runner Racks.
  
• 4 low profile base brackets are bolted to a Front Runner Rack while 4 self-aligning bushes are secured to the tent base channels using the supplied plates.
  
• Secures in place with 4 latches with safety catches. 
• The brackets are small, unobtrusive and can be left on the roof rack when the tent is not mounted.
  
• No tent modification required.
• Removed tents can be stored on the ground, raised slightly off the floor by the supplied steel bushes.
• Supplied with all required mounting hardware.
• Fitting instructions are included.
