Over Time, The Fitters here at Tough Touring have seen manufacturers of Modern Dual Cab Utes 'leave out' roof rack fitting points over the cabin of most modern Dual Cab 4x4, Probably due to market competitive pricing, combined with incrased pressure on larger and larger air bags inserted into the roof cavity. 
Tough Touring has developed a safe and strong way to install a dual cab roof rack - and included the Components to allow you to install your rack with inverted Dome Nuts on the inside - Allowing proper deployment of air bags in the event of an accident, and also fixing your roof rack onto the cab with through bolt strength. 
 
These Kits are put togehter using Forch 8.9 High tensile Dome nuts, and include a tube of sikkaflex sealant and all required hardware. 
Roof lining needs to be removed to install this kit, we do not include instructions... Some notes below for professional Fitters only.
