Ideal for the tradie, these allow you to throw a ladder or a sheet of roofing tin on the top of the ute, so you can take almost anything almost anywhere! Provided you don’t need support under what you are carrying these are ideal.
However, when more support is required under your load, a Ladder Bar & Rack will do the job. These are available in Alloy from Ozrax or in steel from Tradesman.
