DeMello Off-Road Utility Bed Bars are made from 1.75" round tube. Each bed bar comes with three tabs that can be used for lights, antenna or anything else you can think of. DeMello Off-Road Utility bars are the first to offer a totally adjustable Hi lift mounting system. This allows you to run any brand of off road jack you want! The Bed Bar is firmly bolted to the bed using the inner rails of the bed using either 5/16 bolts and nuts.
