TeraFlex JT Uinta Cargo Bed Rail System. It is built well and is very heavy duty, made of extruded aluminum and has 4 hooks. No drilling required and it will attach to the existing holes in your Gladiator's bed. It is super easy to install. I purchased it one year ago but I just sold my Gladiator and I have no need for this any longer. It is in excellent condition, no damage, no scrapes, no oxidation, paint in great shape. Complete set with all mounting screws. This unit will cost over $400 new. If ad is up, the item is still available.
