This rack features a TESTED LOADING CAPACITY of 350 lbs.
Our design of the Extendable Top Bars allows the X35A to fit in different sizes truck beds. 
Top Bar Extension: Min: 51'' Max: 71'' Product Height: 30.5'' to the top, 28'' to the top cross bar.
The Rope Hook on the side of all four uprights provides the security for tying the tools or loads.
This rack is powder coated in the color of black and white  

This unit bolts on the rail of your bed, it fits most trucks as long as you don't mind bolting. Again, Bolting means DRILLING HOLES in your vehicle, please do not proceed if you don't intend to make holes on your car.  

The extension top bars fit all the full size or half cab truck beds.
The upright plate is a flat "L" shape base which has three drilling holes for flexible installation, and you only pick two that fits your truck; and yes, we provide the total of 8 bolts and washers in the hardware package for installation.
As of now, some compatibility cases we have heard are:

1. Some tool boxes & Tonneau covers will affect the installation of this unit;
2. Bed rail top made of fiberglass instead of metal for some rare truck models like F-150 super-cab, customers complain it not sturdy for heavy-duty purpose after making holes;
3. There are track system installed on the inner bed-wall like the New Toyota Models which blocked our mounting plates;
4. Bed width is too small for the minimum extension of 51''.
