Aluminum Locking Roof Rack Cross Bars
Discount Ramps is now pleased to offer the Aluminum Locking Roof Rack Cross Bars. These locking rooftop cross bars by RAGE Powersports are for vehicles with an existing roof side rail system. The cross bar features adjustable clamps that slide along the 4 foot by 1.25 inch wide cross bars to accommodate a wide variety of vehicle roof widths. Designed to clamp on existing vehicle roof side rails, the locking roof rack cross bars provide an extra 120 pounds of capacity for carrying luggage, equipment or camping supplies. For model number RLB-57045 to properly be effective, the side rails of your vehicle must be from 1.25 inches high x 1.75 inches wide with at least 2 inches of clearance between the top of the rail and the vehicle’s roof; more room would work the best. Also, your vehicles side rails should be 43.25 inches apart or less for the aluminum cross bars to most effective. A key locking mechanism is included to prevent theft, and a rubberized flexible grip that form-fits to the side rails keeps your RAGE Powersports aluminum rooftop cross bars safe and secure. With an easy turn knob system included, the installation of the RLB-57045 is quick and painless. This cross bar system completes the standard roof rails by adding additional storage and flexibility to your vehicle. These crossbars add an additional 120 pounds of security to the roof of your car. These cross bars can hold ski/snowboard attachments, bike attachment, luggage baskets, roof boxes and car top boxes. As with just about everything Discount Ramps sells, there is a one year manufacture’s warranty with this system.
The Discount Ramps model number for the Aluminum Locking Roof Rack Cross Bar system is RLB-57045. This aluminum cross bar system measures 50 inches in length and 1.25 inches in width, with a 3/4 inch height. It works with a vehicle’s side rails up to 1.75 inches wide and 2 inches high, and they can be up to 43.25 inches apart. A lot of these racks shift and move around after they are installed, but the lockable aluminum prevents any shifting of the cross bars. These key-lockable aluminum cross bars come with adjustable width, and sliding clamps that feature easy turn knobs to make clamping them down a breeze. Installation is very fast with this system, and it has a flexible rubber padding that form fits to the side rails for added protection against scrapes and scratches on the roof of your vehicle.

I’m interested to buy the roof rack (RLB-S704S), but I prefer to looking for it in Jakarta-Indonesia. Do you know where I can find it in Jakarta-Indonesia?
I just bought these and feel ripped off. Very cheaply made probably in China or Indonesia. They do not even come with instructions. I called Discount Ramps and the best that they could do is direct me to their web site. The instructions are there. To bad they could not even print out a page and enclose it in the box. Be careful how you pull on the ends. They come apart.
Hopefully it will last a year.
