RAISED RAILS/ RAISED SIDE RAILS
A raised rail, running from the front to the back of the vehicle. Raised enough off of the roof so that your hands can wrap around the rails.

FLUSH RAILS
Like the raised rail, the flush rail runs from the front to the back of the vehicle. Differing in heights, sometimes few inches tall, they are considered flush as there is no space between the car and top of the rail.

FIXED POINTS
Small holes, perhaps hiding under little tabs, found either along the inside of a flush rail or on the top of the roof itself. These holes provide a fixed point where roof rack towers/feet can be attached.

TOWERS/FEET
A part of the roof rack. The cross bars attach to the top of the towers. The fit kit attaches underneath the towers. The towers hold the cross bars up.

CROSS BAR
Square, round or “airplane winged” in shape, the cross bar attaches to feet/siderails  and spans across the roof, right to left, usually door frame to door frame.

FIT KIT
The fit kit allows for the towers to attach to the car. Consists of  four clips and  four pads, specifically designed for the roof line of your vehicle.

CLIPS
The part that grabs the door frame.

PADS
The rubber part that makes direct contact with the roof of the vehicle. The pad attaches to the bottom of the foot/tower.
