The Rack Frame :
This Z4 luggage rack is manufactured from 25mm/ 1" 6063-T5 tubing this is an aluminium and magnesium alloy ( it will never rust ) As a result the rack frame weighs only 1.672kg / 3.6lb perfect for the Z4's boot/trunk lid. The cross bars are machine welded in place to ensure consistency, the rack is powder coated black. The rack measures 900x420mm / 36"x17"
The Supports :
The rack is secured to your Z4's boot/trunk lid using three 115mm vacuum cups, rated by the manufacturer as capable of holding an 18kg/40lb load each. These are very different to suction cups.
Vacuum cups employ the force of atmospheric pressure to grip a surface: When a vacuum exists between the cup and the surface on which it is attached, the weight of Earth's atmosphere holds the cup in place with incredible force. Unlike suction cups that produce a vacuum as they pull away from the surface, Revo-Racks vacuum cups use a hand-actuated pump to efficiently remove air from between the rubber pad and the attaching surface thus creating a much more reliable hold. Because the full face of the pad is brought into contact with the surface, distortion is reduced, allowing the cup to be used with very little risk of damage.
The Revo-Racks vacuum cup's pump feature a plunger with a red line, which serves as a vacuum indicator. Introduced in the1960's, this safety device is still recognized as one of the most reliable warning systems available. A few strokes of the plunger evacuate the vacuum pad, causing it to seal securely to the attaching surface. When the cup is attached completely, the plunger stops moving and the red line is hidden within the pump. A visible red line indicates if air has leaked back into the pad, making vacuum insufficient to use the cup. However, if the red line becomes visible while the cup is in use, a check valve allows the user to re pump the cup without losing the remaining vacuum
