Vacuum Cups form the base of every product we offer

They are used to mount an accessory or modular base to the roof, rear or windscreen of your car, van, lorry, bus... Anything with a smooth surface.

Our vacuum cups aren't in your bathroom.

They are not your usual 'stick to the wall' bathroom suction cups.

Our vacuum cups are tried and tested in industry, used to lift large glass window pane's on construction sites.

Activated using the plunger on the side, the vacuum cannot be broken without manually lifting the tabs on the cups.

Capable in all weathers

No matter the weather Mount Evo vacuum cups work as intended. regardless of rain, snow or sun, our vacuum cups won’t suffer a loss in suction. Water acts as a lubricant sealing in the vacuum and doesn’t affect the force applied. Ensuring maximum vacuum even in adverse conditions.

How do the cups work?

Mounting the cups:

The vacuum cups can be mounted to a smooth surface by pumping the attached plunger repeatedly

Vacuum Indicator:

Once the yellow indicator band on the plunger is no longer visible the vacuum cup is secure.

Removing the cups:

The cups can be dismounted and removed by simply pulling the tab on the rubber cup, or lifting the edge.

A basic theoretical vacuum force equation is as follows:

Ft = ΔP x A

Ft = 10 x (π x 3^2)

Ft = 282.78 lb (128.7 KG)

A = Area (πr²)

ΔP = Atmospheric - Vacuum pressure

Atmospheric Pressure = 14.7 psi

Vacuum pressure = 4.7 psi (approx)

Our 6inch vacuum cups therefore have a theoretical break force of 128.7 KG.

This would mean that our Solo bike rack has a total theoretical vacuum force of 514.8KG (128.7 x 4).

Obviously this doesn't take into account external losses such as altitude and surface friction. But what it shows is that our vacuum cups are incedibly powerful and more than capable of carrying your sporting equipment!
