What through hole magnetic mounting pad sizes are available?

Shop for Magnetic Mounting Pads

Width

Through hole magnetic mounting pad width 30mm and 39mm The width of a through hole magnetic mounting pad refers to the two shortest sides of the magnetic mounting pad and can range from 30mm (1.18″) to 39mm (1.54″).

Depth

Depth of a through hole magnetic mounting pad 7.5mm and 12mm The depth of the through hole magnetic mounting pad is the distance between the bottom of the magnet and the top of the back plate.¬†It can range from 7.5mm (0.295″) to 12mm (0.47″).
Thin through hole magnetic mounting pad A thin through hole magnetic mounting pad is better for a car-roof sign as there will be no gaps between the car roof and the car sign.

Length

Through hole magnetic mounting pad length 75mm and 100mm The length of the through hole magnetic mounting pad can range from 75mm (2.95″) to 100mm (3.9″). A longer magnetic mounting pad will be beneficial for long advertising signs as the magnet will be able to hold a greater proportion of the sign securely.

Through hole diameter

4mm diameter through hole on a through hole magnetic mounting pad The through holes have a diameter of either 4mm (0.16″) or 5mm (0.2″).

Magnetic pull

Through hole magnetic mounting pad magnetic pull 3kg and 12kg The magnetic pull of a through hole magnetic mounting pad ranges from 3kg (6.6lb) to 12kg (24.46″)
Wonkee Donkee says "The magnetic pull is the maximum weight of ferromagnetic material the magnetic mounting pad can hold, this is not determined by its overall size. This means that a large magnet does not necessarily have a larger magnetic pull than a small magnet"
Lighting fixture with labelled position for magnetic mounting pad A larger through hole magnetic mounting pad will have a greater overall surface area allowing more contact between the magnet and the ferromagnetic material. Therefore, the magnetic mounting pad will be able to hold larger objects more securely.
