Gripper Mats™ by Proper Design | Magnetic Sign Holder for Aluminum Vehicles

Exactly what I needed and they work great!

I have an aluminum bodied truck and needed something stick signs to my doors for my new business. I got 4 packs of these and they work great for two 18" x 24" signs.

Finally a Solution for Magnetic Signs on Aluminium Vans

I struggled for ages with magnetic signs not sticking to my aluminium van. These Gripper Mats completely solved the problem. My magnetic business signs now hold firmly even on non-magnetic vehicle panels where magnets normally won’t stick. They’re clear, reusable, leave no residue, and don’t damage the paintwork. If your car magnet won’t stick to aluminium or plastic panels, these are an absolute must-have. Highly recommend Gripper Mats for magnetic signs.

I was given great customer service by Proper Design and the Gripper Mats are perfect for what I need. Thank you.
