Proper Design Gripper Mats — Magnetic Sign Holder for Aluminum & Plastic Vehicles, Thin Reusable No-Glue Grip

Proper Design Gripper Mats™ let magnetic car signs hold fast to aluminum, plastic, and composite vehicle panels without glue or drilling.

Many newer cars, trucks and vans use non-magnetic materials for body panels, so traditional magnetic signs won’t stay put. Proper Design Gripper Mats provide a thin, high-friction interface that grips magnetic signs to non-magnetic surfaces, letting you use your existing magnets on taxis, fleet vehicles, or temporary advertising without damaging paint.

How do Gripper Mats make magnetic signs stick to non-magnetic panels?

The mats create a textured, high-friction contact between the magnet and the vehicle panel. You place a mat on the vehicle first, then the magnetic sign on top; the magnet presses the mat against the panel and the special surface resists sliding and lifting.

• Thin, conformable mat sits flat on aluminum or plastic panels
• Special grip material creates mechanical traction under the magnet
• No adhesives or permanent fixtures required
• Works with existing magnetic signs and taxi roof signs

Will Gripper Mats harm my paint or leave residue?

No — they are engineered to protect finishes. The grip surface is designed to hold magnets without sticky adhesives, so you can remove and reapply mats without peeling paint or leaving glue marks.

• No glue, tape, or chemical adhesive on the mat
• Safe for clear coats and factory paint when used as instructed
• Easily rinses clean if dirt accumulates
• Removable and reusable without scraping or residue

How durable are Gripper Mats and how do I care for them?

Gripper Mats are built for repeated use on commercial and private vehicles. The material resists wear from repeated attachment cycles and can be cleaned with mild soap and water to restore grip.

• Durable grip surface developed through years of testing
• Rinse or wipe with mild detergent to remove dirt and oils
• Store flat or rolled loosely between uses to maintain shape
• Designed to last through many sign placements and removals

Can I use Gripper Mats with any type of magnetic sign?

Yes — they are compatible with most standard magnetic car signs and taxi roof magnets. Because the mat only needs to provide friction under the magnet, it works with a wide range of magnet thicknesses and sign shapes.

• Compatible with magnetic car signs, taxi signs, fleet magnets
• Works with thin or thick magnets; larger magnets gain extra hold
• Useful for temporary advertising and rotating signage
• Ideal for aluminum, plastic, and composite vehicle panels

Who this is for: Proper Design Gripper Mats suit business owners, taxi drivers, delivery fleets, and anyone who relies on magnetic vehicle signs but drives aluminum- or plastic-bodied cars and trucks. If you need a non-permanent, paint-safe solution to keep magnetic signage secure on modern vehicles, these mats let you keep using your existing magnets without adhesives, drilling, or costly conversions.
