Dashboard Mounting Disks

This set provides four 4.5 inch (114.3 mm) heavy-duty adhesive disks designed for semi-truck dashboards. The extra-large diameter creates a broad mounting surface for suction-cup phone, tablet, GPS and dash-cam holders. Ultra-strong 3M adhesive forms a secure bond that resists vibration and temperature swings. A concave centre and integrated side grip improve suction hold and simplify installation or removal.

Universal Fit for Professional Drivers

Fleet operators and long-haul drivers who need reliable device mounting on textured or curved dash panels will benefit from the oversized footprint. The 3M adhesive requires a clean, smooth surface for maximum strength, so heavily porous or damaged panels may not hold. Users with small windshield-mounted arms or limited dashboard space should consider smaller alternatives.

Sustained Vibration Resistance

Under continuous highway vibration the large contact area distributes load evenly, reducing peel stress on the adhesive bond. The concave centre keeps the suction cup centred, preventing gradual drift that can occur on flat pads. Heat cycles inside a cab do not degrade the 3M layer once fully cured, maintaining grip through seasonal temperature extremes.

Questions about this item

What size suction-cup base will sit flat on the 4.5 inch diameter disk?

The disk measures 4.5 inches (114.3 mm) across, so any suction cup with a base up to that diameter will seat fully on the adhesive surface.

Will the 3M adhesive bond to a textured semi-truck dashboard without peeling?

The ultra-strong 3M adhesive is designed for rough road conditions and bonds securely to typical truck dash materials, but the surface must be cleaned and dry before application.

How can I confirm the concave center is gripping my mount correctly after install?

Press the suction cup into the concave center until it locks; the side grip holder lets you tug gently — if the mount resists movement, the disk is holding as intended.
