VHB Adhesive Magnet Mounting Discs

Turn any non-magnetic roof into a magnetic mounting surface. The semi-permanent setup that lets you remove and transfer your mount whenever you want.

This set of four powder-coated steel discs sticks straight to fiberglass, aluminum, boat decks, and other surfaces that magnets cannot grip on their own. Each disc comes with genuine 3M 5952 VHB adhesive pre-applied. Stick the discs down once, then drop your magnetic mount on top. Lift it off and reposition it any time.

The powder coating protects the steel from corrosion and keeps a clean, durable finish built for the outdoors.

Each disc is pre-drilled with M6 holes if you ever want to bolt down instead. For most installs, the VHB adhesive provides more than enough strength when properly applied.

Pairs with Rubber Coated Magnets Rubber Coated Magnets are sold separately. Stick the discs to your roof, set the magnets on top, and you have a strong semi-permanent hold with easy removal.

Move it between vehicles The discs stay bonded where you place them. Install discs on more than one vehicle or spot, then move the mount with the magnets attached wherever you need it.

Curved or angled roof For curved or uneven surfaces, pair with Swivel Leg Adapters so each foot sits flush for full contact.

Installation

These instructions are for the magnet and VHB backed mounting discs. Magnetic feet are sold separately.

  1. Feed the bolts (blue Loctite already applied) through the openings at each of the four feet on the TRIO mount.
  2. Thread the bolts into the magnets and tighten with the supplied allen key.
  3. Attach one VHB backed disc to each magnetic foot. Confirm each is free of debris.
  4. Confirm your mounting surface is smooth and non-porous. For best adhesion, lightly scuff the surface with a scotch pad. Do this at your discretion, as scuffing will mark the finish. Clean the scuffed area with the included isopropyl alcohol wipes.
  5. Remove the red VHB liner. Carefully set the mount with the exposed discs onto the cleaned surface. Point the TRIO logo and dish cord toward the back (trailing edge) of your vehicle, boat, or RV.
  6. Apply firm pressure through each mounting foot for solid adhesion. If possible, place a heavy object on top of the mount for 24 hours to optimize the bond. Ideal application temperature is 70°F to 100°F.
  7. Slide the Starlink dish onto the mount until it clicks firmly into place. Confirm it is secure. You are online.

Removing the mount
Lift from the rear of the mount itself. Do not use the Starlink dish as a lever.

For full adhesive guidance, refer to the 3M installation instructions on page 7.

Can I move the VHB Discs between vehicles?

The VHB Discs stay bonded in place. You can lift the mount with the magnets attached and set it on another spot or vehicle that has discs installed.
Do I need to drill to install the VHB Discs?
