3M Adhesive Mounting Discs for Magnets - 4 Pack

Take your Starlink setup anywhere with the 3M Adhesive Mounting Discs for Magnets - 4 Pack. Purpose-built for use with Starlink Magnet Mounts for Gen 3 and Mini, these heavy-duty 76mm discs create a magnetic-friendly surface on any non-metal area - perfect for fibreglass, aluminium, or composite panels.

Whether you're camping off-grid, travelling in your caravan, or setting up a Starlink system on your boat, these discs make it easy to mount and move your Starlink gear safely and securely. They can also be used for other antennas, lights, or accessories that rely on magnetic bases.

Essential Benefits

• Designed for Starlink magnet mounts - built specifically for Starlink Mini and Gen 3 magnetic bases, giving a solid anchor point on non-metal surfaces.
• Strong magnetic hold - engineered from high-permeability soft steel that channels magnetic fields efficiently for 2-5x stronger grip than standard metal.
• 3M VHB industrial adhesive - delivers a long-lasting bond on flat, clean surfaces without screws or tools.
• Weather-resistant construction - built to withstand Australia's road, heat, and coastal conditions.
• Slim, flush fit - low-profile 76mm design sits cleanly under your Starlink mount or antenna base.
• Universal versatility - also suitable for mounting GPS, LTE, UHF, CB, and marine antennas, or any magnetic accessory.

Functionality

The 3M Adhesive Mounting Discs make Starlink Magnet Mount installation quick, easy, and secure - even on fibreglass, aluminium, or plastic. Simply peel the backing, stick the disc to a flat surface, press firmly for 30 seconds, and leave it to cure for 24 hours.

Once installed, the discs act like steel - allowing your magnetic Starlink base to snap on instantly and hold firmly in place. The high-permeability metal ensures maximum grip strength, while the 3M VHB adhesive keeps everything locked down through vibration, weather, and travel.

Compatibility

• Starlink Mini magnet mount
• Starlink Gen 3 magnet mount
• Other uses - LTE, GPS, UHF, CB, and marine antennas, LED lights, or any magnetic base accessory.
• Surfaces - fibreglass, aluminium, composite panels, polycarbonate, and flat plastics.
• Applications - campervans, caravans, RVs, 4WDs, trailers, boats, and off-grid setups.

Installation Difficulty

1/5 (Easy) - clean, peel, and press; full adhesive cure achieved after 24 hours.

Adhesive Curing Advice

To ensure a secure and permanent bond, allow 24 hours for the 3M adhesive to fully cure before attaching any magnetic mount.

• Clean and dry - install only on clean, dry, and flat surfaces.
• Apply pressure - use firm, even pressure for 30 seconds during installation.
• Warm the surface - in cold conditions, gently heat the area to improve adhesion.
• Be patient - failure to wait 24 hours may result in a weak bond and possible failure.

Features

• High magnetic efficiency - soft steel construction boosts magnetic holding strength up to 5x compared to normal steel or curved surfaces.
• 3M VHB adhesive layer - industrial-grade adhesive ensures long-term reliability and weatherproof bonding.
• Smooth, flat finish - guarantees full magnet contact and consistent performance.
• Corrosion and UV resistant - designed for all-weather use across land or marine setups.
• Compact size - 76mm diameter with ~2mm profile.
• Tool-free installation - no drilling or modifications required.
