The full rundown
A 4 pack of 76mm 3M adhesive steel discs that give a magnet mount something to grab on aluminium, fibreglass and other non-magnetic roofs.
Why it works
- 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.

How it works
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.
What it suits
- 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.
Fitting it
Difficulty: 1/5 (Easy). Clean, peel, and press; full adhesive cure achieved after 24 hours.
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.
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.

What owners say
G'day, we're Treklo
We're a handful of blokes in Geelong who spend our weekends in utes, vans and campers. We got sick of 12V gear that gave up a few trips in, so we started making our own and running it in our own rigs first.
