horntools LockMagnet – Magnetic Rooftop Tent Anti-Theft Device
Product highlights:
- Tool-free installation: easy to install using magnetic special keys
- Low-profile design: minimal clearance between the roof rack and rooftop tent
- Versatile use: suitable for all rooftop tents with M8 bolts
- Robust construction: stainless steel security bolts for maximum stability
Maximum security for your rooftop tent – tool-free and robust. The horntools LockMagnet reliably protects your rooftop tent against theft, making it ideal for off-road adventures, camping or urban use. The magnetic security bolts hold firmly in place and prevent the rooftop tent from being removed without authorization.
The 1-piece set includes two security bolts and two keys. Larger sets can be purchased for added security. We recommend securing the rooftop tent diagonally across two mounting plates; for this, we offer the LockMagnet 2-piece set with 4 security bolts. For maximum security, choose the 4-piece set to secure your rooftop tent to all four mounting plates.
How to use the LockMagnet:
- Remove the nut from the rooftop tent bolt
- Slide the washer and anti-theft device onto the bolt
- From underneath, place the magnetic key onto it and tighten by hand
- Remove the key and store it in a safe place
- The rooftop tent is now protected against removal
