FAQs
Q1: How does the magnet work?
A: Our 3.5K trailer magnets adopt high-strength rare earth magnet core. It forms a tight magnetic attraction with the iron metal surface of the trailer through physical magnetic force. No chemical adhesion or extra fasteners are needed. The strong magnetic field provides lasting and stable holding power to fix lights, sensors and accessories firmly on the trailer body, ensuring reliable connection during driving and vibration.
Q2: How to install the magnet?
A: Installation is tool-free and super simple. First, clean and dry the adsorption surface of the trailer to remove dust, oil and rust. Then directly attach the magnetic product to the smooth iron position where you need fixation. Press firmly for 3-5 seconds to ensure full contact. It can be installed, adjusted or removed in seconds without drilling, welding or gluing. You can also reposition it freely according to different usage needs.
Q3: What is the advantage of magnetic brake magnet?
A: The 3.5K magnetic brake magnet has multiple core advantages for light-duty trailers. Firstly, it features ultra-fast mounting without damaging the trailer structure, protecting the vehicle paint and body completely. Secondly, it has strong load-bearing up to 3500 lbs rating, stable adsorption even on rough roads and high-speed driving with no falling off risk. Thirdly, it is waterproof, rust-proof and weather-resistant, adapting to outdoor rain, snow and sunlight exposure for long service life. In addition, it is reusable and portable, suitable for cross-trailer switching use, greatly reducing maintenance and installation costs for users.
Q4: Is the magnetic accessory suitable for all 3.5K light trailers?
A: It fits all iron-surfaced 3.5K utility trailers, RV trailers, boat trailers and cargo trailers. It is not applicable to full aluminum or fiberglass trailer surfaces without iron metal components.
Q5: Will the magnet scratch the trailer surface?
A: Absolutely not. The product is designed with anti-slip and anti-scratch protective padding on the contact bottom. Combined with smooth waterproof coating, it will not leave marks, scratches or dents on the trailer paint during adsorption and removal.
Q6: Can it be used in rainy and harsh outdoor environments?
A: Yes. All 3.5K trailer magnetic parts are made with rust-proof steel shell and professional waterproof & shockproof coating. It can resist rain splash, sunlight corrosion and road bump pressure, perfectly adapting to long-term outdoor working conditions.
