The product is described as suitable for off-road use and boat yard use, with webbing that resists UV exposure and weather. Best for boat trailers where a simple, one-person install is needed.
Who it’s best for: boat owners or trailer operators seeking a quick, secure lockout solution without fiddling with cables or adhesives. Why selected: it provides a durable magnetic lock with easy removal and stable magnetic force, reducing handling time during maintenance. Caution: magnetic keys are intended for specific actuator configurations; confirm your model matches A-60/A-70 before purchasing.
C CLINK 2 PCS Lock Out Key W/Magnetic
Better for households with two trailers or a shared facility where a backup key is beneficial. This 2-pack mirrors the single-key design with strong magnetic lock features and larger magnetic surface area for reliable hold. It’s designed to replace the silver factory key 34557 for A60 and A70 actuators and promises ease of installation and removal. Best for crews or families who want redundancy and faster service during yard work or winterization. Caution: ensure both keys align with your specific surge brake model to avoid incompatibility.

Buying Guide
- Compatibility: Confirm your trailer’s surge brake actuator model (A-60, A-70, A-75, A-84) and UFP type before purchasing.
- Lock Type: Magnetic lockout keys offer quick release and easier installation; manual keys can be more reliable where magnets are fragile or when surfaces are uneven.
- Durability: Look for UV-resistant webbing, corrosion-resistant coatings, and heavy-duty steel construction for outdoor use.
- Installation: Prefer one-person installation with minimal tools; avoid devices requiring tape, rubber bands, or clamps if possible.
- Multikey vs Single: If you park and store multiple trailers, a 2-pack or 4-piece kit can reduce search time and prevent lockout delays.
- Safety: Ensure the kit includes clear handling and removal instructions, and avoid forcing magnets off if they are firmly attached to metal surfaces.
FAQ
