CLINK Works Great
I didn't know about how a large trailer surgery brake worked when I bought it. The key that came with it didn't work well. This clink with the magnet fits perfectly and magnet holds it in place whether in place to disable the brakes, or disengaged to allow brakes to work.

Trailers with surge brakes need this.
Works great to lock out surge trailer brakes when backing. Strong magnet and bright color make it easy to store and locate on the trailer when needed.

Life saver for our Trailer for the boat
The C CLINK Surge Brake Lockout Key with Magnetic Lock Out Key is an absolute lifesaver. We encountered a situation where our trailer with a boat wouldn't go in reverse, and this product saved the day. The compatibility with UFP Type Surge Brakes, including A-60, A-70, A-75, and A-84, makes it versatile and suitable for various boat trailers. The magnetic lock-out key feature is ingenious, providing a convenient and reliable solution to overcome braking issues in reverse. The ease of use and effectiveness of this lockout key from C CLINK not only resolved our problem but also saved us from potential headaches and expenses. If you have a boat trailer with UFP surge brakes, I highly recommend keeping the C CLINK Surge Brake Lockout Key handy – it's a small investment that can prevent significant issues.
