Introducing our same high security lock for the Reese Goose Box. Heavy 3/16" welded steel construction and is secured with a concealed shackle "puck" style lock. This lock full encompasses the coupler head of the Goose Box latch and will require power tools or a cutting torch to defeat. Accepts most all "puck" style locks (sold separately) which by design are completely bolt cutter proof. Time, noise, power tools or a cutting torch will be required to defeat our lock design which will eliminate most theft interest. Be sure to compare your coupler to the pictures here and DO NOT buy if it does not match. DO call us for clarification if you have any questions. Bright yellow powder coat. Made in America!
