Dual Lock is a security lock that
helps prevent your trailer from being stolen from the boat ramp or even from
outside your home. Notice how Dual Lock covers the nut under your two ball to
prevent the nut from being undone.
Most trailers are
stolen from either unfenced or unsecured storage areas. Some small trailer locks
are easy to break with a good whack from a standard hammer.

Dual Lock is mate from 8mm solid
steel plate and is cadmium plated to prevent rust.
