This versatile coupler lock accommodates three different sizes of couplers: 1-7/8", 2" and 2-5/16". Some of its innovative features include a horizontally-bent, chrome-plated shackle protected by a corrosion-resistant, nickel-plated housing. For heightened security, this coupler lock provides an anti-drill pin and a bolt-blocked locking system. Multiple locks will be keyed-alike so that the same key can be used to access all your trailers.
Fastway coupler locks work on many different styles of trailer couplers as shown below.
