  • Recommended Trailer Coupler Locks for Wide Coupler Security
    For your Atwood Channel Tongue Trailer Coupler 80060, I recommend the Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers # FA86-0015-318 or the Master Lock Coupler Lock for 1-7/8", 2", 2-5/16" Couplers # ML389DAT are both good options. The latter doesn't have any restrictions of the width of the coupler.

  • What is the Strongest Coupler Lock and Locking Pin That Will Fit My Square Coupler
    I do have a recommendation for a coupler lock for your square coupler. I recommend the Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers # FA86-0015-318. I recommend the Fastway Universal Lock because it is made to fit various couplers, including square ones like yours. Also, the bolted lock is internal to prevent prying and the key mech is rounded to make it more difficullt to pick. Finally, it fits couplers up to 4" wide and the shackle is 6" long top to bottom,...

  • Recommended Hitch Lock and Coupler Lock Incorporating Safety Chains
    I am not aware of any chain lock. We do have some ball mounts like the B&W Tow & Stow 3-Ball Mount - 2" Hitch - 5" Drop, 5-1/2" Rise - 10K - Black # BWTS10048B which when using a locking hitch pin like # 63232 will secure the shank and ball to the hitch receiver. The Curt Channel Style # C45900 will also secure the ball and mount using # C23556. If you want to secure a coupler to the ball you can use # BD580403. If you really want to secure your chains, you can use a cable lock like...

  • What Coupler Lock Fits the Demco Trailer Coupler # DM99VR?

  • Can the Master Lock Trailer Coupler Lock # ML389DAT be Keyed Alike
    I do have a solution for you, but the Master Lock Trailer Coupler Lock - 1-7/8", 2" and 2-5/16" Ball Couplers # ML389DAT that you referenced does not have the option to order the locks so that they are keyed alike. For a coupler lock that fits 1-7/8", 2" and 2-5/16" couplers and can be keyed alike I recommend going with the Fastway Universal Trailer Coupler Lock # FA86-0015-318. This is one of our most popular coupler locks and has received excellent reviews from customers. We have multiple...

  • Will the Master Lock Coupler Lock # ML389DAT Fit a 4 Wide Trailer Coupler
    We do have some options for you but the Master Lock Trailer Coupler Lock # ML389DAT that you referenced has a max coupler width of 3-1/4" so your coupler will be a little too big for it. For a coupler lock that can accommodate a 4" wide coupler you could use the Fastway Universal Coupler Lock - # DT25013KA or the etrailer.com Coupler Lock - # e98895. I have linked review videos for each lock so that you can get a good idea how they operate.

  • Locking Hitch Pin, Coupler Lock and Coupler Latch Lock for 3 Inch Receiver
    The span of the hitch locks included with the Reese Tow and Store lock kit don't have a span long enough to work with a 3 inch receiver. However, you could piece together a kit that'd work for you. For the receiver lock, I'd recommend the Draw-Tite # BD580412 which offers a 4 inch span and uses a high security key. For the coupler lock, use # FA86-0015-318 and for the coupler latch lock, use # 605DAT. ..

  • Recommended Trailer Coupler Lock For Demco Trailer Coupler # DM69FR
    I have another option for you but the EZ Lock Trailer Coupler Lock for 1-7/8", 2", 2-5/16" Bulldog Collar-Lok Couplers # BLTL-20 you were looking at is only confirmed to fit the Bulldog Collar-Lok couplers and will likely not work with your Demco Trailer Coupler # DM69FR. Instead I recommend the Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers # FA86-0015-318 which is the same concept but is adjustable and will work perfectly on your # DM69FR.

  • Recommended Adjustable Coupler Lock for Tight Fit
    The Blaylock EZ Lock Trailer Coupler Lock for 1-7/8", 2", and 2-5/16" Couplers - Aluminum # BLTL-33 isn't necessarily designed for a tight fit. It is designed to give you a couple different pin location options but the latch is really all that keeps it in place tightly as the pin just prevents removal. If you want a tighter lock, I recommend the Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers # FA86-0015-318 which allows for many adjustment points for a precise...

  • Recommended Lock for Demco eZ-Latch Coupler
    To secure your PJ Trailer that's equipped with the Demco eZ-Latch Coupler # DM14040-81 I highly recommend the Fastway Universal Trailer Coupler Lock # FA86-0015-318, which doesn't require a lip on the coupler for a proper connection. This is a heavy-duty lock that uses a ball and shackle to prevent potential thieves from coupling their truck to the trailer and taking off. Its hardened chrome-plated construction will resist corrosion and the bolt-blocked locking system prevents the lock...

  • Coupler Lock Recommendation for Trailer with 4 inch Wide Coupler
    We have a solution that will work great but the part # BLTL-20-40D would not be what you'd need as it is designed to fit a Bulldog Collar Lok coupler and is only 3-3/16 inches wide. The # FA86-0015-318 would instead be what I recommend as this fits all standard coupler sizes like what you have.

  • What is the Difference Between Fastway Coupler Locks FA86-0015-318, FA86-0015-312 and FA86-0015-317
    Basically the three part numbers you mentioned give you the same lock but the different part numbers allow you different options for the key. If you order the part # FA86-0015-312 you get the key number 312, or the part # FA86-0015-317 you get the key number 317, and if you order the part FA86-0015-318 you get key number 318. This is so you can decide if and when you want your locks keyed alike. The part # e98882 can not be keyed to the Fastway locks as it's a different brand and uses...

  • Can a Coupler Lock Be Used with an Equal-I-zer Weight Distribution System
    Coupler lock # FA86-0015-318 is meant for use when the trailer is parked and not coupled to a ball on the tow vehicle. It cannot be used while the trailer is connected whether it is to a regular ball or to a weight distribution system such as the Equal-I-zer system # EQ37100ET. To keep the trailer coupler locked while towing your daughter might be able to use a coupler latch lock but it depends on the coupler.
