  • Fits 2-5/16 Inch Ball
  • Blaylock Industries
  • Surround Lock
  • Keyed Unique
  • Universal Application Lock
  • Aluminum

Sturdy, rustproof aluminum lock discourages towaway trailer theft by fully enclosing your Bulldog Collar-Lok coupler that fits 2-5/16" hitch balls. Can be keyed alike to match other Blaylock push-button locks.


Features:

  • Coupler lock deters theft of your trailer with a Bulldog Collar-Lok-style coupler
  • Heavy-duty shell fully encloses the coupler
  • Steel pin slides up into hitch ball opening to prevent removal of lock
  • Push-button lock secures unit to trailer coupler
    • Located on front of unit for easy access
    • Recessed tumbler provides extra security measure
  • Aircraft-grade, lightweight aluminum construction is strong and resists wear and corrosion
  • Lock can be keyed alike to match other Blaylock push-button locks
    • To order keyed alike locks, select "Keyed Alike" from drop-down menu above and enter the number of locks in Quantity box
  • 2 Keys are included
  • Made in the USA


Specs:

  • Application: 2-5/16" Bulldog Collar-Lok-style couplers
  • Overall dimensions: 4" long x 4" wide x 5" tall
  • Pin diameter: 5/8"
  • Weight: 2 lbs


Notes:

  • Lock can be keyed alike to match other Blaylock push-button locks.
  • To order keyed alike locks, select "Keyed Alike" from drop-down menu above and enter the number of locks in Quantity box.

After it has been secured in place, the Blaylock total-encasement lock renders your trailer's 2-5/16" Bulldog Collar-Lok-style coupler inoperable, ensuring peace of mind. Simply slide the lock over your coupler, push the 5/8" diameter pin into the coupler's hitch ball recess, and push in the lock mechanism. Your coupler is now completely surrounded. The sturdy steel pin extends to the top of the recess, and the pin cannot be accessed while the unit is locked.

Looks like a great product, but it does not fit my hitches on my trailers. My trailers have the extra flange around the ball area and this will not fit. I really like the lock though and might use it for something else.

Barely fit on the hitch but I lubbed it up and managed. It works well for me because the rv is stationary. Wouldn’t work for someone needing to get it on and off often. Made in the USA ??

Did not fit over my bulldog coupler. etrailer.com was of course good about a prompt RMA.

Ask the Experts about this Blaylock Industries Trailer Coupler Locks

  • Alternative to Blaylock Total-Encasement Coupler Lock that Fits Standard Lipped Couplers
    Thank you for sending the photo! While I have a solution for you, the Blaylock Total-Encasement Coupler Lock, part # BLTL-23 will not work. I is designed to fit Bulldog Collar-Lok style couplers that use a 2-5/16" ball, like # BD028463 for example. For a lipped coupler, like yours, Blaylock does offer the EZ Lock Trailer Coupler Lock for 2-5/16" Lipped Couplers - Aluminum - Push Button # BLTL-34. Or, if you prefer something that provides a more complete enclosure for your coupler,...

  • Coupler Lock for 2-5/16" Trailer Coupler Ball
    We do not have any type of database of parts lists on each year, make and model of trailer so while we cannot tell you what type of coupler you have on your 2005 Airstream there are universal applications that should work. I recommend checking out the Master Lock Trailer Coupler Lock # ML389DAT which will work on your Airstream if you have a standard lip, rolled lip, straight lip, surge brake, hammer blow or UFP couplers. If you take a look at the accompanying photo you can see how...

  • Recommended Lock for Demco DM14040-81 Coupler
    The # BLTL-23 Blaylock coupler lock is compatible with a very specific type of coupler, the CollarLok like our part # BD028499, so it wouldn't be a good fit for a coupler like the Demco # DM14040-81. A lock like the # DT25013KA or a latch type lock such as # 2847DAT would be your best fits.

  • Inside Width of Blaylock Total Encasement Coupler Lock # BLTL-23
    The inside width of the Blaylock # BLTL-23 is 3-1/4 inches, as you can see in the photograph I've edited for you. I don't know which website you're referring to, but the information is incorrect.

  • Securing Steel Coupler To Aluminum Car Hauler Trailer Tongue To Prevent Theft
    Thanks for the photo of your trailer coupler. That really helps explain what you are asking about. I spoke with a couple of other Experts and we may have a couple options you can consider. One way to go is to use Loctite Threadlocker 262, part # LT37420 on the coupler bolt threads. This is put on the threads when bolting the coupler to the trailer tongue and becomes impossible to remove with hand tools without heating it up to 500F degrees to free the parts for disassembling. That would...

  • Recommended Trailer Coupler & Wheel Locks
    The best type of lock for your Bulldog adjustable 2-5/16-inch trailer coupler depends on the coupler design. If you have a Bulldog Collar-Lok Coupler like # BD028585 then I would go for the Blaylock Total-Encasement Coupler Lock # BLTL-23 over the Fastway # DT25013KA simply because it fully surrounds the coupler. Deterrent value is high! If you have other trailers to lock then in that case the flexibility of the Fastway could make it your better option. For just this one trailer, go for...

  • Coupler Lock that Fits EZ Latch Demco Coupler without Lip
    For the channel style of Demco EZ latch coupler that does not have a lip around it you'd want the wrap around style coupler lock like the part # DT25013KA as the # BLTL-23 only fits the Bulldog Collar Lok style couplers.

  • Lock Recommendations for a Collar-Lok Style Trailer Coupler
    It sounds like you have a Collar-Lok coupler such as # BD028244. For that type of coupler you could use lock # BLTL-23. The body is aluminum but the pin inside that goes way up into the coupler is steel. It fits 2-5/16 inch Collar-Lok couplers. For 2 inch models use # BLTL-22. Another option, if your coupler has the pin behind the collar to keep the collar from sliding back, is to use a lock such as # e98888 in place of the pin. This would prevent the collar from opening all the way....

  • Locks for 2-5/16-Inch Coupler on Travel Trailer
    We offer many styles of locks for 2-5/16-inch trailer couplers and all of them are shown on the linked page. All are the surround type lock and we have some that fit all coupler sizes, such as the Fastway Universal Trailer Coupler Lock # DT25013KA. For a lock specific to a 2-5/16-inch coupler that completely encases the coupler you might consider the Blaylock # BLTL-23.

  • Recommendation for a Coupler Lock for a Collar-Loc Trailer Coupler
    Master Lock coupler lock # 3784DAT is not the best option for a Collar-Lok coupler. For a Collar-Lok coupler I recommend a lock designed for then such as # BLTL-23 (2-5/16 inch ball), # BLTL-20-40D (1-7/8 to 2-5/16 inch balls), or # BLTL-22 (2 inch ball).
