Fight back against trailer thieves with this rugged, rustproof aluminum trailer coupler lock. Simple yet effective, it prevents removal of the inner tube of your gooseneck coupler to help deter towaway trailer theft. Includes stainless steel padlock.


Features:

  • Coupler lock helps deter theft of your gooseneck trailer that has an adjustable coupler
  • Heavy-duty bracket secures around coupler's set screw to prevent removal of inner tube from outer tube
  • Steel pin slides through bracket and under screw
  • Stainless steel padlock with hardened steel shackle secures pin in place
  • Aircraft-grade, lightweight aluminum construction is strong and resists wear and corrosion
  • 2 Keys are included
  • Made in the USA


Specs:

  • Application: set screws on most adjustable gooseneck couplers
  • Overall dimensions: 4" long x 4" wide x 5" tall
  • Pin diameter: 3/4"
  • Weight: 1-1/5 lbs


After it has been secured, this Blaylock EZ Lock ensures that the inner tube can't be removed from the outer tube of your adjustable gooseneck coupler. Simply position the lock around the set bolt, insert the 3/4" diameter steel pin through the bracket and under the bolt, and secure the pin in place with the included Master Lock padlock.


An additional coupler lock (BLTL-50-40D or BLTL-55-40D - sold separately) is available to prevent unauthorized access to the coupler latch.

  • Lock For Gooseneck Coupler With Cable Release & Lever
    Hi Evon, Appreciate the photo, thank you, and while there is a lock option, the part number you mentioned won't work on your gooseneck coupler with the handle. There isn't a similar type of lock for the bottom of the coupler, the best have is a lock for the set screw, the Blaylock EZ Lock for Set Screw on Gooseneck Coupler # BLTL-51-40D.

  • Recommended Blaylock Gooseneck Coupler Lock
    Thank you for the photo of your coupler. When choosing a lock for the coupler it makes it much easier if you are able to identify the coupler manufacturer. The Blaylock EZ Lock Gooseneck Coupler Lock, part # BLTL-55-40D is designed to fit RAM Gooseneck Couplers. This lock has a wider bracket for the RAM Coupler. If you have a Bulldog, Stallion, Superior, or T.E.M. Gooseneck Coupler the correct lock for you is part # BLTL-50-40D. This lock has a narrower bracket feature. My contact...

  • Lock Compatible With Ranch Hitch Gooseneck Coupler Adapter
    The Ranch Hitch Universal 5th-Wheel-to-Gooseneck Coupler Adapter # AM3100 does not have an integrated lock. You can always add components like the Safety Chains for Ranch Hitch 5th-Wheel-to-Gooseneck Coupler Adapter # AM3109 and the Blaylock EZ Lock for Set Screw on Gooseneck Coupler - Aluminum # BLTL-51-40D. You may be interested in the Slide Hammer for Ranch Hitch 5th-Wheel-to-Gooseneck Coupler Adapter # AM3103 to assist with installation of this product.

  • What is the Width of the Bulldog Gooseneck-to-5th-Wheel Trailer Coupler Adapter # BD0289650300
    The inside width of the Bulldog Gooseneck-to-5th-Wheel Trailer Coupler Adapter # BD0289650300 is 3-7/16" while the outside width is 4". If the inside width of your outer tube is about 3-1/2" then this coupler adapter won't fit. All of our other square inner tubes have the same 4" outer diameter. You may need to swap out your whole coupler for an option like part # BD0289590300 which is the whole adapter; inside and outside tubes. You can lock the king pin with part # e98896 and the inner...

  • Recommended Gooseneck Coupler Lock for Puma Trailer
    We have a few different options depending on the gooseneck coupler you have on your Puma trailer. If you have a Bulldog, Stallion, Superior, or T.E.M. coupler then I recommend the Blaylock EZ Lock Gooseneck Coupler Lock # BLTL-50-40D. If you have a RAM coupler then you would need the # BLTL-55-40D instead. Both of these have an option to come with the Blaylock EZ Lock for Set Screw on Gooseneck Coupler - Aluminum # BLTL-51-40D. You would need the # BLTL-53-40D2 or # BLTL-57-40D2. The...
