This is the best product of its kind that I've found. The 1st one that I purchased 5 years ago served me well until I trailered an entire day before realizing that I had forgotten to lock it in place, leaving it on the tongue of my boat trailer. I particularly like this design because it can be "turned in"/ tightened until flush with the receiver, with no play whatsoever unlike some other designs that simply snap in place like a standard padlock and have sloppy play. I believe that locks are for the most part simply a deterrent to theft, not preventative. This design is attractive, very functional and reasonably priced. Ordered a pair of them for my daughter's family boat as well as my own. 686353



- e98888
by:

This product was sold to me to work with the 2 5/16” ball coupler, that I purchased at the same time. The shaft of this lock is smaller than the hole in the coupler, by a great margin. The lock fit in the coupler is sloppy, and could be cut off easily because of the miss match. Not good. If you order one, make sure the shaft diameter is correct for the coupler you intend to use it on. It probably works Ok on the correct coupler. 686333

Very nice lock for a specific trailer tongue you have. The lock is well built. Just hoping it’ll be bullet proof when it comes to thieves. Other than that I’m happy with the product. 887042

by:

The product is very nice, and the ability to get keyed alike is great! The quality is quite good, and even the dust cover is way better than others I've seen. The people at etrailer were extremely helpful and nice to work with. My only suggestion for the product line would be add another size between 2.5" and 3.375". On two of my trailers, I need a 2.75" lock, but have to go with the 3.375", and it sticks out a lot on both ends. 826184

Quality product and easy to operate. I use it on my dump trailer to lock it to my truck hitch. It works perfectly and gives me assurance that my trailer will stay locked to truck. Thank you etrailer for offering great products at great prices. 815823



- e98888
by:

This is the second product I have purchased in this category. Both are not ideal in my opinion. This product requires the user to unscrew the locking mechanism with the key like you are unscrewing a nut from a bolt (it takes many turns with the key inserted). I was really looking for a simple quarter turn key movement to unlock the device. I would not recommend this product to others. 809194



- e98888

It will suit it needs as it is not the only lock. Probably not very pick resistant. I'm just looking to have would be thief finding easier targets. 797581

Ask the Experts about this etrailer Trailer Coupler Locks

  • Coupler Pin Locks that Can be Keyed Alike
    We have coupler pin lock locks that can be keyed alike like the part # e98888 which has a span of 3-3/8 inches and # e98887 which has a 2-1/2 inch span. Or even # e98890 with a 7/8 inch span or # e98886 which has a 2 inch span. On the product page you'll select keyed alike on the drop down menu and all of the locks will use same key.

  • Coupler Lock Recommendation for a Demco Coupler
    I really wish we had a coupler lock in the dimensions you listed, but the closest thing we offer is the part # e98888 that you referenced that has a 1/4 inch diameter pin that is 3-3/8 inches long. The difference would only be 1/16 of an inch so this lock should still work for you. There's no reason it wouldn't. Another option you have is a coupler lock like the part # DT25013KA. This lock can fit nearly any coupler and should work well for you.

  • Recommended Hitch Pin Lock For UFP A-60 Coupler
    The coupler lock I recommend for your UFP A-60 Coupler is the Coupler Lock, part # e98888. Since the coupler measures 3-inches wide and the pin hole is 1/4 inch diameter the # 28012 will work great to secure the coupler. The lock has a covered key slot to keep dirt and helps prevent corrosion. This is a keyed-alike item so if you want more than one lock and need them all to use the same key you can use the drop-down box on the product page when ordering.

  • Difference Between Keyed Alike and Keyed Unique on DeadBolt Coupler Lock
    When looking at our etrailer.com Coupler Lock # e98888, or any of our etrailer.com locks, "Keyed Unique" means that each of the locks you purchase (if you purchase more than one) will use a different key. If you select "Keyed Alike" instead, each of the locks you purchase (again if purchasing more than one) will use the same key, making it much easier to keep track of if you have multiple trailers. If you are just purchasing one unit then it does not matter which option you choose (although...

  • Recommended Equipment Needed to Lock Boat Trailer to 2013 Ranger Trail
    If you already have a hitch receiver lock then you can use a coupler lock, like our etrailer.com part # e98888 that you referenced, to deter theft of your trailer. However, if you do not already have a hitch receiver lock then I recommend using something like the Bulldog Lifelong Trigger-Style Coupler Lock and 2" Trailer Hitch Receiver Lock # BD580404 instead. This will help to deter someone from simply removing your ball mount to steal your boat trailer. The receiver lock is compatible...

  • Trailer Coupler Lock with Pin Length of At Least 3 Inches
    The closest option we have available to what you are seeking is our etrailer.com Coupler Lock # e98888. This coupler lock does feature a 3-3/8 inch usable span but the pin itself has a 1/4 inch diameter. This diameter is just a tad smaller than what you are looking for but it will still work on your coupler to either lock the trailer to the hitch ball when you're towing or to help deter theft when the trailer's left unattended. I have attached a short video review that you can check...

  • Compatibility of etrailer Coupler Lock on a 2-5/16 Inch Bulldog Coupler
    Good news, I can help you figure out if this coupler lock will fit your Bulldog coupler. As long as your pin diameter on the Bulldog coupler is larger than a 1/4 inch and the span is no bigger than 3-3/8 inches, then this coupler lock will work for you. I pulled the Bulldog coupler # BD028287 you had looked at from our warehouse and a similar style 2-5/16 inch # BD028499 and measured the size of the lock pin that goes in the coupler. It measured 5/16 inch diameter and a length of...

  • Dimensions of etrailer Lock for Surge Brake Trailer Couplers
    The etrailer.com Lock for Surge Brake Trailer Couplers, part # e98888, should work for your trailer hitch. This product has a center span of 3-3/8 inches and a pin diameter of 1/4-inch. The center span is the space between the two black end pieces. Since you need 3 inches of pin length this part should work just fine as it provides 3-3/8 inches. It has an overall tip-to-tip length of 6-3/4 inches. This part is available in keyed-alike multiples if required.

    Locks are for keeping honest folks honest, just about any lock can eventually be defeated if the crook is determined enough. The lock you mention, part # e98888, provides what I would call minimal deterrence against theft. If there are two identical boat trailers parked side by side, one using the # e98888 lock, and the other unlocked, the lock will do its job and deter the crook from taking your trailer. One quick snip with some bolt cutters, and the lock will be defeated, but the...

  • Can etrailer Coupler Lock Be Used to Lock 5th Wheel Hitch to Bed Rails
    The etrailer.com Coupler Lock # e98888 that you referenced is intended for locking the top latch on a hydraulic actuator. We do offer locks like the Tow Ready # TR63254 that are intended specifically for 5th wheel applications. However, the center span of # e98888 is 3-3/8-inches, which is long enough for a 5th wheel application as long as you have enough clearance for both ends of the lock. Note that the 1/4-inch pin diameter is smaller than the 1/2-inch hole diameter on your hitch...

  • Locking Options for Brake Actuator
    You can use the Trailer Coupler Lock for Surge Brake with 3-3/8" Span, part # e98888, to lock a actuator like # T43397007K once it's attached to the hitch ball through the latching mechanism on the top of your coupler. This product has a wide width so it will clear the sides. The Master Lock 1-7/8" and 2" Trailer Coupler Lock, part # 377DAT, is an option that locks the trailer when it's not connected to the hitch ball. It attaches where the trailer hitch ball would go.

    I am not sure what application you are using the detent pin for. Typically they are used on something like an umbrella or can be found on some bike or ski racks. We do not offer locking detent pins but we do have locking pins that may work well for you. One lock I recommend is part # e98888. This is a 1/4 double chrome finish and has a protective cap on the locking porting to keep dirt and moisture out. The pin on this lock is 3-3/8 inches long. For a lock that has a 2 inch span...

    Since you would need a larger deadbolt style coupler lock than we offer I recommend you get a Fastway Universal Trailer Coupler Lock # DT25013KA.

The Coupler Lock # # e98888 that you referenced is the longest deadbolt style at 3-3/8 inches that we offer.

    I have a couple of options that would work for you. If the trailer is sitting around not coupled to anything, and you're wanting to prevent an unauthorized person from coupling it and driving off, use # e98894. If you're wanting to prevent the trailer from being uncoupled from a hitch, use # e98888. This lock will also prevent the trailer from being coupled, but I find the # e98894 to be more secure. The # e98888 would be inserted through the transverse hole just below the latch, as...

    For your Demco Channel Tongue Trailer Coupler part # DM13203-52 I recommend using the etrailer Surge Brake Coupler Lock part # e98888. This is designed to place through the coupler pin hole just under the latch and keep it from being able to operate. This will prevent it from opening or closing eliminating any issues. If you want complete coupler coverage the etrailer Trailer Coupler Lock for Flat Lip 2-5/16" Ball Coupler part # e98895 is an excellent choice. They are both very...

  • Coupler that's Easier to Lock than Bulldog Collar-Lok
    You are correct, all someone would need to do is cut the metal rods you pointed out to be able to slide the sleeve back of the coupler. Because of that you might be more interested in a Demco Coupler # DM13203-95 which uses a much more concealed latch and lock mechanism that wouldn't be as easy to defeat. For a pin lock for the Demco the part # e98888 would work really well too.

The only way I am aware that the trailer coupler can be locked is with a pin style lock like part # e98888 which can be keyed alike if you have other trailers or a wraparound style lock like part # DT25013KA which can also be keyed alike if you have other trailers.
