The products sold by E Trailer is always the best and I have dealt with George for years and appreciate the fact that they look after the customers and NOT out just to make a buck, quality ownership of anything they sell.

Appears that it will do the job. It's not very complicated, clamps on hitch to make trailer stay where you park it.

This theft deterrent works just fine, super easy to use WHICH MEANS YOU SHOULD USE IT !!! Any theft system is really to stop the person that is not fully prepared to steal something. So using this is 80% of the solution to having your trailer borrowed permanently. Easy to put on and you have to use the disk style lock as this is the only lock that can't be cut into by bolt cutters. Do not use a cheap pad lock or the thieves will go at the WEAK part of the system.

Still have my trailer and wheels. Thank you for checking in.

love these. fit many trailer balls & I can use my own locks. Hole is a bit narrow for standard "Discus" locks, but 10 sec with a burr on the drill fixes that.

This is the best lock for a Bulldog Style hitch i have seen. We used this lock to integrate into our Master Lock Keyed Alike System. No more hunting up the missing key; time and money saver at work and at home. Thanks

Good product but not usable on my hitch which is compound locking. Good only for the standard lever lock hitch.

The lock part BLTL-20 is designed for bulldog collar-lok couplers. If you have a traditional style latch lock on your coupler I recommend part # DT25013KA
Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers
$46.20 fastway universal trailer lock. Please keep in mind, the maximum coupler width must not exceed 4-3/4 inches to use DT25013KA.

I bought this for my rv trailer. I have a two inch ball. It fits a little snug but serves the purpose. It needed to be about a half inch wider to sit squarely for my trailer.

works only for very specific hitches with very very narrow flange around the ball area. make sure the dimensions work for you. Mine sit on the shelf unused

Make sure you have the Buldog hitch it will not work with wider ones with the flanges on them

Big ol hunky piece of aluminum with a steel pin that does what it is to do, make it very difficult to steel your trailer when it is not attached to the vehicle.

Looks like good quality piece, just too small to fit my 2 5/16” tongue. The uprights that hold the pin will not fit around the tongue. I should’ve done my homework and ordered the TL 33.
Comments
The locking shroud has an inside width of 3-3/16 inches, so in order to fit your coupler would need to be narrower than that.

the blaylock bulldog style receiver lock is just what I had hoped.they say it is made from hd aircraft aluminum and I have no cause to doubt that.the lock rod is hardened steel.although it has not been tested(theft attempt)it does give me peace of mind when I leave home. it seems to be a fine u s made lock and fits good,is easy to put on and remove.i'm happy with it.

Excellent product, fast shipping and built to handle! This is no cheap plastic trailer tongue lock, very heavy duty and will accept any standard lock, which I needed to interchange lock keys on occasion. Highly recommended and etrailer is the only place I could find this type of lock.

The trailer lock doesn't fit my trailer.
Comments
The inside width of this coupler lock is 3-316 inches, so it will not fit couplers that are wider than that.

The coupler lock is a great idea! Easy to use, and made from light weight cast aluminum. The lock pin will accept any standard sized padlock. I like that the lock pin also covers hitch latch, to prevent tampering. Pros: Light weight, small, simple, good finish, easy to use, cast aluminum wont rust or corrode. Cons: Cast aluminum, could be quickly cut through with hacksaw. Locks only keep the honest people from stealing your stuff, but its better than not having any lock.

- Could Lock with 7/16 inch Diameter Pin Fit EZ Lock Trailer Coupler Lock BLTL-20It might be a little bit tight but a lock with a pin diameter of 7/16 inch would fit the EZ Lock Trailer Coupler Lock # BLTL-20 that you referenced.
view full answer... - BLTL-20 Coupler Lock Fit a Bulldog Coupler Heavy-Duty Cast Head Coupler w/ Wedge LatchI went and pulled a coupler like you have part # BD44150W0317 and the coupler lock you are interested in part # BLTL-20 and found that they lock is wide enough to fit this coupler. I attached a picture that shows the two products next to each other to show that they would fit.

- What Type of Coupler Does BlayLock Coupler BLTL-20 FitThe Blaylock Coupler Lock # BLTL-20 that you referenced is designed to fit the Bulldog Collar Lok style couplers like what you see in the picture I attached. If you are looking for a more universal style lock the Fastway part # DT25013KA is very universal and effective. It also works on Collar Lok couplers as well. The second picture I attached shows this lock installed on a few of the more popular coupler designs.

- Inside Width of Blaylock Industries EZ Lock Trailer Coupler Lock # BLTL-20The EZ Lock Trailer Coupler Lock # BLTL-20 referenced in your question has an inside width of 3-3/16 inches. The overall dimensions on the unit are 2-1/2 inches long, 4-1/2 inches wide, and 5 inches tall. This is a really nice coupler lock that will help deter theft of your trailer. The heavy-duty brackets fit around the trailer's coupler and the raised ball on the platform sits inside the coupler. A steel pin slides through the bracket to secure the lock to your coupler.

- Could Bolt Cutters Cut Through Pin of Blaylock Coupler Lock # BLTL-20The pin of the Blaylock Coupler Lock # BLTL-20 is 3/4 inch diameter steel. It would be difficult but somewhat possible for a set of bolt cutters to make it through.
view full answer... - Padlock Size and Recommendation for Use with EZ Lock Trailer Coupler Lock # BLTL-20For a lock for the EZ Lock Trailer Coupler Lock # BLTL-20 we actually recommend disc-style padlock # ML40D both of which have a 3/8 inch diameter shackle. I have linked a video review of the EZ Lock coupler lock and in it our video team shows this style lock being used.

Instead I recommend the Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers # DT25013KA which is the same concept but is adjustable and will work perfectly on your # DM69FR.

This coupler is 3-3/16 inches wide and 4 inches tall. It is roughly 2-5/8 inches tall to the bottom of the 3/4 inch pin. If you want this with the padlock, then use # BLTL-20-40D instead.

- Recommended Coupler Lock and Padlock Compatible with Standard Travel Trailer CouplersThe EZ Lock Trailer Coupler Lock for 1-7/8", 2", 2-5/16" Bulldog Collar-Lok Couplers # BLTL-20 is specifically designed for a collar lock style coupler like # BD028657. For a standard travel trailer, you most likely do not have that style coupler, so I recommend the Blaylock EZ Lock Trailer Coupler Lock for 1-7/8", 2", and 2-5/16" Couplers - Aluminum # BLTL-33 for the same style that is compatible with most travel trailer coupler styles. If you want one with a padlock included, I recommend...
view full answer... - Inner Width of Blaylock Coupler Lock # BLTL-20The inside width of the # BLTL-20 that you referenced is 3-3/16 inches like what you can see in the attached picture. Based on that it would be 1/16 of an inch too narrow to fit your coupler. The Fastway Lock part # DT25013KA might be a better option for you to consider. This lock is our best selling coupler lock because of how well it works and how easily it fits most coupler sizes and styles.

- Keyed-Alike Trailer Coupler LocksWE have many coupler locks that can be ordered wit the same lock core so that one key will work on all of them. You can see all such items on the linked page, such as Fastway Universal Trailer Coupler Lock # DT25013KA. This fits 1-7/8-inch, 2-inch and 2-5/16-inch couplers. Once you choose your preferred lock just select the Keyed Alike option which is above the yellow Add to Cart button. There is a small upcharge for this keyed-alike option.

These locks include types like the EZ Lock Trailer Coupler Lock # BLTL-20 which works along with a pad lock that you supply, such as # ML40D. We do not offer any lock products intended to secure a hitch ball to a ball mount. Usually hitch balls will be torqued (according to the manufacturer's instructions) to a degree that would make it hard to unscrew the nut that holds the...
view full answer... - Material Components of the EZ Lock Trailer Coupler LockTHe lock body of the EZ Lock Trailer Coupler Lock, part # BLTL-20 is made from aircraft grade aluminum. To actually lock the coupler lock, you'll need to purchase a 3/4 inch diameter locking padlock like part # ML40D.
view full answer... - Recommended Coupler Lock For Surge Brake Actuator On Continental Boat TrailerI may have another option for you, but the EZ Lock Trailer Coupler Lock # BLTL-20 you were looking at is only confirmed to fit the Bulldog Collar-Lok Couplers so it will likely not work on your surge brake actuator. I looked up your Continental Model A2485B-8500 trailer and to lock the surge brake actuator you will need the etrailer Surge Brake Coupler Lock # e98888. I included a video of the # e98888 for you to take a look at.
view full answer... - Coupler Lock for Demco Trailer Coupler DM14976-52The most similar coupler lock we have to the # BLTL-20 that would fit the Demco coupler # DM14976-52 would be the Fastway part # FA86-0015-316 which fits into the coupler and has a bar that runs across the top of it but since it has a little more universal of a design it can fit the Demco.
