Features to know about

Versatile Drop-In Solution: Universal Compatibility with Multiple Couplers

If you’ve got multiple trailers with different coupler styles, the Blaylock EZ Lock is your new best friend. It’s designed to fit most 1-7/8", 2", and 2-5/16" hitch balls, and works seamlessly with trigger-style, latch-style, and handwheel-style couplers. Forget the hassle of buying multiple locks—this one’s a universal fit, perfect for anyone who handles a variety of trailers.

Rustproof and Resilient: Aluminum Construction

Trailer locks take a beating from the elements, but the Blaylock EZ Lock stands strong. Made from aircraft-grade aluminum, this lock resists wear and corrosion like a champ while remaining lightweight. It's a stellar choice for long-term reliability and no-rust performance, making it ideal for outdoor storage and tow ventures in rugged environments.

Extra Security for Peace of Mind: 3/4-Inch Pin Design

Secure your trailer with confidence using the solid 3/4-inch steel pin that slides through the bracket and locks your coupler in place. It offers a robust defense against potential thieves, ensuring that your valuable asset stays put. Pair it with your own padlock for an extra layer of security to keep unwanted hands off your trailer.

Designed for Durability: Built to Withstand Theft Attempts

In a world where security can’t be taken lightly, this lock offers a heavy-duty bracket that envelops your trailer’s coupler, making it a formidable barrier to thieves. It’s not just a lock; it’s a visual deterrent that warns would-be criminals to think twice. When secured with a sturdy padlock, it’s a clear "not today" message to anyone considering making off with your trailer.

Adaptable Fit: Multiple Pin Hole Positions

Achieving a snug fit on your coupler has never been easier. This lock comes with three pin hole positions, allowing you to customize the fit to your specific coupler. Whether you’re securing a small utility trailer or a beefy travel trailer, you can select the position that holds snugly, minimizing any rattle or wobble for a secure hold.

Simplified User Experience: No Padlock Restrictions

Say goodbye to proprietary locks and hello to flexibility. The Blaylock EZ Lock isn't just secure—it’s convenient. You can use your own padlock, allowing for a custom key setup that integrates seamlessly with your security needs across different trailers. It's designed for ease, adaptability, and personalized security, making it a smart addition to your trailer security lineup.

I read the reviews and it is exactly as I expected. However, I was surprised that the reviews also said the follow up from the company was excellent. I didn't believe it, but now I do. Great company to work with. Thanks!!!!!

Love this product!

As previously mentioned in another review, the casting of BLTL-33 has numerous places where grinding was done during the manufacturing process. Definitely not the level of quality that I was expecting.

It looks well built but it didn't fit my camper

  • Coupler Lock Recommendation For Dexter DX7 Coupler
    Hello Bob, thanks for reaching out. We have a few option for locks that will fit the Dexter DX7 coupler. For a locking pin I recommend the etrailer Surge Brake Coupler Lock # e98888. This will allow you to lock the coupler to the ball. The picture below shows it installed on a similar Dexter surge brake coupler. If you are looking for a lock for while the trailer is in storage, I recommend the Blaylock EZ Lock Trailer Coupler Lock # BLTL-33. We have confirmed that this will fit on the...

  • Will Blaylock EZ Lock Trailer Coupler Lock fit UFP Square Bodied Coupler
    If the front part of your square-bodied coupler is approximately 3 inches tall, based on the inner dimensions of the lock the Blaylock EZ Lock Trailer Coupler Lock # BLTL-33 will work well for you. The # BLTL-33 has inner dimensions of 3-1/8 inches x 4-3/4 inches, when the bar is installed in the tallest position. Another factor to consider is the location of your coupler latch. The key is securing the lock in the underside of the coupler while also covering the latch on top of the coupler...

  • Coupler Lock for a UFP A-60 Boat Trailer Actuating Coupler
    From what I was able to find in the research I did, the recommended lock for a UFP A-60 coupler is a simple pin design, # e98888. This should prevent the handle from operating while the lock is in place (basically used in place of the pin. The difference is that this pin includes a lock). In my research I found that locks like # BLTL-33 are not considered a fit.

  • Difference Between Blaylock TL-20 and TL-33 Coupler Locks
    Sure thing! The EZ Lock Trailer Coupler Lock # BLTL-20 is for Bulldog Collar-Lok-style couplers while the EZ Lock Trailer Coupler Lock # BLTL-33 is designed for Fulton, Shelby, Dutton-Lainson, Atwood, and similar couplers. I've attached some review videos for you to check out.

  • Recommended Trailer Coupler Lock for a 2-5/16
    I want to start off by saying that any trailer lock that you purchase will never be able to fully secure your trailer from a thief. If they are determined enough to bring equipment with them to remove a lock then given enough time they will be able to remove a lock. This will be the case no matter what you what you are looking to put a lock on. With that being said, the Blaylock EZ Lock Trailer Coupler Lock # BLTL-33 that you referenced is a great lock that has received many great reviews...

  • Can Puck Lock Be Used with Blaylock EZ Lock Trailer Coupler Lock # BLTL-33
    The Blaylock EZ Lock Trailer Coupler Lock # BLTL-33 is designed to work perfectly with a standard padlock, but I think the typical opening size on the back of a puck lock will be a bit too small to fit over the end of its pin/shank. The pin/shank on this lock has a 3/4" diameter, while for example the opening on the Master Lock Puck Lock # ML6271 we have available has a height of just 19/32", which wouldn't allow it to mount over the pin. Your best option is going to be with something...

  • Will The Blaylock EZ Coupler Lock Work With A Demco EZ Latch Coupler.
    I have a solution for you. The Blaylock EZ Lock Trailer Coupler Lock for 1-7/8", 2", and 2-5/16" Couplers - Aluminum # BLTL-33 will not work with the Demco Trailer Coupler - Cast - Adjustable Channel - eZ-Latch - Black - 2-5/16" Ball - 21K # DM14040-81. You will need a coupler lock like etrailer Surge Brake Coupler Lock - 3-3/8" Span - 1/4" Diameter - Chrome # e98888. This can be used while coupled to a trailer or while off vehicle.

  • Replacement Clevis Pin Recommendation for a Blaylock EZ Lock Trailer Coupler Lock

  • Can Blaylock EZ Lock Trailer Coupler Lock Fit Demco Channel Style Coupler # DM13203-95
    Yes, the Blaylock EZ Lock Trailer Coupler Lock # BLTL-33 that you referenced does fit the Demco Channel Tongue Trailer Coupler # DM13203-95 that you referenced. The max diameter shackle you could fit through the hole on the 3/4 inch long pin is 3/8 of an inch like what the Master Lock Stainless Steel Padlock # ML40D has.

  • 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...

  • Locks for Hasps and 2-5/16" Coupler With Trigger Latch
    We don't have an option that will allow for all of them to be keyed alike but I can get you down to one key for the hasp locks and another for the coupler lock. The Trimax Puck Locks for Trailer Door Hasps # TMX73FR comes with three keyed-alike locks with a 3/8" shackle. The shackle is hidden so there it can't be cut by a thief. These have a steel construction and chrome finish. The locks could then be paired with the Blaylock EZ Lock # BLTL-33 or Trailer Coupler Lock - Butterfly Style...

  • Inner Dimensions of the Blaylock EZ Lock Coupler Lock # BLTL-33
    I pulled the Blaylock EZ Lock Coupler Lock, # BLTL-33, from our warehouse and took some measurements for you. The inside width of this coupler lock is 4-3/4 inches. From the base to the bottom of the pin, it measures 3-1/8 inches (see photo). If you do not have a padlock yet, I recommend looking at the Blaylock EZ Lock Coupler Lock with Padlock, # BLTL-33-40D. This is the same coupler lock, but it includes a stainless steel padlock. You could also just purchase the lock separately as...

    The Tow Smart # 3481213 is manufactured in China. If you're looking for a similar lock that's manufactured here in the US, I'd recommend theBlaylock # BLTL-33. For a compatible padlock, I'd recommend the # ML40D from Master Lock. I've linked to a product demonstration video featuring the Blalock EZ Lock Coupler Lock.

    The 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...

  • Does the Blaylock EZ Lock Trailer Coupler Lock # BLTL-33 being Made of Aluminum Still Deter Theft
    While aluminum is a softer metal than steel it still would be difficult enough to cut through, making the Blaylock EZ Lock Trailer Coupler Lock # BLTL-33 an effective theft deterrent. If a thief came across your setup and was willing to cut through an aluminum lock he probably would not be any more deterred if the if he saw that the lock was made out of steel.

Other than our etrailer.com locks like the # e98890 that pass through the latch, I found three locks that would work pretty well for you. The fit of the Blaylock EZ Lock # BLTL-33 was a bit loose, but once the locking bar was slid into place, I was unable to remove the lock by hand, although a pry bar might get it off.

  • Maximum Padlock Shackle Diameter to Fit Blaylock EZ Lock Coupler Lock BLTL-33
    The Blaylock EZ Lock Trailer Coupler Lock # BLTL-33 can be used with a padlock shank that is no thicker than 3/8 of an inch so your padlock with a 14 mm (0.55 inches) shank is too big to fit through the hole on the pin. We do have the Master Lock Stainless Steel Padlock # ML40D which has that 3/8 of an inch diameter shank and is a very popular option to pair up with the BLTL-33.
