Slide the 3/4" diameter pin through 1 of the 3 pin hole positions on the lock, selecting the position that will hold the lock snugly in place on your coupler.

by:

It broke about 40 days later they wouldn’t replace it due to 30 day warranty. Waste of money made very porely.



by:

the best keeps people away from the trailer that are more than just looking its really a great deterrent to thieves they look else where.



by:

I am very happy with this lock and the way it fits the hitch. I would 100% buy this one again.



by:

Nice and sturdy coupler lock. Works great and the multiple holes for the locking pin provide lots of flexibility.



by:

Work perfect! Strong and weather resistant. Adaptable to several style coupler hitches



by:

Very pleased with the ease of use for this trailer lock. It is the only style that will fit on my square receiver! Light weight yet sturdy! Very fast shipping. (Lock sold separately)



by:

Great, solid locking mechanism! It's no flimsy piece of metal, so if you use a good padlock of some sort (I love Paclock - pretty much unpickable and very hard to force), any thief will need some serious tools to hack / cut through this piece of hardware. Very simple - fits great on my two inch coupler. Definitely a good investment to protect your equipment!

Still awesome after a year! No corrosion, still slides together without a hitch. And still just a great design - highly recommend!



by:

Was exactly as described on the website. No gimmicks.



by:

Just what I needed for my oversized hit ch.



by:

it works but would have like it supplied with its own lock.



by:

It seems like the affordable option to protect a trailer. It is made of aluminum so it could be cut off, but it would probably be faster to grind through the steel shackle of the padlock that secures it.

I used this hitch protector, a chain to a post, and a chain around a wheel and the frame of my utility trailer with three matching locks from etrailor.

I think that those three deterrents will slow thieves down. Make sure that your trailer coupler is secured to the trailer itself. I spot welded my trailer coupler in place.

There is only so much you can do. This deterrent is effective for its price point.

Still working great after a year. It is a solid deterrent for the price point!



by:

I have used this product for 12 years on trailers to tow bars on SUVs and ordered two more. This is more practical for me because it can take a Combination hasp lock instead of a key like all other coupler locks, which I never seem to have handy. etrailer was very prompt on shipment of all the products I have ordered from them. Good products, excellent service.

Kak

Still great - practical, worthwhile product



by:

I like this coupler because it allows you to use your own pad locks. Comes in real handy when you have more than one trailer to keep secure. Keyed alike padlocks is so much more simple than having to carry around multiple keys for the other type locks.



by:

Really like this product well built and allows us to integrate our Master key Lock system with this trailer lock. We have a Small business and several trailers at home. Finding the right key to the trailer lock was always a problem;now that problem is gone. I am a happy customer!

I have been very happy with my experience with etrailer.com. Great ion, Good Reviews, Good Prices, Good Product info, Great shipping and customer service. Also, a lot of the items are hard to find, its nice to have a one stop shop.



by:

This tongue lock will work good but is rather loose at best when installed. I’ve seen better tongue locks but I wanted one that would accept my keyed alike disc padlocks. So this will work.

Great. Lock keeps my trailer safe



by:

My trailer is stored in an outside site. While nothing is totally theft-proof this product is heavy and seems well made. It fits my large-flanged Jayco coupler. I bought a good weather resistant heavy lock to go with it. Rather than mess with my trailer I think this will encourage someone to move on to easier pickings. I'm very happy with this purchase.

Hector

One year later and I’m still very pleased with this purchase.



by:

This is the only trailer coupler lock I use. It fits all trailers and is extremely secure. I feel safe knowing my trailer will be there when I come back for it.

It’s working so well that I bought another lock



by:

So far no issues. But then again, I haven’t had anyone try to steal my trailer yet. My biggest complaint is how sloppy the fit is. I did some searching and found out a racquetball is the same size as my trailer hitch, so I cut a hole in one and popped it onto the lock. Now I can just insert the the lock into the tongue and latch it for a perfect fit.



by:

I like that it is aluminum, and it fits my trailer. As it is a universal fit it is looser than I would ideally like but works to keep my trailer secure.



by:

As a trailer dealership we were looking for a way that we could add an additional level of security to our inventory with out having to keep track of separate keys for each lock. the Blaylock provided the perfect solution it fit all the different coupler types that we have and with an order of master locks that are keyed alike I only have to keep one extra key on my ring. We will defiantly be purchasing more of them as our inventory expands.



by:

This is a very nice product. It seems better than any of the other hitch locks I've seen out there with the exception of the Proven Industries lock, which is 6 times the cost. My only feedback is I wish they made one that was specifically made for the 2-5/16 ball because the hitch doesn't actually lock down on this since the "ball" is made to fit the smaller hitches as well. It's a good product though. If someone really wants to steal the camper, they're going to steal it. This will deter most thieves.



by:

This is by far the best coupler lock I’ve ever owned. I like it so much I bought 5 of them so my son could lock up all of his trailers.

Richard

I will only buy these trailer locks! They work well on any type trailer with a hitch irregardless of the ball size or shape of the hitch



by:

Order was shipped and delivered in a matter of days. Status of the order was emailed to me through out the time the order was placed to delivery. Very pleased with the items purchased and the customer service.



by:

These trailer locks are fantastic! We have multiple types and sizes of trailer couplers, so we bought the universal lock to ensure it would fit them all. The locks fit every coupler type we own, are easy to install, are well-built, and provide a welcome sense of security. Thanks for a great product!



by:

After looking at dozens of trailer coupler locks I chose the Baylock TL-33 because of its simple, clean design and the ability to use a quality padlock vs the cheap Chinese made locking mechanism installed on most other coupler locks. The Baylock is made in the USA and is a high quality thick aluminum casting that will never rust and thick 3/4 inch steel locking pin. It looks very strong. I know that every coupler lock from every manufacture can be defeated by a thief given enough time and proper tools... but the Baylock is a great deterrent.

  • 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...

    The Blaylock EZ Lock Trailer Coupler Lock # BLTL-20-40D is specifically meant for use with Bulldog Collar-Lok-style couplers such as # BD028381. For your Atwood 2-inch A-frame coupler you can instead use part # BLTL-33 and lock part # ML40D.

    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...

  • 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 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...

  • Coupler Lock Recommendation for a Bulldog Collar Lok Coupler
    The Bulldog couplers are usually the collar-lok style couplers so you would need to go with a different coupler lock than the # BLTL-33 that you referenced. Instead you would wan the part # BLTL-20-40D as it is specifically designed for collar lok Bulldog coupler. I attached a review video for you to check out as well.

  • Tow Smart Trailer Coupler Lock Place of Manufacture
    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.

  • Recommended Coupler Lock and Padlock Compatible with Standard Travel Trailer Couplers
    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...

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.

    I have a solution for you.

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.

  • Recommended Coupler Locks for Bulldog Cast Head Coupler # BDA256C0317
    I pulled one of the Bulldog # BDA256C0317 couplers off the shelf, and tested it with various coupler locks. 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.

  • 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.

  • 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...

  • 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.

  • 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...

    That is correct. If you check out the attached picture of the Master Lock Stainless Steel Padlock # ML40D (3/8" shackle) installed on the Blaylock EZ Lock Trailer Coupler Lock # BLTL-33 you can see that there is no extra space for a larger size shackle.

  • 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.
