With the slanted side of the lock pointed toward the front of the coupler, simply place the coupler lock's raised ball up under the coupler and into the coupler's ball hole. The sides of the lock will surround the coupler. 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. Then secure the pin in place with a padlock (sold separately).

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!

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.

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.

Still great - practical, worthwhile product

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.

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.

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.

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

This trailer coupler lock is great. Heavy duty and allows me to use my own lock. You can position the pin to best fit your trailer coupler. Etrailer is great. They followed-up with a phone call after I placed my order, kept me informed of shipping information and followed up again with an email after the product arrived. I will continue to use etrailer for the excellent customer service which is very hard to find these days. They know what they sell and the product reviews are extremely helpful.

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!

I have three different trailers and this lock will work on all of them. I did find the same item for a bit less at national tool store chain, but adding this item gave me free shipping on my entire order so I came out way ahead. Product videos are fantastic! I have never seen another website that takes the time and effort to give you a product video to assist you with your purchase. Hats off to etrailer for their excellent customer service!

These locks worked perfect for our company. Works great in an environment that has several drivers using rotating trailers and rigs. Once we purchased several keyed alike locks we were able to avoid down time from chasing keys and locks around.

Use this on my camper trailer. I like the fact that I can use a separate lock so that I can lock the propane tank and the battery to this device also.

Ask the Experts about this Blaylock Industries Trailer Coupler Locks

  • 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...

  • 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 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.

  • 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.

  • 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...

  • 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 # DT25013KA which allows for many adjustment points for a precise...

    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...

  • 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.

  • 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.

  • 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. You can use the "keyed alike" drop down option if you're purchasing multiple padlocks for additional applications.
