I had seen some negative reviews for etrailer and actually hesitated to place an order, but they had exactly what I wanted and their prices were better than anyone else. So I placed an order..... The customer rep was excellent and very helpful. My order arrived in 2 days exactly as I ordered. Great experience.!!! I would certainly buy from them again. 330331

We have several trailers we use to haul equipment to job sites and have to leave them at site over night so these locks are very sturdy which gives us security from theft and was able to get all locks keyed alike so one key works on all trailers which is convenient. 369817

This lock system is simple and weather exposure should not be a hindrance for removal when needed. I would like to see the pin made of hardened steel. May get a machinist to fab one up out of a harder Rockwell rating. Painted it Orange and it contrasts very well to the black trailer frame. This is a visual que for those passing by the county road, that the coupling has 'something' on it. The Master lock appears to be of a higher quality the the same design but sold for storage unit use. It may be made by Master but have no way of knowing. The lock operates very smoothly and the stainless body is perfect for outdoor application. A shout out to Jennifer who has been providing excellent customer service from day one. This means I will use etrailer for future trailer needs, thanks to her. Hope this helps others. 398959

another excellent product and great free fast shipping. I have a lot of different trailers and locks this locking system is very good to lock the tongue of your trailers. 806205

I am very pleased with the tongue lock. I use it on my boat trailer which I often leave in a Marina for several days at a time while the boat is in a slip. I tend to think of it like all deterrents, another layer of security to overcome which will encourage movement towards an unlocked trailer hitch. It works well, seems sturdy and accomplishes the purpose. 796298

  • Coupler Lock Recommendation for Trailer with 4 inch Wide Coupler
    We have a solution that will work great but the part # BLTL-20-40D would not be what you'd need as it is designed to fit a Bulldog Collar Lok couplare and is only 3-3/16 inches wide. The # DT25013KA would instead be what I recommend as this fits all standard coupler sizes like what you have.

  • Coupler Lock Recommendations for a RAM Brand Trailer
    If your RAM brand trailer has a collar-lock style coupler like the Bulldog Coupler # BD028444 yes the EZ Lock Trailer Coupler Lock # BLTL-20-40D would be an excellent choice as a trailer lock. A more universal coupler lock that we offer is the Fastway Coupler Lock part # DT25013KA. I attached review videos for both coupler locks for you to check out.

  • Coupler Lock that Will Fit 34 1995 Airstream Excella 1000 Travel Trailer
    If your 1995 Airstream Excella 1000 Travel Trailer has a Bulldog Collar Lok style of coupler on it then yes, the EZ Lock Trailer Coupler Lock # BLTL-20-40D would fit and work well. I pulled up pictures of your trailer and wasn't able to verify that this was the style of coupler that the trailer had, but it's also very common for trailers to have the couplers swapped so you may have a Collar Lok style coupler like what I attached a picture of. If you have a different style of coupler...

    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.

  • Recommended Coupler Lock For Best Theft Deterring
    I'm sorry you don't find the Reese Tow and Store Lock Kit # RP7014700 to be acceptable. Based on your description it sounds like you are focused on the coupler lock and we have very positive reviews on this product. However we do offer a wide range of each product to allow you to determine the best fit for your needs and budget. I have linked the page to all of the options to assist. I personally like the Fastway Universal Trailer Coupler Lock # DT25013KA and that is my recommendation...

  • Trailer Coupler Lock Compatible with Wide Coupler
    If you have a Bulldog Collar-Lok Coupler, then the EZ Lock Trailer Coupler Lock for 1-7/8", 2", 2-5/16" Bulldog Collar-Lok Couplers # BLTL-20-40D is your best option. If you want the pin style coupler lock, then the Bulldog Easy Access Coupler Lock - Swivel Head - Chrome # BD580409 is the largest span option at 3-5/8 inches.

  • Recommended Collar Style Trailer Coupler Lock
    The EZ Lock Trailer Coupler Lock for 1-7/8", 2", 2-5/16" Bulldog Collar-Lok Couplers # BLTL-20 is what I recommend for your style coupler as long as it fits the dimensions. 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.

  • Recommendation for a Coupler Lock for a Collar-Loc Trailer Coupler
    Master Lock coupler lock # 3784DAT is not the best option for a Collar-Lok coupler. For a Collar-Lok coupler I recommend a lock designed for then such as # BLTL-23 (2-5/16 inch ball), # BLTL-20-40D (1-7/8 to 2-5/16 inch balls), or # BLTL-22 (2 inch ball).

  • 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.
