Video Transcript for Tow Ready Gorilla Guard Trailer Coupler Lock Review

Today we're going to be taking a look at the Tow Ready Grill and Guard Coupler Lock. We've got two sizes available. The 2" is part number 63228; the 2-5/16" is part number 63227. These trailer coupler locks are great for securing your unattended trailer, preventing anybody from being able to hook up to them. They offer a gorilla guard design, which as you can see is a nice, heavy-duty lip, with structural supports all the way around our lock to prevent any kind of tampering. It has a single action, cylinder style key. Push in, a quarter turn out.

Key is removable. To attach it to your trailer we simply bring it onto our coupler, push up on the lock. As you can see that's all there is to it. Our trailer is secure, we can leave it for a while and don't have to worry about anybody hooking up to it and it getting taken from us. Now that we've gone over the details and you've seen how it works, that will complete today's look at the Tow Ready Gorilla Guard Coupler Locks, part number 63228 in 2" and part number 63227 in 2-5/16". .

Trailer Coupler Lock - Gorilla Guard for 2-5/16" Couplers - 63227

Average Customer Rating:  4.2 out of 5 stars   (77 Customer Reviews)

This did not work for my hitch. The lip of the coupler was too wide to allow the locking pin to slide up into the coupler. Unfortunately I dropped the lock and scratched the finish so I couldn't return it. I did purchase a different model that has worked well for me. Also from etrailer. 550275


Comments
The # 63227 is unfortunately not a universal-fit item. In the product description, we provide the maximum width and height of the flange or lip that runs around the bottom edge of the coupler. If the flange on your coupler is outside of those parameters, the lock wont be a fit. For reference, there are also some customer-provided photos showing a few of the couplers this lock will be compatible with. If youd care to send us a photo of your existing coupler, wed be happy to make a recommendation for a lock that will work.

I read a lot of reviews before I bought this lock. Knowing the good and bad. And after getting the lock and trying to fit it on. It didn’t fit. But I understand why it doesn’t fit and why some people return them. I myself didn’t want to return it. This is what found out with mine and my solution. When I looked at the hitch, it wasn’t symmetrical. The ball part looked fine but it was the lip or flange all the way around the hitch that wasn’t the same. The left side of the lip was shorter than the right and the front wasn’t very rounded. There is also a radius from the ball part to the flange that wasn’t quite the same around hitch. Looking at the lock, it was uniformed in and around the whole thing where it supposed to fit the hitch. Fitting the lock on the hitch was hitting the radius that was created from the manufacturer of the hitch. The lock doesn’t have this radius to match the hitch. And I didn’t want to modify the hitch because you want to keep the strength of the hitch for when you pull your trailer. To fix this I started forming a radius on the upper inside of the slot where the flange would fit inside of the lock to match the hitch radius. Started at the corners at the opening. Rounding it little by little with lots of trips back and forth just until the lock portion would fit up inside of the ball opening. Making sure I didn’t go to far to be to loose. I ended up not taking to much off in order for it to slide on. It works and fits great now. Some people don’t have to do this. That’s great. Even though I modified mine a little bit. I’m still giving it a 5 Star. There are pictures of the modification only. 490697

Doesn't quit fit! it only goes on far enough to get stuck on the 2-5/16 (Ram) brand coupler. Assuming ram is the brand. Won't go on far enough to lock. 465873


Comments
This tow ready coupler part # 63227 does fit 2 5/16 inches coupler if the width of the lip of the coupler does not exceed 4 1/8 inches. Also the height of the lip cannot be more than 5/16 of an inch. I went down to the warehouse and tried locks on the 2 5/16 ball ram brand coupler part # CA5400 and the master lock part # ML389DAT will fit your ram brand coupler.

Very disappointing. Metal on my trailer is to thick and although the lock fits well, the pin will not clear the inside and move up to the locking position. My trailer is a 2014 camper and I can only assume the metal used is thicker than most. 800411

Used them before so I know they're good. I tried to lock it for the first time yesterday and it was giving me a little bit of a hard time. So I'll see here in the next few days. 796658

This is my second Gorilla Guard. The other one is on another trailer I have used for many years. I like them because the lock is on the bottom away from rain. My order was shipped quickly and received as expected. 791593

by:

This is a good and easy lock to use. The only reason why I gave it a 4 star instead of a 5 star is it is actually fairly easy to break into. I have several of these for several different trailers and had lost the keys to one. I had to use the trailer and all I had to do was use a pry bar and the whole unit broke right in half. Other then that though the functionality is great. I have since switched to a more secure lock for some of my more valuable trailers. 696881



- 63227
by:

The lock didn't fit my trailer. There is a third measurement that is not listed that I didn't take into account. That is the distance on the outside of the ball housing. My hitch was too wide to allow the lock to completely slide on which in turn blocked the locking pin. 669857

This is an excellent product! I have used a previously purchased unit for the past 15 years without any problems. It is a very reliable performing product the protects your trailer from being towed. 658264

This item is made in China, I don't recall seeing that on the advertising website. Time will tell if it is of good quality. I would rather have bought an American made product. 638405

This Lock does not fit on any of my trailers. All are 2 5/16 couplers or various brands. I tried it on my enclosed trailer (continental enclosed), camper , dump trailer (triple crown) and boat trailer (titan brake coupler) . 539068


Comments
This coupler lock is intended to 2-5/16 inches coupler if the width of the lip of the coupler is less than 4-1/8 inches. Additionally the height of the lip cannot be exceed 5/16 of an inch. My recommendation is to check out the Master Lock part # ML389DAT

I purchased them but did not use them right away. I should have. One of the locks the keys did not open it and another one you have to wiggle and jiggle the key for several seconds to try to get it to open the lock. I have thrown away both locks since it has been so long and I knew I would never get replacements or my money back. I have many other from this company and they work great. They are several years old and still working just fine. 477310

  • Trailer Coupler Lock Recommendation for a Bulldog A-Frame Coupler # BD43805W0317
    The Fulton Gorilla Guard coupler locks, like # 63227, fit on couplers that have a lip. That is part of what holds them in place. Since the Bulldog coupler, # BD43805W0317, does not have a lip, it would require a different type of lock. A lock like # DT25013KA, would be a good choice. It fits 1-7/8 inch, 2 inch, and 2-5/16 inch couplers. Another options is a lock like # 2847DAT. This type of lock will prevent the latch from moving. I have included a video review of the lock for you.

  • Coupler Lock Recommendation for Jayco X23B Travel Trailer
    I can't recommend you modify the part # 63227 to fit the coupler on your trailer but we do have the Fastway coupler lock part # DT25013KA that we have found to be very universal and can fit almost any coupler out there. I attached a picture that shows several of the coupler styles it easily fits.

  • Coupler Lock for 2016 Jayco Jay Flight 27BHSW
    If your 2016 Jayco Jay Flight has a coupler for a 2-5/16 inch hitch ball, you will likely want to use the coupler lock # 63227. If the coupler on your trailer is for a 2 inch hitch ball, check out lock # 63228. These locks fit around the lip running along the bottom of the coupler. If your coupler does not have this lip, feel free to send me a photo of the coupler whenever you get the chance and I will be glad to make a more specific recommendation.

  • Will the Gorilla Guard Coupler Lock Fit a 2007 Airstream Safari Trailer
    In order to determine if the Gorilla Guard lock, # 63227, will fit your Airstream, you will need to take a couple of measurements. First measure how thick the lip is, top to bottom. If it is less than 5/16 of an inch, it will fit inside the lock. Next, you will need to measure the coupler width including the lip. It the width is less than 4-1/8 inches, it will fit. If your coupler has larger measurements, let me know what they are and I will try to find a lock that will work for you.

  • How to Determine if Gorilla Guard Coupler Lock will Fit a Rolled Lip Coupler
    Since there are many different sizes of rolled lip couplers, even if I tried it on one here and it worked there is no guarantee that it will fit your coupler. So we have determined the measurements that will fit the coupler lock # 63227. The overall width of the coupler, including the lip, cannot exceed 4-1/8 inches. And the lip cannot be more than 5/16 inches tall. Depending on the coupler you have, another option is to use a latch lock such as # e98886. Latch locks prevent the handle...

  • Can Multiple Coupler Locks be Keyed the Same For a Trailer Pulled by a 2005 Dodge Ram Pickup

  • Recommendation on Trailer Coupler Locks that can be Keyed Alike
    I have a solution for you, but the Gorilla Guard Trailer Coupler Lock, # 63227, is not available in a keyed alike option. I recommend the Fastway Universal Trailer Coupler Lock, # DT25013KA. The Fastway coupler lock can be used on 1-7/8, 2, and 2-5/16 inch couples. This coupler can be ordered in multiple units keyed alike. Each lock will include a set of two keys.

  • Coupler Lock Comparison for Securing a Travel Trailer
    Any type of lock you put on your trailer will be a theft deterrent. I recommend using the Fastway Universal Coupler Lock, part # DT25013KA, because it can mount on 1-7/8, 2 and 2-5/16 inch couplers and it fits on a wide variety of coupler types. The Diversi-Tech lock will be harder and noisier to break off than the Master Lock coupler lock which is a better deterrent for thieves. Wheel locks are also a secure option, but can be tedious to apply and still gives thieves a chance to hook...

  • Recommended Coupler Lock For Adjustable Ball Coupler
    The HITCH-LOCK Trailer Guard Coupler Lock by Dutton-Lainson # DL13980 is a great option for both keeping your trailer coupler locked in place and deterred from theft. You of course need an external padlock like the Master Lock Shrouded Padlock # 37DAT for this application. If you are just looking for a lock when the trailer is not coupled, I recommend the Trailer Coupler Lock - Gorilla Guard for 2" Couplers # 63228 or # 63227 in 2-5/16 inch.

  • Choosing the Correct Size Trailer Coupler Lock
    The coupler size should match the ball size it is coupling to. If you have a ball with a 2 inch diameter then you would need a 2 inch coupler lock. If the ball is 2-5/16 inches in diameter you would need a 2-5/16 inch coupler lock. For 2 inch we have the Trailer Coupler Lock - Gorilla Guard # 63228 that is featured in the video you cited. For 2-5/16 inch we have the Trailer Coupler Lock - Gorilla Guard # 63227.

  • Gorilla Guard Coupler Lock Recommendation for 2 inch and 2-5/16 inch Ball Coupler
    2-1/8 inch is not a standard hitch ball size. Because of that none of the locks we offer like the part # 63228 are going to fit. You might measure again to see if you happen to have a 2-5/16 inch ball which would mean you would need the # 63227 instead. If you do happen to have a 2 inch ball the part # 63228 would be a fit.

  • Trailer Coupler Lock Recommendation When MasterLock and DeadBolt are Too Long
