Video Transcript for Tow Ready Locks 63228 Review

Today we're going to be taking a look at part number 63228. This is the Tow Ready Gorilla Guard Trailer Coupler Lock for 2-inch couplers. This is designed to fit most 2-inch couplers. It's going to feature an easy, single action key that's going to be this portion here. All you have to do is place that in, push it a little bit and then give it a turn. That's going to disengage the pin, allowing this portion here to fit around the socket of the coupler.

This needs to go around the lip that surrounds the base of the socket. Once you get that on there, you don't even have to have the key installed in order to lock it back in place. All you have to do is push this up. This is going to go around the inside lip of that socket where your hitch ball goes. In between this portion here is going to be the down portion of the front of the socket. Again, that's where your hitch balls are going to go.

That's going to prevent this from being able to back off of the coupler. This is designed to protect unattended trailers. It's going to come with 2 keys that use a pick-resistant design. Down here you can see the support system. This design shields the lock from tampering devices.

It's going to be made from a steel construction with a nice protective finish to stand up well against rust and corrosion. The lock an the pin assembly are steel as well and appear to have a nice zinc coating on them. Again, this is designed to fit most 2-inch couplers. A few measurements to go over real quick with you to see if this is going to fit your coupler. The coupler width, including the lip, must not exceed the inside measurement here, which is going to be 3-13/16 of an inch. It also cannot exceed the height that this portion gives us right here of the lip, which is going to be 5/16 of an inch.

Now replacement keys are available. You can find those right here at I'm going to go ahead and show you how this would install. I have a 2-inch coupler here today. The measurements fit within the measurements that I listed. All we have to do is place this around the lip, push up on the pin. Even though the swivel's a little bit around that socket portion, around the lip, it's still engaged with that pin here on the underside. It's going to prevent the lock from being able to come off and it's going to prevent anybody from being able to hook up to our trailer. That's going to do it for our review of part number 63228. This is the Tow Ready Gorilla Guard Trailer Coupler Lock for 2-inch couplers. .

I purchased my trailer used, but in excellent shape and the seller had the Gorilla Guard Trailer Coupler lock on the unit. He would not let the lock go with the trailer and spoke so highly of it, I purchased my own. I could not be more pleased with the product or Their service was speedy and flawless and the price of this item ranged widely from several vendors and their price was the best by far. 45486

Ask the Experts about this Tow Ready Locks
Do you have a question about this Lock?

  • Coupler Lock Comparison for Securing a Travel Trailer
  • Any type of lock you put on your trailer will be a theft deterrent. I would recommend using the Diversi-Tech Universal Coupler Lock, part # DT25013, 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. The Master Lock Coupler Lock, part # 378DAT, you referenced will only fit couplers for a 2-5/16...

  • Replacement Keys for Fulton Trailer Coupler Lock
  • We do offer replacement keys for some Fulton coupler locks under certain circumstances. You will need to know the key number and the color of the original key. If the lock uses a gold colored barrel or tube-style key, and the key number does NOT start with the letters AG, AZ or H, the replacement key would be part # CKEY-BG. If the key meets the above requirements but is silver in color, use part # CKEY-BS For a flat silver key, whose key number does not start with the letters mentioned...

  • Selecting a Secure Coupler Lock
  • The purpose of any lock is to keep honest people honest. If the potential thief is determined, any lock can be eventually defeated. The key is to make defeating the lock as difficult, time consuming and noisy as possible. The design of Gorilla Guard Coupler Lock part # 63228 helps make defeating it more difficult than other locks because the actual locking pin is inaccessible when the lock is in place. The fact that this lock uses a barrel style key instead of a flat key also makes the...

  • Coupler Lock Recommendation for a 2014 Jayco White Hawk
  • The Gorilla Guard part # 63227 would be an excellent choice for your 2014 Jayco White Hawk 28DSBH as long as the coupler on your trailer is designed to fit a 2-5/16 inch ball, the coupler width is not wider than 4-1/8 inches and the height of the coupler lip is not greater than 5/16 of an inch. If you had a 2 inch ball coupler you would want the 2 inch version of that lock, part # 63228. Another very popular and well-reviewed coupler lock is the Diversi-Tech Trailer Coupler Lock part...

  • 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.

  • Coupler Lock Recommendation for a 2015 Jayco White Hawk 27DSRL
  • If the coupler on your 2015 Jayco White Hawk 27DSRL has a lip that does not exceed 3-13/16 inches and is not thicker than 5/16 inches the Gorilla Guard Coupler Lock part # 63228 that you referenced would work well for you. Check out the review video I attached for more info.

  • Which Coupler Lock Would Best Fit my 2-5/16 Inch Coupler with a 3-3/4 Inch Wide Lip
  • The Gorilla Guard for 2 inch couplers, part # 63228, would be so snug it would not be easy to get on and off, not to mention the curved portion up front may not fit the larger 2-5/16 coupler nose. The Gorilla Guard for 2-5/16 inch couplers, part # 63227, would be a better fit, though it will accept couplers of a greater width than yours, it should not be loose enough that it would not be able to prevent theft. You could also look into a different style of lock. I have included a...

  • What Materials are the Gorilla Guard Coupler Locks Made Of
  • I called the manufacturer regarding the construction of the the Gorilla Guard Locks, part # 63228 and part # 63227. The main portion is a black-painted SAE-903 spec. steel casting. I pulled the lock from our warehouse to take a close look. The lock and pin are cast as well and appear to have a zinc coating. The keys are brass.

  • 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.

  • 2 Inch Trailer Coupler Locks that Can be Keyed Alike for a Fleet of Trailers
  • We have several coupler locks for 2 inch couplers that can be ordered keyed alike but the Gorilla Guard # 63228 is not one of them. I have included a link for you to the ones that can be ordered keyed alike. A lock such as # TCL3-YL is similar to the Gorilla Guard. You would just select the keyed alike option, near the add to cart button on the product page, select the quantity and they will all be keyed the same.

  • Replacement Key Recommendation for a Gorilla Guard Coupler Lock
  • For the Gorilla Guard coupler lock the replacement key is # CKEY-BS. You will enter the key number on the page. The key number should be on your existing keys or on the face of the lock. Replacement keys are not available if the key number starts with AG, AZ, or H or if the original keys were a color other than silver. If you can't find the key number there's really no way of knowing what replacement key number would work for you.

  • Coupler Lock Recommendations for a Titan Multi-Fit Coupler
  • You will need to take a couple measurements on your Titan coupler to be sure it will fit, but I would recommend you get a Tow Ready Gorilla Guard # 63228. This lock will slip on the front of your coupler and should work well as a theft deterrent. The width of your coupler (including the lip) should not exceed 3-13/16 inches and the lip should not be thicker than 5/16 of an inch. Another option you have would be the Master Lock Universal Trailer Coupler Lock # 379DAT, this will work similar...
