Video Transcript for Blue Ox Trailer Hitch Receiver Lock Product Line Review

Today we're going to be taking a look at the Blue Ox Receiver Lock. We've got three different sizes. For the Class 4 and 5 we've got the 5/8" extra long pin here. That part number is BX88212. Here in the middle we've got the Class 3 or Class 4, that's going to fit up to the 2" shank. This part number is BX8858.

We also have part number BX8859, this is for or Class 1 or Class 2. This one offers the 1/2" shank design. As you can see these are going to be perfect for securing your Blue Ox tow bar, ball mount, bike rack, cargo carrier, whatever it is you need to secure onto your vehicle and don't have to worry about unintentional disconnect or somebody taking it. Completely made in the United States. They put a nice chrome finish on it. It's going to give us a good, long lasting, good looking product.

There's a dust cap here on the end. That protects our cylinder style lock from any damage, dirt or debris getting inside of there. There's a couple different spots here you can see they've got a really nice nurled 00:01:18 or textured finish to it. It's going to help us get a good grip on it as we're trying to operate it in maybe some more extreme or inclement weather. As you can see here a cylinder key, just slide in 1/4 turn, we're going to have this release. This isn't like some of the other receiver hitch locks where you have to continually turn your key and thread that down on there. It's going to operate just like a standard hitch pin.

We'll slide it through, whether it's our tow bar, our ball mount or bike rack, whatever else it is, put the cap on, quarter turn the other way. As you can see it's nice and secure and we're ready to attach our vehicle to the back of our RV, we're ready to attach our trailer to our ball mount, or load up our cargo carrier and head down the road. Now that we've taken a good look at them and we've seen how they're going to work and how they're made, that will complete today's look at the Blue Ox Series of Receiver Locks. .

The hitch pin itself appears to be a well-made, functional product. My problem is that I purchased it for my 2018 Chevy Duramax 2500HD. As those of us who own 2500HDs know, the hitch receiver is a 2.5" receiver rather than a 2", so that it can accommodate Class V hitch equipment. Most locking hitch pins are too short to work effectively which is why I purchased this one. Unfortunately, it appears that the way the tow-chain holes on Chevy's hitch are positioned, this pin blocks the use of the holes with the chain/hook makeup I've got. Will probably need to purchase shackles for the chains to make everything work correctly. 496029

Used for one year. Product is sturdy and works well. No problems. Rubber dust cover could be revamped for easier use, but very minor detail. 670402

Nice product everything I expected 663081

- BX88212

Well I ordered this item from you because the hitch on my truck is 4” wide. I could not find a locking pin long enough that would fit my hitch locally. I tried at several Walmart stores and several Auto part stores and nothing. So I went to the internet and found this the BX88212 and it is just what I needed. It’s on my hitch and I’ll use it every time I pull my ATV utility trailer or my RV. Now I know where to look if I need anything else for towing. That’s at etralier.com. Thanks you and I really appreciate it!! 633758

The pin locks have 20,000 miles on them pulling a toad. Still working great and open easily every time.

The pin is very heavy and I am very comfortable using it with my camper. I was concerned about buying a cheap inferior product that would not do the job. This is a quality name and great price. I hope I can buy a 2nd one keyed the same. 155104

still awesome

Solidly build and key works although it is not as pictured. The product I received had a round key not a standard "toothed" key. 112326

We do have a couple options that are slightly longer, but they feature uniquely threaded ends that are only designed to fit certain model bike rack shanks. I have attached a short video...

  • Three Locking Hitch Pins for Class V 2-1/2 Inch Hitch Receiver that Can be Keyed Alike
    We do have a way for you to lock your ball mount to your hitch receiver but unfortunately, the Blue Ox # BX88212 is not able to be keyed alike. For another solution,our etrailer.com lock # e98881 fits 2-1/2 inch Class V hitch receivers and can be keyed alike. Just select the drop down to do so on the product page when ordering. Hitch pins don't actually bear any of the trailer's weight so they are not given a weight rating. They are tested to be used with a Class V hitch and therefore...

  • Keyed Alike Trailer Hitch Lock for 2-1/2 Inch Trailer Hitch
    Although there is an option for a trailer hitch receiver lock for a 2-1/2" trailer hitch that you can get keyed alike, the Blue Ox Trailer Hitch Receiver Lock # BX88212 is not one that you can get keyed alike. I recommend the Trailer Hitch Receiver Lock - Extra Long - Flush Design for 2-1/2" Trailer Hitches # e98881 which has a keyed alike option. To order them keyed alike, just hit the "Keyed Alike" option in the drop-down box on the product page and enter the quantity you need. I...

  • Locking Adjustment Pins for the B&W Tow & Stow 2-Ball Mount Part # BWTS10037C
    Yes, in order to prevent the adjustment pins part # BWTS35010 from being stolen on your B&W Tow & Stow 2-Ball Mount part # BWTS10037C you are going to need a hitch pin lock that has a 5/8" diameter and at least 4-1/2" span. For this, I recommend the Blue Ox Trailer Lock part # BX88212 which is one of the very few options that meet the above criteria. Please keep in mind that the built-in channel prevents removal of the platform when the ball mount is installed, which will help prevent theft.

  • Longest Trailer Hitch Lock for 10 Locks Keyed Alike
    The Blue Ox # BX88177 consists of two 1/2 inch diameter and 2 5/8 inch diameter pins. They are only able to have the 4 keyed alike. The measurement is 4-3/8 inches between the opening like # BX88212 which cannot be keyed alike . The only option to get all ten keyed alike is to use the DeadBolt Trailer Hitch Receiver Lock - Extra Long - Flush Design for 2-1/2" Trailer Hitches # e98881 which measures 3-5/8 inches between the outside cylinders. I've attached photos to assist.

  • Locking Hitch Pin for 3 Pins on B&W Tow & Stow Ball Mounts for 2-1/2 Trailer Hitch
    The Bulldog Hitch Receiver Lock # BD580412 that you referenced is a little short for the adjustable part of the B&W Tow & Stow 2-Ball Mount # BWTS20037B but we do have something that will work instead. The Blue Ox Lock # BX88212 measures long enough to fit the Tow & Stow!

  • Recommended Trailer Hitch for a 2019 Nissan Titan SV
    Out of the Draw-Tite # 76154 and the Curt # C13304 trailer hitches I recommend the Curt option for your 2019 Nissan Titan SV because Curt tends to have stronger welds and a thicker powder coat which gives it better protection. Both options have the same weight ratings and so it really boils down to construction, for which Curt takes the prize. Since most people who install trailer hitches on pickups typically use it for towing you'll also need wiring and a ball mount to complete a towing...

  • Long Locking Hitch Pin Needed for Class V Trailer Hitch on a Chevy K2500 Pickup Truck
    You might be able to use Blue Ox pin # BX88212 which measures 4-3/8 inches between the ends so it will work. The best way to measure to ensure the clearance needed is to use a tape measure that is small enough to fit through the hitch pin holes. Then measure the outside to outside width of the hitch that way.

  • What Does the Span of a Locking Hitch Pin Refer To
    The span of a locking hitch pin like the Blue Ox # BX8858 means the amount of space that can fit between the two walls of the hitch receiver- so yes, basically the distance from the outside wall of one side of the receiver to the other. We have noticed that certain Toyota factory hitches have a thicker walls on their receivers that measure 2-7/8" instead of just under 2-3/4" so if you've got a Toyota truck with a factory receiver you would need to use a locking hitch pin like the # BX88212...
