This is a hard one to review. The product looks to be of good Master Lock quality. I could not actually use though because it did not fit my trailer hitch. It was disappointing because it was recommended by the site somewhere. eTrailer was very accommodating, offering to walk me through returning it. I can't give the lock a higher rating because I couldn't use it but it looks to be of good quality. 290823

Great lock. This is one of the best hitch locks I've bought - and I've bought many over the years. The rubber cap seals tightly and should make this last for a long time. 53181

  • Replacement Locking Hitch Pin for Subaru Bicycle Rack Made by Yakima
  • Yakima did make the Subaru-branded bike rack but they do not offer any replacement parts directly; these proprietary parts can only be purchased from Subaru. Your Forester could be equipped with either a 1-1/4-inch or a 2-inch hitch receiver. The diameter of the hitch pin will be 1/2-inch for 1-1/4-inch hitches or 5/8-inch for 2-inch hitches. You can measure the size of the receiver opening on your hitch (or the hitch pin hole itself) to determine which size pin you need. If your...

  • What is the Bully Dodge Ram Hitch Cover Made From
  • Great question! I went to our warehouse and grabbed the Bully hitch cover # CR-311 and it has an aircraft grade aluminum cover plate. The cover plate is triple chrome plated and polished. The 1-1/4 and 2 inch shank is plastic. It will fit 1-1/4 and 2-inch hitch receivers. I also recommend using a hitch receiver lock # 2866DAT for a 1-1/4 or 2-inch hitch receiver to secure the cover in the hitch and deter theft. Another hitch cover you may like is the Dodge Ram hitch cover # SHC823L...

  • How to Install the MasterLock Wireless Backup Camera and Hitch Alignment System # 4843DAT
  • To install the MasterLock Wireless Backup Camera and Hitch Alignment System # 4843DAT plug this camera into the existing 4-way on your truck and connect the trailer 4-way in line as well. Most likely your 2010 Ford F-150 has a 4-way already, however if your truck does not have a 4-way, you can use the # 18252 to install one. This hardwire kit includes a circuit tester to identify the proper vehicle wiring functions. The camera is then mounted to the rear of the vehicle. It is either...

  • Compatible Trailer Hitch Lock for a Class I CURT Trailer Hitch and Surco Cargo Carrier
  • The CURT Trailer Hitch, # 11110, is a Class I trailer hitch with a 1-1/4 inch receiver. It uses a 1/2 inch diameter hitch pin hole. All of the locks you have mentioned # 2866DAT, and # 7682 will all fit it. They will also fit the Surco Cargo Carrier, # 52017. Out of the 3 locks, I would go with # 5200. These are among our best selling locks. For the trailer hitch, CURT requires the use of a stabilizer strap, # 18050, on any non-trailer load (such as a cargo carrier or bike rack)...

  • One Hitch Lock for 1-1/4 Inch and 2 Inch Trailer Hitches
  • We do not have a locking pin with a sleeve but I do have an awesome recommendation for you. Since you would have to keep track of the sleeve any way you could use Master Lock lock set # 2866DAT. It has a 1/2 inch pin and a 5/8 inch pin that use the same lock. Instead of storing a sleeve somewhere you would be storing the pin that isn't being used.

  • Locking Hitch Pin Recommendation for Use with Curt Cargo Carrier # C18110

  • Compatibility of Draw-Tite Sportframe Trailer Hitch # 24826 With Curt Cargo Carrier # C18110
  • The Draw-Tite Sportframe Class I Trailer Hitch # 24826 is indeed a correct fit for your 2009 Honda Fit. This hitch will install without drilling using the included hardware but some trimming of part of the wheel well is needed for a secure fit. The Curt Cargo Carrier # C18110 that you referenced is fully compatible with this Class I hitch. Before loading up your cargo I suggest you check your Fit owner's manual to confirm the vehicle's tongue weight capacity (the weight loaded on its...

  • Compatability of Hitch Locks With Draw-Tite Class 3 Hitch On My 2006 Honda Pilot EX
  • I checked our records and you purchased the Draw-Tite Class III Max-Frame Trailer Hitch, item # 75599. Either of the hitch locks that you have selected, # 2866DAT and # 1480DAT will work with your 2 inch receiver hitch, in the second hole. The first hole in the receiver of your hitch is designed for a J-Pin Stabilization Pin and Barrel Lockset for 2" Trailer Hitches, item # 63201, and is not designed as the attachment point for the bike rack hitch pin. You will need to install the bike...

  • Cargo Carrier And Hitch For 2011 Chrysler 300 To Carry Folding Wheelchair
  • If you do not have a hitch on your 2011 Chrysler 300, I recommend a hitch and a cargo carrier. After doing some research on your vehicle I found that the towing weight capacity is 1,000 lbs. that means the maximum tongue weight capacity or total weight a hitch could handle is approximately 100 lbs. I recommend the Draw-Tite Trailer Hitch, part # 36548. This is a Class ll hitch and has a 1-1/4 inch receiver opening. I also recommend a flat hitch-mounted cargo carrier like the Pro...

  • Using Master Lock Wireless Backup Camera and Hitch Alignment System # 4843DAT for Hitch Alignment
  • The Master Lock Wireless Backup Camera and Hitch Alignment System # 4843DAT can be used for either hitch alignment or as a backup camera depending on where you install it on your vehicle. For use as a hitch alignment aid you will use the magnetic base to attach the camera/transmitter unit to the rear of your vehicle in a position that provides an appropriate viewing angle. This magnetic base also can be slid into the hitch receiver opening (it fits both 1-1/4-inch and 2-inch hitches)...

  • Where to Measure to Determine if Span of Hitch Lock 2866DAT Is Long Enough
  • The usable span of the # 2866DAT that you referenced is 2-3/4 inches. You would need to measure the width of your hitch to know if that would be enough. Most likely it would be pretty close.

  • Recommended Hitch Mounted Platform Carrier For 2013 Kia Sorento SX
  • The lightest carrier we offer that has the biggest shank rise and will fit hitches that are either 1-1/4 or 2 inches is the Curt Hitch Cargo Carrier, part # C18110. This carrier has a 3-3/4 inch shank rise. Since this will fit both Class ll and Class lll hitches, this may work well for your 2013 Kia Sorento. This carrier weighs only 30 lbs and has a weight capacity of 300 lbs. If you want to secure the carrier to the vehicle hitch, I recommend a Hitch Receiver Lock, part # 2866DAT....

  • Diversi-Tech Hitch Lock Recommendation for a 1-1/4 Inch Hitch
  • For a lock for your 1-1/4 inch hitch I would recommend you get lock set # 2866DAT. The Blue Ox Base-Plate-to-Tow-Bar Lock # BX8859 that you referenced is designed to be used as a lock for base-plates to tow-bars. While it could possibly be used as a hitch lock, I would not recommend you use it as one since it has never been tested for that.
