  • Recommended Lockable Gooseneck Coupler Inner Tube And Padlock
    Yes, the Bulldog BX1 Gooseneck Coupler Inner Tube - Round - 2-5/16" Ball - 25,000 lbs # BD1289020300 is lockable with a standard padlock. I recommend the Master Lock Laminated Steel Padlock- 1-9/16" Wide- 3/8" Shackle - Blue Cover - Keyed Alike # ML312KA for a little less metal on metal rattle.

  • Can the MasterLock Hidden Padlock Be Ordered Keyed Alike
    I may have a solution for you, but the Master Lock Hidden Padlock part # ML6271 cannot be ordered keyed alike. However, we do have some heavy duty padlocks with a 3/8" shackle that can be keyed alike that can provide a comparable solution. I recommend looking at the Master Lock Laminated Steel Padlock- 1-15/16" Wide - 3/8" Shackle # ML312KA, which is also a durable padlock option, but doesn't have the hidden design for the added layer of theft protection. This is available to keyed alike...

  • Padlock Recommendation for Lid of Carpod Walled, Folding Cargo Carrier # M2205-01-02
    Carpod recommends 3/8 inch diameter shackles with the 24x48-3/4 Carpod Walled, Folding Cargo Carrier # M2205-01-02. So for that # ML312KA would work well. This padlock is laminate covered so it will fight corrosion.

  • Comparing 2019 Chevy 3500 OEM Compatible 5th Wheel Hitch for Biggest Trailer
    The difference you asked about you already stated. The B&W Companion OEM 5th Wheel Hitch for Chevy/GMC Towing Prep Package - Dual Jaw - 25,000 lbs # BWRVK3705 is rated for 5,000 lbs more than the other hitch. It will be a stronger option with less limitations due to that. The lock that will work with the hitch to secure it is the Master Lock Padlock # ML4140KALH for a single lock or, if you want to lock both sides of the Companion, you can use the Master Lock keyed alike # ML312KA. The...

  • Recommended Solution to Get Both Padlock and Hitch Lock Keyed Alike to Use Single Key
    I may have a solution for you to have all of your locks keyed alike, but you won't be able to do this using a Master Lock Padlock like the # ML312KA and the Threaded Anti-Rattle Hitch Pin Lock for etrailer Cargo Carriers - Keyed Alike # e99047. I'll also add that these types of locks are going to use two different types of locks, so having them keyed alike does present a unique challenge; however, BOLT makes locks that can be keyed specifically to the ignition key of your vehicle and would...

  • Parts Needed for Keyed Alike Lunette Ring, Gooseneck Coupler, and Hitch Ball Coupler Locks
    To add locks to your trailers that have the Lunette Ring Couplers (which connect to pintle hitch receivers) you will want to use 2 of part # BLTL-60.

  • Covered Carrier Recommendation for Jeep Wrangler and Unity Leisure Travel RV
    I do have a solution for you but it is a little bit of a different style than the Rola # 59109 or the Thule # TH665C. For your application I recommend the 24x48-3/4 Carpod Walled, Folding Cargo Carrier # M2205-01-02. This is essentially a cage that comes with a bag to help protect your cargo against the weather. You can add a lock to the cage with the Master Lock # ML312KA and then you can lock the shank of the carrier with the part # 63232. As for rear clearance on your Jeep and RV we...

  • What Swinging Covered Locking Cargo Carrier do You Recommend for My 2021 Ford Bronco?
    I have a great option for you. As far as a swinging option, the Rola Swinging Enclosed Cargo Carrier for 2" Trailer Hitch # 59109 and the Yakima EXO Swing Away # Y62VR are the only enclosed cargo boxes we carry. Both of these, while being amazing options, are not the vinyl locking ones you seem to be looking for on your 2021 Ford Bronco. For a great locking carrier, the best option is the 24x48-3/4 Carpod Walled, Folding Cargo Carrier - 2" Hitches # M2205-01-02. While not made of vinyl,...
