  • Right Angle Lock for RockyMounts MonoRail
    Hi Jeff; is the problem that the lock end won't fit in the space you have on the Tesla or that you're unable to lock it? When I reached out to RockyMounts they said they have had dozens of customers use the Curt 23504 which has the same locking end as the 23502 you have right now. If you weren't able to get it to lock onto the end I would give it another try since that is their best solution. If not, I can see if I can pull one of the racks and try out a lock like the # 1479DAT you looked...

  • Locking Hitch Pin For Hitch On 2024 Tesla Model Y With Limited Room Around Receiver
    Hello Jason, thanks for reaching out. I do have a potential solution for you, but we are not aware of a locking pin that is made specifically to be compatible with the hitch on a 2024 Tesla Model Y. Your Best option for this will be to use a lock with a swivel head design like the Master Lock # 1479DAT. This allows the face of the lock to stick straight back instead of off to the side which makes operating the lock much easier with limited clearance. The overall length of the lock is 5-3/8"...

  • Does the Trailer Hitch Lock # e98880 Have Rubber Grips on Each End
    The black rubber grip is just on the one end of trailer hitch lock # e98880. The other end has a rubber cap that covers the key hole but no rubber around the rest of the locking piece. Master Lock hitch lock # 1479DAT is more like what you have described.

  • Trailer Hitch Pin Lock for a 2009 Ford Explorer with Little Space to Use a Lock
    I have not heard of this exact issue before on any vehicle. Certainly, you can use a hitch pin/lock in any orientation that works for you.

  • Why Doesn't Masterlock Hitch Lock part # 1479DAT Have Towing Capacity
    The Masterlock Hitch Lock part # 1479DAT does not have a specified towing capacity. Reason being that rarely does the hitch pin bare the weight of the trailer it's towing. The tongue weight of the trailer binds the ball mount up in the hitch which provides nearly all of the horizontal resistance to prevent the ball mount from sliding out.

This lock is designed to fit all 2 inch trailer hitches and is also designed to work with OEM trailer hitches that have limited clearance for a hitch pin because the hitch pin hole sits close to the hitch crosstube.

  • Can I Tow A 2018 Chevy Equinox Using A Maxx Tow Dual Hitch MT70070
    The Roadmaster Dual Hitch Receiver Adapter # RM-077-8 that you referenced is designed for flat towing vehicles and an additional accessory like a bike rack, for example, with the additional 2 x 2" opening. It does provide an 8" drop and you will not need an additional receiver to accomplish this. It allows your tow bar to set level as you flat tow the vehicle.
