B&W Flip Over dimensions

Can someone with a B&W Flip Over Ball measure one and give me the dimensions. I'm wanting to make an assessory to plug into the the hitch. My new truck that has the hitch in place but I have no ball for it. I need to know the dimension of the square and the height of the pin hole that secures it in place.

Interested to find out what you make.
I have the post from a Companion hitch at work. That would be tmrw though.

Also, what year/style hitch is it. Not sure, but they may have changed designs a while ago.

After trading my long bed tv that had a camper shell for a shortbed I need something to haul my kayaks on. Since the new tv has a B&W and I don't want the rack on the truck full time I figured that building something that would plug into to the B&W would be both secure and convenient. After coming up with the idea and searching for specs on B&W's website I discovered they actually manufacture one. I'll still build as I think I can build something that articulates for ease of loading and is far cheaper than B&W's premium pricing.

OK, measurements are with tape measure, dont have my calipers close.

Lower section that fits hitch hole.

radius of rounded corners.. 1.5" or 3.0" dia
square portion....... 2.5"
pin hole dia.... 0.6875"
bottom to center of pin hole 3.0"

This could be machined out of a 3" dia billet and should work perfectly. and would eliminate having to turn the radius on the corners

Thank you for the info.

I plan on using a short piece of heavy wall square tube for insertion into the hitch, then smaller thin wall tubing for the rest. I'll have to look closer at the hitch hole itself to see if the existing radius on the corners of the 1/4' wall tubing will be a fit or if I'll have to fab something up on the mill from scratch.

without my calipers kinda hard to measure, but it looks as the radius on the corners would reduce the heavy wall tubing to extremely thin corners if there is any meat left at all. probably going to require a billet to machine from, or a tube inside tube and some welding to create a thicker corner.
depends on the wall of the tubing.

2.5" square tube with .25" wall may work, but will require clearance for the outside corners.

on a side note, if you do create a "blank plug" for the B&W flip over I may be interested in purchasing one, depending on the style and cost.. I have wanted to create a "crane" to be able to lift heavy items into bed. the goose-neck mount would be a perfect anchor point. My thought was a plug that had a tab on top for bolting to.

The radius that will matter is the radius of the corners inside the hitch hole. Hoping to not have to modify the 1/4" wall tube as it has a lot more radius on it than thin wall stuff does.

So, like the USPS commercial said... "if it fits, it ships"

Really not wanting the weight of a billet.

Finally got started on my kayak rack for the truck. I used 2 1/2" x 1/4" wall square tube with the corners trimmed to 3' diameter and drilled a 5'8 hole for the locking pin 2" from the bottom. A little fine tuning and it was a good snug fit.

The plan is having a single point mount by plugging it into the BW gooseneck hitch pocket to haul my kayaks when pulling the travel trailer. The rack will tilt down to tailgate level to load/unload when not towing and swivel 90 degrees right or left and tilt down to bedside level to load/unload when towing.

The design phase is complete and most of the stock is cut. I have a few hours of time coming up on the mill to make the swivel and hinge joint parts before moving on to assembly.
