Round Hitch Coupler Advice

I am in the process of building a new frame for a 48 Liner.
the factory frame is a pipe frame with 3 1/2 pipe.
I need to find a new hitch coupler for the front and was wondering if anybody knows, where to find one.
the only round ones i can find are a new to me design and are just like this :


Bulldog 028383 Round Straight Mount Coupler 5000 Lbs | eBay


anybody used this design yet ? any thoughts of where i can find a traditional coupler ?

Bulldog couplers have been around for decades. I've seen pictures that show some of the original Torpedos had them installed.
Good choice for keeping the Vintage look.

I have used Bulldog couplers for years on every type of trailer one can imagine. Along with farm implements.
They are of solid design and tough. I don't think you will be disappointed if you decide to use one.
If there ever comes a time when I need to replace the original Marvel coupler on my '74 Argosy. It will be with a Bulldog coupler.

I have a book on Bulldog couplers which I picked up at an Antique store. The book dates from the mid 1930's. The design now is very similar to the design then. I would certainly not hesitate to use one.

would you guys think the 5000lbs coupler is sufficient or should i use the larger size with the 2 5/16 ball? the larger one has a larger pipe on it and might be easier to weld to the new frame though i think

The original size was most likely 2" but if 2 5/16 is easier for you to install I would use it. It is the most common size trailer ball these days anyway for larger RV's and by using it, you would have more flexibility with your hitch to tow other rigs.

thanks guys for the info. I was just unfamiliar with that type of coupler.
i will more than likely go with the 2 5/16.
they do make two styles though.. one with the lever and one without the additional lever to lock it. the additional lever requires some more length , but i guess it will be better to use.
does anybody knows the outside pipe diameter of this coupler ? i can’t seem to find it on the web

The inside diameter of the tube is 1 3/4". It is shown on etrailer.com. No outside dimension is shown. I would guess it is @ 2 1/4".

That's smaller than I thought. The pipe frame has an ID on 3 1/2" . Probably got to use some sort of sleeve / reducer
