I needed to move a Blanik L23 trailer over the weekend. Using my 2"
tow hitch ball and I had a heck of a time disconnecting the two. I
knew that the Blanik trailer has what I assume is a 50mm tongue.

I was kind of surprised that my 2" ball (which works out to be 50.8mm)
would be a problem disconnecting. 8/10's of a millimeter difference
doesn't seem like enough to worry about.

What is the tolerance on a 2" setup? Is it so close that 0.8mm can be
a problem?

Thanks, John


How sure are you that it was a 50mm hitch on the trailer? Did the
trailer get imported with the glider? Usually you can find 2" stamped
somewhere on the trailer if it's english. I'm sure we could fill the
newsgroup many times over with people's stories of having a hard time
either connecting or disconnecting trailers even when they are a correct
match.

With that said, the following link shows a picture of a bulldog coupler
(made by HammerBlow). I've only used this on one trailer, but it was
awesome when it came to hooking and unhooking the trailer. It looks
ugly, but it always dropped on with a snap and the way it pops loose by
swinging the jaw open when you're ready to unhook make it a piece of
cake every time. I'll convert any future trailer to this style as a
result. Don't knock it until you've tried it.
