have you seen this type of tyre chock???

[carl2591]

The 2005 we purchased earlier this year had a interesting type of tire chock. Its a cast alum unit made by a company out of smithville Tenn called Kenco.

I have tried to find more about the manf but was unable. They are kinda cool and was wanting to find another one if possible.

SO do you know if the manf still exist and are they sold anywhere or just a good idea that did not get a wide following and failed.

(of course it turns it sideways)

There was an Airstreamer that passed away last year who used to manufacture that type of chock. His daughter took over the business. I don't remember her name but I think his name was Harold Hull. I believe his daughter is also a member of this forum but is not on here very often.
I'd like to tell you more but that's all the info I can remember, maybe someone else on here can steer you to her.
By the way, you have the chock upside down in the picture. It's easier to set the chock tight between the tires when you push down on the lever/handle instead of pushing up on it. Try it you'll see what I mean!

They are a great chock but if you have a tendency to forget things when pulling out they can be a problem.

Everyone does it at least once. From the picture looks like that one, bent lead screw, has been left in place once.

I have use one of those since 1994, on two different trailers. Works well.

I have a version of that with plastic/resin blocks positioned with a long screw adjusted with a knob from the top. I don't have pics but got it at an RV store for about $25. Works pretty well - certainly not as durable as what you have there though!

I have some of those and they ones I have are not build well and the aluminum is cracked. Seems like a good design just not well implemented on mine.

Here's what I have for that yellow plastic version I mentioned.

Then on the other wide of the trailer I use this:

I bought a single one of those at a yard sale a year or so ago; I'm trying to figure out what the advantage is to that versus regular wheel chocks.

They seem to help stabilize and reduce motion in the trailer, in my opinion.

Yes they still exist, I think in Indiana. At least they did when I bought one a couple years ago. Deb Kyle, the daughter of the original manufacturer makes them to order. She also makes the aluminum tongue jack foot that came with the older Airstreams.

They are much more stable than individual chocks. They are adjustable so that you can get the right tension on them between the tires. When you then pull the lever down, the trailer is not going to roll back. With regular chocks, the trailer rolls back onto the chock if you are on a slight grade. With these, you don't have to pull the trailer forward to get the chocks out after you have hooked up and it's time to go.

The problem I have with these, is they worked well with the Goodyear Marathon trailer tires, but when I switched to 15 inch Michelin light truck tires there was so much more rubber and so little clearance between the tires that the chocks wouldn't fit.

I know that they make at least two sizes of chocks since some axles are closer together than others. They also make add on plates that provide additional adjustment.

I use these chocks and love them.

They have a place for a pad lock.

[carl2591]

same with this one.. the PO left in place before taking off and bent the rod and cracked teh alum.

It's a great product but I think the alum needed is a different formula as it need to be a bit stronger like the stuff ford is using on the body panels.

regular cast alum is OK but not real tough. I just thought this was a great design and it does have hole for pad lock which is nice.

I found the original patent
https://patents.google.com/patent/US3548975A/en

I was patented by Robert Herndon in 1970. In a bit stronger material of alum this could be a winner in my book, and made in "merica".

any idea how much they cost now??
