Grouser ID?

[vintagebike]

Found these in a cat purchased last year. What are they? 32" x 1 1/4 square tube.

Someone must know what these fit. I have 7 of the one style and 1 with ice cleats. They look to have not been used and still are mostly primer with a bit of rust.

My 4T10 has 28" grousers

So do bolt holes line up? could b 4vl or even just a wider version

Look like grousers for a Thiokol 4T N ( narrow chassis). Let me get measurements for hole spacing off mine.
My 4T8 has a traction bar that is two square tubes, but the one you have would work just as well. The others
would be standard grousers.

Measured the grousers on my 4T8.
32 inches across and 1 1/4 square tube
Bolt hole spacing from end is
1st hole 1 1/2”
2nd hole 3 1/2”
3rd hole 6 1/2”
4th hole 8 3/4”
5th hole 11”
5th holes from each end are 9 3/4” apart
Note that the tire guides have rounded shoulders like the pictures from vintagebike!

I found a listing under Thiokol parts on eBay for grousers for either an Imp or a Sprite that are different length
and different tire guides.

vintagebike If you are interested in parting with those, let me know!

Thought I would throw in a picture of my Masters! One Trackmaster and one Snow Master!
