These Dog Bone caps are a reproduction of an original aftermarket accessory that were available during the Model T era. These cast chrome caps have a hole drilled in them for use with Jr. Moto-Meters and are 6-1/4” long. The Dog bone style makes removing your radiator cap easier by giving you a more convenient area to grip and to twist turn the hot cap, as the arms are outboard and they cool off in the air. Many people like using it to add some style to your Model T.

Overall Assessment

Customers praised the product for its superior quality, particularly the solid plating. Usability is straightforward with a good fit for Model T radiators, underlining its practicality. Aesthetic appeal is evidently excellent, especially when paired with a motometer. However, some reported the need for a little adjustment for perfect alignment. One customer valued it so much they bought another one for use with a motometer for added functionality. One minor drawback noted was the absence of included gaskets. Nonetheless, the product's quality and practicality leads many customers to highly recommend it over competitors.

This is the second one I bought. The first one was so impressive I had to order the one I could put that fancy little motometer on. It will be cool to look at for temperature while driving my T-Bucket

This cap looks real good once you figure out how much gasket thickness you need to get the dog bone to line up correctly (I ended up using a 3/16" thick O-ring). My first cap I broke off one of the dog bones trying to get it tight enough to line up (totally my fault, I do not blame the product for my stupidity). Please use a wrench.

Dresses up the radiator neck very nicely. A shame it doesn't come with gaskets. Believe they are [$] for a pack, yet $7.95 to mail them.
