About Wheel Sizes
Smaller casters with a 2 1/2-inch diameter were used starting with the shorter versions of the self-contained system in the later 1990s. On December 1, 2006, the Triton Series units began using larger 3-inch casters. The Classic Series systems began using the 3-inch casters in June of 2007.
