Some time ago, Mr. JGayman raised a question somewhere on here about a better way to make the ballast box more mobile. Naturally, I couldn't help myself. Following a little conversation, some contemplation, design and stress analysis, here's the result. This one or the next one will be going to JGayman for his anticipated scrutiny. The design needs to be refined a bit to make them more affordable, but I expect they will be an upcoming product.
They could be available with either 4 casters or 6. 4 of these particular casters will support the weight but 6 just looks cool and of course will be a little better rolling and longer lasting.
Sorry for yet another "invention" rtgt
