Add casters to a Kobalt work bench (Part 1) - This should work for a work bench, tool cart or table

I bought a Kobalt tool cart that only has the steel legs that set on the floor. There is no easy way to move it around my garage. With space at a premium having larger items on casters is a big plus. This video shows one method to add an angle iron frame around the perimeter of the legs so casters can be bolted on only using four items that were needed to be purchased (along with free angle iron - watch to see where to obtain NO COST angle iron) will get the upgrade done without a lot of work.

Items that were bought -
The corner brackets that are large and predrilled with all the holes 4 needed from Amazon. Cost $33. LINK: https://www.amazon.com/dp/B08TGGW7YW?...
