A gallon paint can, brush, and scraper/wire brush holder for use with hollow D-rung ladders. The device includes an annular support member defining a recess into which a can, typically a standard one gallon paint can, or other container can be placed. The can, brush and scraper/wire brush are secured and prevented from falling through the recess of the ladder rung. Attached to the device is a rung insert member, comprising a smooth or ribbed tube with Neoprene washer inserts which can be inserted through the hollow rung in a snug fit, allowing the can to self-level by operation of gravity.
