Abstract: An elongated sheet metal bar of inverted V-shape cross-section is bifurcated at one end forming outwardly flared wings with an integral downwardly facing hook between the wings which hook is engageable with the rim of a paint pail while the wings contact the circumference of the pail below the rim to securely grasp the paint pail and hold it in upright position. The other end of the bar is inserted into a hollow rung of a hollow rung ladder with the weight of the pail causing the bar to frictionally grip the hollow rung. Serrations on the bottom of the inverted V-shape sheet metal bar adjacent the bifurcation assists in frictionally gripping the rung to secure the paint pail. A vertically mounted adjusting screw to the opposite end of the bar interiorly of the rung also facilitates locking of the bar to the ladder rung. A separate U-shaped sheet metal member functions as a wooden ladder adaptor by enveloping about a ladder side rail and hooking itself over a solid rung.
