This one fits all current North American stepladders 6' or taller and all D-rung ladders, whether extended (when it has to attach to one rung) or doubled (when it has to engage two rungs). It also has to accommodate the range of angles that ladders can safely be used at. This holder does all that, holding either quart or gallon cans securely.
Easy to move with one hand from step to step, it also has a strong magnetic brush holder mounted directly over the open can so you always have a hand free to grip the ladder. Cans are easily attached using a specially designed mono-polymer belt to accommodate both small and large containers.
Made from galvanized steel rod, it weighs only 9 oz. Patented.
