Round Handrail Minders are made to fit the outside diameter of your handrail. We normally stock Handrail Minders for 1-5/8″, 1-1/2″ and 1-7/8″ outside diameter (O.D.) handrails. These pieces are made from aluminum and are finished with an irridite coating that can be used as-is, in a natural silver color, or painted. Paint will adhere to the Handrail Minders beautifully. Self drilling and tapping screws are supplied with each order.
