Abstract: A paint roller assembly has adjustable arms for accommodating various sizes of roller cages and accompanying roller skins. The assembly includes an elongated cage. An elongated roller skin has a main body, an open first side, and an open second side wherein the main body, the open first side, and the open second side define an interior space configured for receiving the cage wherein the cage is slidably insertable into the interior space of the roller skin. A pair of arms is selectively couplable to the cage. A head is selectively coupled to each of the arms. A first and second side of the head is selectively couplable to a second side of each of the arms. A slot extends from the first side and the second side of the head wherein the second side of each of the arms is selectively insertable into the slot.

Abstract: A chair supports rebar or wire mesh during a concrete pour. The chair is box shaped having grooves in the side walls of different width for supporting rebar of different diameter. Notches in the edge of the grooves on opposite sides of the chair support wire mesh of different diameter. The notches are shaped so the wire mesh is snapped into the notch. Wall like braces extend across the inside of the chair and support the grooves from the opposite wall. The larger grooves are on the short sides of the chair to raise the rebar a longer distance off the underlying surface. In a preferred embodiment, the chair provides two elevations for placement of rebar, namely 2″ and 3″ above an underlying surface. Parts of the box are cut away to promote concrete movement through the chair. Slots are provided to allow air trapped in the concrete to escape from the chair.
