Paint roller cover supports include axially spaced substantially rigid portions for supporting roller covers thereon and elastomeric material interposed between the substantially rigid portions that is compressed during axial movement of the substantially rigid portions toward one another to cause the elastomeric material to expand radially outward into frictional engagement with the inner diameter of a surrounding roller cover. In one form of the invention, the substantially rigid portions are comprised of a plurality of substantially rigid plastic rings and the elastomeric material comprises elastomeric rings interposed between the substantially rigid rings. In another form of the invention, the substantially rigid portions are formed by a helix of substantially rigid plastic material having a helical groove along the length of the helix containing the elastomeric material.
