Abstract
A paint applicator roller formed of a plastic molded cage made in two elongated matching halves which are aligned to form a roughly cylindrical shape for inserting within a tubular applicator core having an outer applicator surface. The axle of the handle frame is journaled within central bearing forming bores located within the cage. The distance between the bearings is less than one-half the length of the core so that the axle is considerably shorter in length than the core. The two cage halves may be opened, i.e., separated, or may be closed, i.e., radially aligned about the frame axle for rotatably mounting the cage upon the axle.
