Abstract
A paint roller frame having a wire coil female thread for attaching a plurality of different handles thereto. The wire coil female thread is formed directly in the wire frame that is used to support the roller. The wire coil female thread locks onto the rigid male threads of a handle and onto the handle to prevent accidental loosening and to also permit the user to completely replace the handle of the paint roller. The helical wire coil female thread is made of a resilient metal wire with sufficient rigidity to permits firm but yieldable direct transfer of pressure to the paint roller from a longer extension handle rather than through a permanent handle mounted directly on the wire frame. An extension member on the end of wire coil female thread enables a user to remove a handle from the wire paint roller frame without the use of a tool.
