Abstract
This lockset has a threaded inside sleeve extending out from its central housing, the sleeve enclosing the inside spindle for the lockset. An inside rose and handle assembly is provided, the rose having inward tabs. A nut is threaded onto the sleeve and has spaced openings about its end remote from the housing, the openings each leading to a series of steps in clockwise direction progressively closer to the housing. Each step has a tread and a riser so that when the handle is brought over the spindle and the rose is maneuvered so that the tabs fit into the openings and the rose is turned in a clockwise direction, the tabs will engage the closest riser to the housing that the thickness of the door will permit. Further clockwise turning of the rose will turn the nut and move the nut closer to the housing so that the treads engage the tabs and draw the rose/handle assembly inward to firmly and quickly install the lockset on the door.
