Abstract
A resilient sleeve is provided as an accessory to enclose the space around a tubular type door lock mechanism mounted in a hole bored through a door. The diameter of the sleeve is normally larger than the diameter of the bore so that after being contracted and a pair of lugs are projected under the edge of the trim on one side, the sleeve will expand to the interior size of the bore and at the same time the lugs will engage beneath the edge of the trim.
