ABSTRACT:
A one-piece pull comprises a generally box-shaped one-piece part having an opening in a face thereof, a pair of opposing side walls, a bottom wall and an upper wall, with the side walls, upper wall and bottom wall each having flange members formed integral therewith to facilitate the flush mounting of the pull to a panel. The pull is provided with a channel on an upper surface thereof and a plurality of boss members on a lower surface thereof, which facilitate the proper positioning of the pull relative to the panel. At least one retaining member is formed integral with a lower surface of the pull and comprises a support member and a resiliently movable leg member extending from the support, wherein upon insertion of the pull into an aperture in a panel, the resilient leg member flexes to permit passage of the panel and then returns to a substantially unflexed position with a snap-like action, whereby the panel is retained in sandwich relation to the bottom flange and the resilient leg member.
