ABSTRACT:
In a casement window, the casement fastener comprises a pivotal lever handle 5 mounted on the sash 2 through a plate 7 and a keeper 6 mounted on the casement frame 1. The keeper 6 has two similar lugs 14,15 symmetrically disposed lengthwise of the keeper plate 11. The lever handle 5 has an abutment face 10 to engage either lug 14,15 for fastening the sash, and a through slot 9 in which either lug 14,15 may be received to hold the sash in a ventilating position. The fastener may be used for right or left hinged sashes, and by the special form of keeper and handle, the fastener can be used for any required attitude of installation without concern for specially handed keepers or lever handles.
