Lend your French doors even more flair with a Euro-style cremone bolt. The surface-mounted lock shifts long rods in opposite directions to secure a door—or casement window—at its top and bottom. Von Morris
offers a dizzying array of nearly 20 different knobs and decorative rosettes for its bolts, in more than 30 hand-polished finishes. You can even order an exterior cremone that can be locked from the outside with a key. From about $1,250 in polished brass.
