Deerfield Patio Door Lock

JSK Inc. introduces the patent-pending Deerfield Patio Door Lock for metal sliding doors. This lock resists forced entry or removal of the sliding door from its tracks by the sheer action of its design. Made in the USA from all zinc casting, the lock is powder-coated for long life and available in white or bronze finish. It installs in a few minutes and installation instructions are available.
