Presented is a slidable deadbolt security device designed for installation with a sliding glass door or sliding glass window. The slidable deadbolt security device is fastened to the threshold in association with the leading edge of the fixed door portion of a slidable door assembly. A deadbolt is manipulable to engage or disengage the sliding door portion. The relationship of the slidable deadbolt and the sliding door frame is such that the deadbolt cannot be disengaged from the sliding door frame unless the sliding door is completely closed. In an aspect of the invention relating to sliding glass windows, the slidable deadbolt is slidably mounted on the windowsill adjacent the leading edge of the fixed window portion of the window assembly and spaced laterally from the fixed window frame to enable the slidable window portion to move therebetween. An aperture in the frame of the sliding glass window, or in a flanged bracket attached to the trailing edge of the sliding glass window portion, receives the deadbolt, permitting the window to be partially opened a predetermined amount, but prevents further opening, prevents manipulation of the deadbolt to release its engagement with the window frame or flange, and prevents lifting of the slidable window from its track.
