The 4531-16-628 from Adams Rite is a standard duty deadlatch with a radius faceplate in clear anodized finish. Designed for maximum flexibility in traffic control during and after business hours, this deadlatch offers a unique feature allowing the door to be free swinging with two-way traffic. This is particularly beneficial for environments such as hospitals, banks, and stores that require specific entry and exit protocols. While it is compatible with older models like MS1850 Deadlocks and 4250 Deadlatches, it should be noted that it does not match the maximum security level of the MS Deadlock.
