Commercial-grade Adams Rite 4510 deadlatch for narrow stile storefront aluminum doors — designed for flexible traffic control and dependable everyday use.

The Adams Rite 4510-25-101-628 is a 4510 Series Standard Duty Deadlatch commonly used on narrow stile aluminum storefront doors. It offers flexible traffic control: while the bolt is held retracted, a reverse turn of the key can retain the bolt to allow free-swinging/two-way traffic when needed. It’s also designed to be interchangeable (same backset/faceplate shape) with MS1850S deadlocks, allowing service swaps without stile modification (note: the MS deadlock is higher security).
