Adams Rite 4511-25-121-628 DeadLatch 31/32" Backset

Adams Rite 4511-25-121-628 DeadLatch is a robust standard-duty deadlatch designed for versatility in traffic control, making it ideal for commercial settings like hospitals and banks. Featuring a radius faceplate and a guarded latch, this deadlatch supports a 31/32" backset and comes with a 4-5/8" mortise strike. Its satin aluminum clear anodized finish not only enhances its durability but also complements various door styles. One of the standout features of the 4510 Series is the ability to retain the bolt while held retracted, allowing for two-way traffic during specified hours. This makes it a perfect choice for environments that require controlled access, such as retail stores and office buildings. The lock case, made of corrosion-resistant steel, ensures longevity and reliability. Installation is straightforward, as it can be interchanged with any MS1850A or MS1850S deadbolt of the same backset and faceplate shape without the need for stile modification. The handing is reversible without special tools, and the all-metal latch bolt is equipped with hardened steel internal pins to prevent unauthorized entry. Each unit is individually boxed, complete with the necessary mounting hardware, making the Adams Rite 4511-25-121-628 an efficient and secure choice for your locking needs.
