Designed for 1-3/4" thick doors, this curved deadlatch paddle features a sleek satin aluminum clear anodized finish, enhancing both functionality and aesthetics.

Available in multiple configurations-push, pull, left, and right-the paddle can be easily handed in the field to suit specific installation needs. For added versatility, the 4591 paddle can be equipped with a monitor switch, which can either drop low voltage power to an electric lock or serve as a request-to-exit signal. With a standard dogging device to maintain the paddle in an unlocked position, this paddle operator is the ideal choice for both commercial environments and discerning homeowners looking for a reliable door hardware solution. Individual units are packaged with mounting hardware, ensuring a straightforward installation process.
