The SCHLAGE COMMERCIAL B502899 is a rim cylinder bar designed for use with rim cylinder locksets in commercial and institutional door hardware applications. This component serves as the connecting bar between the rim cylinder and the exit device or lock body, allowing the cylinder to actuate the locking mechanism. Installed by commercial locksmiths and door hardware technicians, the B502899 is a precision-fit part intended as a direct replacement or new-installation component where a compatible rim cylinder bar is required.
This rim cylinder bar is suited for commercial door hardware installations including office buildings, schools, healthcare facilities, and institutional settings where rim cylinder locksets are in use. It is appropriate for single-door and paired-door configurations depending on the specific exit hardware assembly. Installers should verify cylinder tailpiece compatibility and bar length against the installed hardware before ordering.
Designed as an OEM-style replacement component for commercial rim cylinder lockset assemblies requiring a standard connecting bar. Verify tailpiece and bar dimensions against existing hardware prior to installation.
Installation is typically performed by a licensed locksmith or qualified commercial door hardware technician. Before servicing, ensure the door is secured in the open position and all access to the locking mechanism is safe. Verify that the bar length and profile match the existing cylinder and exit device or lock body before final assembly. Consult the door hardware manufacturer documentation and applicable local building codes when replacing life-safety door components.
