Corbin Russwin 509F49 Grade 1 Door Closer Bracket, Parallel with Hold-Open

Corbin Russwin 509F49 Door Closer Bracket with Parallel Arm Hold-Open Mounting

Commercial-Grade Door Closer Mounting Bracket for Parallel Arm Hold-Open Applications

The Corbin Russwin 509F49 is a professional-grade door closer bracket engineered to convert a regular arm hold-open configuration to a parallel arm hold-open closer installation. Designed for commercial door control applications, this bracket permits parallel arm or top jamb mounting on a door when the top rail is too narrow to install a closer in the regular manner. Standard with parallel arm hold-open mounting, it provides a reliable and code-appropriate solution for doors where conventional closer placement is not feasible.
