The SARGENT 25UO EN is a door closer arm designed for use with the 351, 281, and 1431 series door closers. It supports universal mounting configurations including parallel arm, standard arm, and top jamb installations, giving installers flexibility across a range of door and frame conditions. Finished in sprayed aluminum, the arm provides a clean, consistent appearance suited to commercial and institutional applications. This component is installed by licensed door hardware technicians or commercial locksmiths as part of a complete door closer assembly.
This arm is appropriate for commercial door installations where multiple mounting orientations are required. The universal design allows the same arm to serve parallel, standard, and top jamb configurations, reducing the need to stock separate components for different job conditions. It is commonly specified on hollow metal or wood door frames in office buildings, schools, healthcare facilities, and other commercial construction projects where SARGENT 351, 281, or 1431 series closers are in use.
Designed for use with SARGENT 351, 281, and 1431 series door closers in parallel arm, standard arm, and top jamb mounting configurations.
Installation should be performed by a qualified door hardware technician or commercial locksmith familiar with SARGENT closer systems. Verify the mounting configuration - parallel, standard, or top jamb - before fitting the arm to the closer body and door or frame. Follow the closer manufacturer's template for hole layout and fastener placement. Ensure the door is held open or properly secured before removing the existing arm or closer hardware.
