Sargent 351-O TB EN Surface Door Closer, Standard Arm, Thru Bolts, Sprayed Aluminum Enamel

Sargent 351-O Surface Door Closer — Standard Arm, Thru Bolts, Sprayed Aluminum Enamel

The Sargent 351-O is a heavy-duty surface-mounted door closer with a standard arm configuration, part of the proven 351 Powerglide® Series. The standard arm (also called regular arm) mounts on the pull side of the door, making it the most common and versatile installation for interior and exterior commercial doors.

Compared to the parallel arm (CPS) version, the standard arm provides a more compact footprint and is ideal for openings where door swing is not restricted and a compression stop is not required.
