TJ51 Door Closer - Top Jamb NHO

The 51 Series is a light-duty commercial surface door closer for interior doors in retail, office, and multi-family applications. Its compact cast-aluminum body and integrated full cover provide clean aesthetics at a value-engineered price point.

ANSI/BHMA A156.4 Grade 3 certified, the 51 covers doors up to 125 lbs with adjustable spring sizes 1 through 4. The 51 (NHO) and 151 (HO) are the standard regular-arm offerings; TJ51 and TJ151 are top-jamb-mounted variants for doors where parallel or regular-arm mounting is impractical.

Separate sweep and latch speed valves, non-handed field-installable arms, and ADA-compliant low-force versions make the 51 Series an easy specification for tenant improvements and light commercial retrofits. Covered by a 2-year limited warranty.
