Sargent 351 UO Powerglide® Door Closer | Heavy Duty Universal Arm

The Sargent 351 UO Door Closer is the premier choice for high-traffic, institutional applications that demand the absolute highest level of durability and control. As the flagship model of the Powerglide® series, the 351 UO is engineered for a lifetime of performance in schools, hospitals, and high-use commercial buildings. This "one-box" solution features the UO Universal Arm, allowing for Regular, Top Jamb, or Parallel Arm mounting configurations right out of the box.

Constructed from a heavy-duty, one-piece die-cast aluminum silicon alloy (with 14% silicon content), the 351 body offers superior strength and corrosion resistance. Its heat-treated full closed rack and pinion mechanism provides total control from a full open position. With adjustable spring power from Size 1 to 6, this closer easily accommodates everything from lightweight interior doors to heavy exterior perimeters while remaining fully ADA compliant.
