Product Details

Sargent 351 UO Door Closer - with Universal Arm package

UO - Universal arm package provides brackets and arms to install closer in standard, top jamb or parallel applications

351 Series: Heat treated full closed rack and pinion provide control from the full open position. Heavy duty one piece die cast aluminum silicon alloy body with 14% silicon provides superior strength and wear resistance. 1/2" arm engagement over a 7/16 square spindle ensures a wear-resistant tight joint.

Valves: Brass body low sensitivity control valves offer separate regulating for door speed, latching, backcheck and optional delayed action. All valves are controlled by an 1/8" Allen wrench to discourage tampering and are captivated to prevent removing valves from the body and damaging door closer. Adjustable backcheck protects the door and hardware from damage during the opening cycle.

DA - Delayed action valve (Optional): Holds the door in the open position momentarily - 20 second minimum hold open delay - Beneficial when moving carts or objects thru door opening and ADA applications

About this item

The Sargent 351-UO is a Grade 1 heavy-duty surface door closer from the Powerglide 351 Series, shipped with the Universal arm package. The "UO" is the part worth understanding before you order: it's the universal arm tri-pack, which means one box gives you the brackets and arms to mount the closer three different ways, regular (pull side), top jamb, or parallel arm. Instead of guessing the mount and ordering an arm-specific model, you get a single closer that adapts to the opening in front of you. For contractors and facility managers who don't always know the exact mount until they're at the door, that flexibility is the whole appeal.

 

What the 351-UO universal arm gives you

 

A lot of closer returns happen because someone ordered the wrong arm for the mount. The 351-UO side steps that. The universal package includes everything to install regular, top jamb, or parallel, so the same closure covers a pull-side hinge mount, a frame-face top jamb mount where the door has no room, or a push-side parallel mount for a cleaner look. The closer body itself is non-handed, so it works on left or right swing doors with no separate part to specify.

That versatility is why the 351 series shows up across schools, healthcare facilities, offices, and commercial buildings. One closer SKU can standardize a whole building's openings, which simplifies both ordering and the parts you stock for maintenance.

 

Sargent 351-UO specifications

 

  • Grade: ANSI/BHMA A156.4 Grade 1, heavy-duty.

  • Body: One-piece die-cast aluminum-silicon alloy, rack-and-pinion operation.

  • Arm: UO universal package, mounts regular, top jamb, or parallel.

  • Spring power: Adjustable size 1 through 6, set to size 3 at the factory.

  • Valves: Front-facing brass valves with separate adjustment for closing speed, latch speed, and backcheck. Optional delayed action available. Valves are captivated and adjusted with a 1/8 inch allen wrench to discourage tampering.

  • Backcheck: Adjustable backcheck standard, protecting the door and frame during the opening swing.

  • Fluid: All-weather hydraulic fluid for consistent operation in temperature extremes, interior or exterior.

  • Fire and code: UL and cUL listed for fire doors, UL 10C positive-pressure listed. Meets ADA requirements in standard applications.

  • Arm interchangeability: Heavy-duty forged steel arms interchange across the Sargent 351, 1431, and 281 series.

  • Cover: High-impact non-corrosive plastic cover standard, metal and lead-lined optional. Optional MicroShield antimicrobial finish available.

  • Warranty: 30-year limited warranty.

 

Why specify the Sargent 351 closer

 

The 351 Powerglide is Sargent's heavy-duty answer for high-traffic openings, and it competes directly with the LCN 4040 class. The features that matter in daily use are the ones that resist abuse and tampering: front-facing valves you can adjust without removing the closer, captivated valves that won't get backed out and leak, adjustable backcheck to stop the door slamming into a wall, and all-weather fluid so the closing speed doesn't drift when the seasons change. The 30-year warranty tells you how Sargent rates the lifespan.

If you already run Sargent closers, the arm interchangeability across the 351, 1431, and 281 lines is a quiet advantage, because your existing arm inventory and your service techs' familiarity carry straight over.
