Sargent 351 HT Powerglide® Door Closer | Pull Side Hold Open Track Arm
The Sargent 351 HT Door Closer is the premier choice for architects and facility managers seeking a high-performance, low-profile door control solution. As part of the elite Powerglide® 351 Series, this model features a Pull Side Track Arm with Hold Open (HT). Unlike traditional projecting arms, the track system offers a clean, modern aesthetic while providing a variable hold-open function. This allows the door to be conveniently secured at a specific angle, making it ideal for high-traffic corridors, office suites, and healthcare patient rooms.
Built for longevity, the 351 HT is constructed from a heavy-duty one-piece die-cast aluminum silicon alloy with 14% silicon for superior wear resistance. This ANSI/BHMA Grade 1 closer is non-handed and features adjustable spring power from Size 1 to 6, ensuring it meets all ADA accessibility requirements while providing the strength required for fire-rated openings.
Elite Performance & Architectural Features
- Variable Hold Open Track: The HT track arm allows the door to be held open at a range of angles (typically 85° to 110°), perfect for moving equipment or high-frequency transitions.
- Sleek, Low-Profile Design: The track is mounted on the frame face (pull side), eliminating the "elbow" of a standard arm and reducing the footprint for a more professional appearance.
- Industrial Strength Piston: A massive 1-1/2" diameter piston provides the hydraulic power needed for superior door control and extreme durability over millions of cycles.
- All-Weather Reliability: Pre-filled with all-weather hydraulic fluid, the closer operates effectively in extreme heat or sub-zero cold without requiring seasonal valve adjustments.
- Tamper-Resistant Adjustments: Separate brass valves for closing speed, latching speed, and backcheck are controlled by an 1/8" Allen wrench and are captivated to prevent accidental removal.
- Fire & Safety Certified: UL/cUL listed for use on fire doors and conforms to UL10C and UBC positive pressure fire test standards.
