Sargent 351 HTB Powerglide® Door Closer | Pull Side Hold Open Track Arm with Bumper
The Sargent 351 HTB Door Closer is an elite, high-traffic door control solution that combines a sleek architectural profile with heavy-duty durability. As a specialized model in the Powerglide® 351 Series, the 351 HTB features a Pull Side Hold Open Track Arm equipped with an integrated Track Bumper. This design is ideal for modern commercial interiors where a low-profile aesthetic is required, providing both the convenience of a variable hold-open and a cushioned bumper to assist the hydraulic backcheck.
Forged from a specialized 14% silicon aluminum alloy, the one-piece die-cast body is engineered to exceed 25 million cycles. The heat-treated full closed rack and pinion ensures total control from the full open position. With adjustable spring power from Size 1 to 6, this non-handed closer is a versatile "one-box" solution that meets ADA accessibility requirements while providing the robust force needed for fire-rated doors.
Advanced Architectural Features & Performance
- Integrated Track Bumper: The HTB track includes a specialized bumper that mounts within the extruded aluminum track to assist the backcheck, protecting the door and hardware from damage during forceful opening cycles.
- Variable Hold Open Function: The forged steel arm works with an adjustable holder mounted within the track, allowing the door to be secured in an open position for deliveries or high-frequency transition periods.
- Precision Hydraulic Regulation: Features separate, low-sensitivity brass valves for independent regulation of closing speed, latching speed, and backcheck intensity.
- All-Weather Reliability: Pre-filled with all-weather hydraulic fluid, ensuring the closer operates effectively in extreme temperatures without the need for seasonal valve adjustments.
- Vandal Resistant: All adjustment valves are controlled by an 1/8" Allen wrench and are captivated within the body to prevent accidental removal or tampering.
