Sargent 351-P9 Tb En Surface Door Closer Parallel Arm

Product Description

The SARGENT 351-P9 TB EN is a surface-mounted door closer designed for standard parallel arm installation. It mounts on the surface of the door or frame and uses a parallel arm configuration to control door swing and closing speed. Thru bolts are included for a secure, tamper-resistant fastening method. The sprayed aluminum enamel finish provides a clean, durable appearance suited to commercial and institutional door applications. This closer is installed by licensed carpenters, door hardware specialists, or commercial locksmith technicians during new construction or retrofit projects.

This door closer is appropriate for commercial, institutional, or light industrial door openings where a surface-mounted solution is preferred over a concealed or overhead installation. The parallel arm mount is commonly used when hinge-side clearance is limited or when the closer must be positioned on the stop side of the door. It is well suited for interior and exterior doors in office buildings, schools, healthcare facilities, and similar commercial environments requiring controlled latching and ADA-compliant closing cycles where the hardware meets applicable requirements.

Key Features

• Surface-mount design allows installation without routing or mortising into door or frame
• Standard parallel arm configuration suits stop-side mounting applications
• Thru bolt fastening provides added security and resistance to tampering or pull-out
• Sprayed aluminum enamel finish blends with standard commercial door hardware finishes
• Suitable for commercial and institutional door openings requiring consistent closing force

Compatibility

Designed as an OEM-style surface door closer for commercial and institutional door applications requiring a standard parallel arm, surface-mounted configuration with thru bolt installation.

Installation Notes

Installation should be performed by a qualified door hardware technician or commercial locksmith following the manufacturer's template and the applicable provisions of ANSI A156.4 for door closers. Power down any electrified hardware or access control devices connected to the door assembly before beginning work. Use the included thru bolts and follow the provided drilling template precisely to ensure proper arm geometry and closing performance. Adjust closing speed, latching speed, and backcheck valves only after the closer is fully mounted and the door is hanging correctly.
