Sargent 281-UO Tb En Surface Door Closer Universal Arm

Product Description

The SARGENT 281-UO TB EN is a surface-mounted door closer configured with a universal standard arm and secured using thru bolts. The unit ships in a sprayed aluminum enamel finish, providing corrosion resistance and a clean appearance suited to commercial and institutional environments. Surface door closers in this configuration are typically installed by commercial door hardware specialists or licensed contractors on standard hinged doors in high-traffic areas. The universal standard arm allows the closer to be mounted in multiple orientations, giving installers flexibility across a variety of door and frame configurations without sourcing additional hardware.

This door closer is intended for surface-mount applications on commercial, institutional, or light industrial doors. The thru-bolt fastening method provides a more secure mechanical connection than standard wood-screw mounting, making it appropriate for steel doors and frames or any application where pull-out resistance is a priority. It is a common fit for office buildings, schools, healthcare facilities, and government buildings where positive latching and controlled door swing speed are required by code or facility management policy.

Key Features

• Surface-mount installation keeps the mechanism accessible for adjustment and service without door disassembly
• Universal standard arm configuration supports multiple mounting orientations from a single unit
• Thru-bolt fastening method increases pull-out resistance on steel doors and hollow metal frames
• Sprayed aluminum enamel finish resists corrosion and blends with standard commercial door hardware finishes

Compatibility

Designed as an OEM-style surface door closer for standard commercial hinged door applications where a universal standard arm and thru-bolt mounting are specified.

Installation Notes

Installation should be performed by a qualified door hardware technician or licensed contractor familiar with commercial door hardware and applicable building codes. Verify door and frame material and thickness before drilling to ensure thru-bolt clearance. Close the door and confirm positive latching and sweep speed comply with ADA and local building code requirements after installation. Consult the closer arm adjustment instructions for sweep and latch speed valve settings before putting the door into service.
