Sargent 281-O Tb En Surface Door Closer Standard Arm

Product Description

The SARGENT 281-O TB EN is a surface-mounted door closer designed for commercial and institutional door applications. It mounts on the face of the door or frame using a standard arm configuration and is secured with thru bolts for a robust, pull-resistant installation. The unit ships with a sprayed aluminum enamel finish, providing a clean appearance suited to standard commercial interiors. This closer is installed by commercial door hardware specialists, locksmiths, or licensed contractors working on access control and life-safety door assemblies.

The 281-O TB EN is intended for surface-mount applications on single-action swing doors in commercial buildings, schools, healthcare facilities, and institutional settings. The standard arm configuration positions the closer on the push side of the door, which is the most common installation orientation. Thru bolt mounting adds mechanical holding strength where pull-through resistance is a priority, such as high-traffic entryways.

Key Features

• Surface-mount design allows installation without door or frame preparation beyond bolt holes
• Standard arm configuration suits push-side mounting on the majority of commercial door swings
• Thru bolt fastening method increases resistance to fastener pull-through under heavy use
• Sprayed aluminum enamel finish blends with standard commercial door and frame finishes
• Designed for commercial-grade door applications including high-traffic entry points

Compatibility

Designed as an OEM-style surface door closer for commercial swing door assemblies where a standard arm, thru bolt mount configuration is required.

Installation Notes

Installation should be performed by a qualified door hardware technician or licensed contractor familiar with ANSI door closer standards and local building code requirements. Disengage any electric strike or access control power to the door assembly before beginning work. Thru bolt installations require clearance on both sides of the door or frame stile for nut tightening. Always verify door weight, width, and swing frequency against the closer model specifications before final installation.
