Norton Closers CLP8501689 Surface Mount Door Closer

Product Description

The NORTON CLOSERS CLP8501689 is a CloserPlus surface mount door closer with an adjustable arm, sex nuts, and a full cover in an aluminum finish. It uses a rack and pinion hydraulic mechanism with valve-controlled backcheck to manage door swing speed and closing force. The aluminum alloy body keeps weight down while maintaining durability. This closer is a non-handed design, meaning it installs on left- or right-hand doors without requiring separate units. Licensed HVAC and door hardware contractors, locksmiths, and general contractors install this type of closer in commercial and light-commercial entryways where controlled door closing is required.

The CLP8501689 is suited for surface mount applications on standard door frames in commercial buildings, institutional facilities, and light-commercial construction. The adjustable arm allows the installer to tune the closing geometry to the door width and frame conditions on site. The included sex nuts provide secure through-door fastening where standard wood screws are insufficient. The full cover conceals the closer body and arm hardware for a cleaner appearance in finished entryways.

• Rack and pinion hydraulic mechanism for consistent, controlled closing force

Compatibility

Designed as an OEM-style surface mount door closer for standard commercial door and frame applications where a rack and pinion hydraulic closer with adjustable arm is specified.

Installation Notes

Installation is typically performed by a licensed locksmith, door hardware technician, or general contractor. Power down any access control hardware connected to the door before beginning. Follow the template provided with the closer for accurate fastener placement, and use the sex nuts for through-door mounting on hollow metal doors where pull-through force is a concern. Adjust the sweep, latch, and backcheck valves with a hex key after mounting to achieve the desired closing speed and check action per the door manufacturer and ADA requirements.
