Norton Rixson L27-180N-RH605 – Frequently Asked Questions

1) What is the Norton Rixson L27 180 Series floor closer designed for?
The L27 180 Series is a heavy-duty floor closer designed for doors that open 180 degrees. It features 3/4 offset design and lead lining for radiation shielding applications. This closer handles high-traffic commercial doors and specialized installations requiring maximum opening angles.
2) What door weights and sizes are compatible with this floor closer?
The L27 180 Series handles heavy commercial doors. Verify specific door weight and width requirements with manufacturer templates. The heavy-duty designation indicates capability for doors beyond standard commercial grades. Check door thickness compatibility with the 3/4 offset specification.
3) How does the 3/4 offset design affect installation?
The 3/4 offset allows the door to swing clear of adjacent walls or fixtures. This design provides additional clearance for 180-degree opening. Installation requires precise alignment with manufacturer templates to ensure proper offset positioning and smooth operation.
4) What applications require lead-lined floor closers?
Lead-lined closers are specified for radiation shielding applications. Common installations include medical facilities, laboratories, and industrial settings with X-ray or nuclear equipment. The lead lining prevents radiation penetration through the floor closer mechanism.
5) What are the power requirements for this heavy-duty closer?
Heavy-duty grade provides maximum closing force for large commercial doors. The L27 series offers adjustable closing and latching speeds. Power grade selection depends on door weight, frequency of use, and environmental conditions. Consult specifications for exact force ratings.
6) Does this closer meet accessibility and building code requirements?
Norton Rixson floor closers are designed to meet ADA and building code requirements when properly specified and adjusted. The 180-degree opening capability supports accessibility needs. Verify local code compliance and accessibility standards for your specific installation.
7) What components and accessories are included?
Floor closer includes the main body, top pivot, and mounting hardware. Templates and installation instructions are provided. Additional accessories may include different pivot styles or door shoes depending on application requirements. Verify complete package contents upon delivery.
8) What are the basic installation requirements?
Installation requires floor pocket excavation per manufacturer template. Concrete work must cure properly before closer installation. Precise alignment is critical for proper operation. Professional installation recommended due to specialized requirements of lead-lined units and 180-degree operation.
9) How do you adjust closing speed and force?
Adjustment screws control closing speed and latching action. Make small incremental changes and test operation. Adjustments should be made only by qualified personnel familiar with floor closer mechanisms. Over-adjustment can damage internal components or affect door operation.
10) What maintenance does this floor closer require?
Regular inspection of pivot points and adjustment settings. Keep floor pocket free of debris and moisture. Check door alignment and closing action periodically. Professional service recommended for internal maintenance due to lead lining and complex mechanism design.
11) Are there related models or alternatives in the Norton Rixson line?
Norton Rixson offers various L27 series configurations for different opening angles and offset requirements. Standard duty versions available for lighter door applications. Browse our door hardware section for comprehensive Norton Rixson floor closer options.
12) What field conditions affect floor closer performance?
Temperature extremes can affect hydraulic fluid viscosity and closing speed. High humidity or water exposure may cause corrosion. Wind pressure and building stack effect influence closing force requirements. Consider environmental conditions when specifying adjustment settings and maintenance schedules.
