Norton Rixson 93N-RH-689 – Frequently Asked Questions

1) What is the Norton Rixson 93 Series center hung system used for?
The 93 Series is designed for center hung single acting doors in commercial applications. It provides smooth operation for doors that swing in one direction from a centered pivot point. Common uses include office entries, retail spaces, and institutional buildings.
2) What door weights and sizes are compatible with this pivot system?
Verify specific weight and size limits with manufacturer specifications for your door dimensions. Center hung pivots typically handle substantial door weights but require proper sizing based on door height, width, and material. Always check the manufacturer template for compatibility.
3) How do I determine the correct handing for installation?
Handing is determined by standing on the side where the door swings away from you. Right hand if hinges are on the right, left hand if hinges are on the left. For center hung systems, specify the swing direction and any offset requirements during ordering.
4) What finishes are available for the dress cover plate?
Norton Rixson typically offers standard architectural finishes including satin chrome, polished brass, satin stainless steel, and bronze tones. The included dress cover plate provides a clean finished appearance. Verify available finishes for your specific model number.
5) What is the duty rating for commercial use?
Norton Rixson 93 Series pivots are engineered for heavy duty commercial applications. They meet industry standards for high frequency use in commercial buildings. Check specifications for cycle ratings and load capacities specific to your installation requirements.
6) Does this system meet accessibility and building code requirements?
Center hung pivot systems can meet ADA requirements when properly installed and adjusted. Verify local code compliance for your specific application. The system should provide smooth operation with appropriate opening force levels for accessibility standards.
7) What additional parts might be needed for installation?
Installation may require floor anchors, header reinforcement, and frame preparation hardware depending on your opening conditions. The dress cover plate is included. Review the manufacturer installation guide for complete hardware requirements and optional accessories.
8) What are the basic installation requirements?
Installation requires precise alignment of top and bottom pivot points. Floor must be level and structurally sound. Header requires adequate support for the pivot load. Follow manufacturer templates exactly for pivot placement and door preparation. Professional installation recommended.
9) How do I adjust the door alignment and closing speed?
Adjustment typically involves pivot alignment screws and integrated speed controls if equipped. Make small incremental adjustments to prevent over-correction. Door should hang plumb and operate smoothly. Consult installation instructions for specific adjustment procedures.
10) What maintenance does this pivot system require?
Regular maintenance includes cleaning pivot points, checking for wear, and lubricating moving parts per manufacturer schedule. Inspect mounting hardware for tightness. Address any operational issues promptly to prevent damage to door or frame components.
11) Are there related models or substitutes available?
Norton Rixson offers various pivot series for different applications. The 93 Series may have multiple configurations within the product line. For alternatives, browse our door hardware section or Norton Rixson products for comparable systems.
12) What field conditions affect performance?
Environmental factors include temperature changes, humidity, and building settling that can affect door alignment. High traffic areas require more frequent inspection. Ensure proper weatherproofing in exterior applications. Monitor door operation seasonally and adjust as needed.
