Norton Rixson 91NDCP-RH-689 – Frequently Asked Questions

1) What is the Norton Rixson 91DCP series door closer designed for?
The Norton Rixson 91DCP is an offset hung single acting overhead concealed door closer. It's designed for interior doors where you want the closer mechanism hidden above the frame. Works with single swing doors that need controlled closing action.
2) What door sizes and weights does this closer handle?
Check the manufacturer's specifications for exact capacity ratings. Most Norton Rixson overhead concealed closers handle standard commercial door sizes. Verify your specific door width, height, and weight against the product template before ordering.
3) How do I determine the correct door handing for installation?
Stand on the pull side of the door. If hinges are on your right, it's right hand. If hinges are on your left, it's left hand. The 91DCP series may require specific handing based on the offset hung design. Confirm handing requirements with the installation template.
4) What finishes are available for the dress cover plate?
The dress cover plate typically comes in standard architectural finishes to match other door hardware. Common options include aluminum, bronze, and painted finishes. Check the specific model specifications for available finish options.
5) What power rating does this door closer provide?
Norton Rixson overhead concealed closers typically provide medium to heavy duty closing power. The exact power rating varies by model within the 91DCP series. Refer to the product specifications to ensure it meets your door's requirements and local code compliance.
6) Does this closer meet ADA and building code requirements?
Norton Rixson closers are typically designed to meet ADA opening force requirements when properly adjusted. However, always verify local building codes and ADA compliance for your specific application. Some installations may require additional considerations for accessibility.
7) What installation requirements should I know about?
Overhead concealed closers require adequate clearance above the door frame for the closer body. You'll need to cut precise openings in both the door and frame. Follow the manufacturer's template exactly. Professional installation is recommended due to the precision cutting required.
8) Are replacement parts available for the 91DCP series?
Norton Rixson typically provides replacement parts for their commercial door closers. Common replacement items include arms, springs, and adjustment components. Contact the manufacturer or check with door hardware specialists for specific part availability.
9) How do I adjust the closing speed and latching action?
Most Norton Rixson closers have adjustment valves for closing speed and latching speed control. These are typically accessed through small adjustment screws. Make small incremental adjustments and test the door operation. Refer to the installation instructions for valve locations.
10) What other Norton Rixson door closer models are available?
Norton Rixson offers various overhead concealed closer models for different applications. Options include different power ratings, mounting configurations, and special features. Browse our Norton Rixson collection for alternative models that might suit your project needs.
11) Can this closer work in high-traffic commercial applications?
Norton Rixson commercial grade closers are designed for institutional and commercial use. The 91DCP series should handle regular commercial traffic when properly sized for the door. Consider cycle life ratings and maintenance requirements for high-traffic installations.
12) What field conditions affect closer performance?
Temperature extremes can affect hydraulic fluid viscosity and closer performance. Drafty conditions may require stronger closing power. Door alignment and hinge condition also impact closer operation. Ensure proper door fit and hardware alignment before installation.
