Norton Rixson 8501-689 – Frequently Asked Questions
1) What door types work with the Norton Rixson 8501 series surface closer?
The 8501 series mounts on both interior and exterior doors. Compatible with wood, steel, aluminum, and composite doors. Verify door weight capacity matches closer grade. Check door thickness accommodates mounting screws.
2) How do I determine the correct handing for this closer?
Stand facing the door from the side where hinges are visible. If hinges appear on right, order right-hand. If hinges appear on left, order left-hand. Most 8501 models are handed-specific.
3) What finish options are available for the 8501 series?
Standard finishes include aluminum, bronze, and painted options. Cast aluminum body provides corrosion resistance. Verify specific finish availability with your model number. Factory finishes offer best durability.
4) What power grade is the Norton Rixson 8501 series?
Check model specifications for exact grade rating. Norton Rixson closers typically range from Grade 1 to Grade 3 per ANSI standards. Higher grades handle more door weight and cycles. Verify grade meets your application requirements.
5) Does this closer meet ADA compliance requirements?
Many 8501 models offer adjustable closing and latching speeds for ADA compliance. Opening force can be adjusted to meet 5 lbf maximum requirement. Verify specific model includes delay action feature if required by local codes.
6) What replacement parts are available for the 8501 series?
Common replacement parts include hydraulic fluid, seals, and adjustment valve assemblies. Arms and brackets available separately for damage replacement. Check with Norton Rixson door hardware for part availability by model number.
7) What tools are needed for installation?
Basic installation requires drill, drill bits, screwdriver, level, and measuring tape. Use manufacturer template for accurate hole placement. Pre-drill pilot holes in door and frame. Follow torque specifications for mounting screws.
8) How do I adjust closing speed on the 8501 series?
Locate adjustment valves on closer body. Turn clockwise to slow closing speed, counterclockwise to increase speed. Make small adjustments and test door operation. Separate valves typically control sweep and latch speeds.
9) What are similar models to the 8501 series?
Compare with other Norton Rixson surface closers in their product line. Consider Norton 1600 series or 7500 series for different applications. Check mounting requirements and grade ratings when substituting models.
10) Can this closer handle high wind load conditions?
Cast aluminum construction provides strength for moderate wind loads. Check closer grade rating against expected conditions. Consider hold-open arms or additional wind restraints for severe weather areas. Verify mounting strength on lightweight doors.
11) What are the key measurements needed before ordering?
Measure door width and height for sizing. Check door thickness for screw length. Measure frame clearance for closer body and arm swing. Verify hinge side clearance. Use manufacturer template to confirm fit before installation.
12) How often should the 8501 series be serviced?
Inspect operation monthly for proper closing speed and latching. Check mounting screws for tightness quarterly. Adjust speeds seasonally as temperature affects hydraulic fluid. Replace seals or fluid if leaking occurs. Heavy-use doors need more frequent checks.
