Norton Rixson 20NRH-605 – Frequently Asked Questions

1) What door weights and widths work with this Norton Rixson floor closer?
This standard duty closer handles doors up to 180 pounds and 48 inches wide. Verify your door dimensions and weight before ordering. Heavy doors may require heavy duty models.
2) How does the 20-3/4 offset hung configuration work?
The 20-3/4 offset places the pivot point away from the door face. This allows doors to swing fully open to 180 degrees maximum. Common for commercial entrances requiring wide opening clearance.
3) Can this closer work with both left and right hand doors?
Most Norton Rixson floor closers are field reversible for either hand. Check the installation template and adjust the pivot arm accordingly. Verify handing requirements during planning.
4) What floor preparation is needed for installation?
Requires floor pocket excavation per manufacturer template. Concrete floors need precise cutting and anchoring. Use the provided template for exact dimensions. Plan for proper drainage and weatherproofing.
5) Does this meet commercial building code requirements?
Norton Rixson closers typically meet ANSI standards for commercial use. Verify local code requirements for closing force and accessibility compliance. Some installations may need delayed action or reduced opening force.
6) How do you adjust closing speed and force?
Adjustment valves control closing speed and latching force. Use the provided adjustment tool to fine-tune operation. Make small incremental changes and test door operation between adjustments.
7) What finish options are available?
Standard finish is typically aluminum or painted steel. Some models offer bronze or stainless options. Check specific model availability for decorative finishes matching your hardware package.
8) Can this closer work in outdoor applications?
Floor closers handle weather exposure better than overhead units. Ensure proper floor pocket drainage and sealing. Consider temperature ranges and freeze protection for cold climates.
9) What replacement parts are commonly needed?
Pivot pins, adjustment screws, and seals wear over time. Stock common service parts for maintenance. Norton Rixson provides rebuild kits for major service intervals.
10) How does this compare to overhead door closers?
Floor closers hide mechanism below floor level for clean appearance. Better for heavy doors and extreme weather. Installation requires more floor prep but offers superior durability.
11) What door materials work best with floor closers?
Steel, aluminum, and solid wood doors perform well. Glass doors need proper reinforcement at pivot points. Avoid hollow core doors that cannot handle floor closer forces.
