Kawneer KW050385 – Frequently Asked Questions

1) What size hinge is the Kawneer KW050385?
It is a 4-1/2 by 4 inch butt hinge package, meaning a 4-1/2 inch leaf height with a 4 inch open width. On a standard 1-3/4 inch commercial door the 4-1/2 inch height is the usual full mortise size, and the 4 inch width is the narrower option used where the door does not need extra clearance to swing past a deep frame or trim.
2) What does NRP mean on this Kawneer hinge, and do I need it?
NRP stands for non-removable pin. A set screw in the barrel sits behind the door leaf when the door is closed, so the hinge pin cannot be pulled and the door lifted off. You want it on any outswing door where the hinge barrels are exposed on the secure side, which covers most exterior commercial entrances and many stairwell and tenant doors. On an inswing door the barrels are already protected and NRP is optional.
3) Can I use this Kawneer hinge on a non-Kawneer door?
It is built to fit Kawneer commercial door assemblies and Kawneer exit device systems, so the safe application is a Kawneer opening. On another manufacturer's door it only works if that door already carries a 4-1/2 by 4 inch full mortise hinge prep with matching screw pattern. Pull the existing hinge and measure the leaf before committing.
4) What finish is the KW050385 hinge and will it match my other door hardware?
US32D satin stainless steel. That is the standard commercial finish on stainless exit devices, push plates and pulls, so it matches the brushed stainless look on most aluminum storefront and institutional openings. If the rest of the opening is US26D satin chrome the two read closely but are not identical materials.
5) Is the KW050385 a genuine Kawneer part or an aftermarket hinge?
It is a genuine Kawneer service replacement part, model KW050385, carried under Kawneer's service parts line. If you are maintaining a Kawneer aluminum entrance and need the hinge prep, pin and finish to match what came out of the door, this is the factory component rather than a generic substitute.
6) Is this hinge rated for high-traffic commercial use or is it a residential hinge?
Commercial. The KW050385 is classified as commercial door hardware, built for high-use openings such as office buildings, schools, healthcare facilities, retail and government buildings. It is not a light residential hinge.
7) Will satin stainless hold up on an exterior entrance door?
The US32D satin stainless finish is corrosion resistant, which is why it is the common choice on exterior commercial entrances and on openings in wet or wash-down areas. It also hides handling marks better than a polished finish on a door that gets used all day.
