NGP 220NA 36 LH – Frequently Asked Questions

1) Do I have to specify handing on an NGP 220N door bottom?
Yes, handing is an order choice. The 220N is sold left handed and right handed, and the actuator plunger sits at the hinge end, so the hand has to match the door it is going on. Stand outside the door: if the hinges are on your left it is left handed. Ordering the wrong hand puts the plunger against the lock stile where nothing trips it.
2) Is the NGP 220N rated for a high traffic commercial door?
It carries BHMA Grade 1 certification to ANSI/BHMA A156.22 with a 1,000,000 cycle test rating, which is the top durability tier in that standard. That is the rating you want on a school corridor, a hospital door, or a main office entry that swings all day. It is a commercial product, not a residential one.
3) Will an automatic door bottom hold up on an exterior door in freezing or hot weather?
The 220N is BHMA certified for both heat and cold performance tests and operates from -20 F to 200 F. The aluminum is 6063 T5 with an anodized finish for corrosion resistance, and the seal material resists ozone, sunlight, moisture, and aging. That covers exterior openings in most climates.
4) Should I use an automatic door bottom or just a door sweep?
An automatic door bottom like the 220N retracts when the door opens and drops only when it closes, so nothing drags on carpet or an uneven floor and the seal is not worn down by every swing. A fixed sweep such as the Pemko 345 Series rides on the floor at all times, which is simpler and fine over a smooth threshold but wears faster and can bind on flooring transitions. Choose the automatic bottom where the floor changes height, where the door sees heavy traffic, or where you need a tighter seal for sound and air.
5) What is the difference between the NGP 220N and the Pemko SA Series automatic door bottom?
Both are automatic door bottoms. The Pemko SA Series is a surface mount unit with a GREENGUARD Gold certified Eco-V insert, which is the one to look at if you are chasing indoor air quality credits or cannot mortise the door. The NGP 220N uses a neoprene seal, a synthetic rubber blend of PVC, nitrile, and chloroprene closed cell foam, and is Grade 1 certified at 1,000,000 cycles. Pick on mounting method and seal material rather than on capability.
6) Can I get an NGP 220N with lead lining for an X-ray or imaging room?
A 1/16 inch thick lead insert is available as an option on the 220N for added sound attenuation. It is an ordering option, so it has to be specified when the unit is bought, not added later.
7) What finish does the NGP 220N automatic door bottom come in?
Anodized aluminum, and that is the only finish offered. On a 36 inch unit it comes that way in both left and right hand. Anodizing on the 6063 T5 housing is what gives the corrosion resistance, so if you are standardizing door bottoms across a building the appearance will match opening to opening.
8) Will an NGP 220N help with sound transfer between a corridor and an office?
Sealing the gap under the door is the biggest single improvement you can make to a door's sound performance, and the 220N closes up to 7/8 inch of it with a closed cell elastomeric foam seal. For a room needing more, the optional 1/16 inch lead insert adds attenuation. Pair it with head and jamb gasketing to get the full benefit; the door bottom alone leaves the perimeter open.
