NGP 222SDKB-36 – Frequently Asked Questions

1) Will the NGP 222 automatic door bottom seal a gap under my door, and how big a gap can it close?
The 222 drops a maximum of 7/8 inch, so it will close a gap up to that under the door leaf. It works best over a threshold, which gives the seal a flat, hard surface to land on. Over bare carpet with no threshold, order the nylon brush seal instead of the sponge, since the sponge needs a solid surface to compress against.
2) Which side of the door does an NGP 222 automatic door bottom mount on?
Push side. The 222 is a surface applied unit, so it screws to the face of the door on the push side and the plunger trips against the stop as the door closes. That also means you need clear face space along the bottom rail on that side, not a mortised pocket.
3) Is the NGP 222 door bottom rated for a high traffic commercial opening?
It is certified BHMA Grade 1 to ANSI/BHMA A156.22, tested to 1,000,000 cycles. That is the top grade in that standard and it is the number to quote when a spec calls for a Grade 1 automatic door bottom on an office, school, or hospital opening.
4) Do I need an automatic door bottom, or will a door sweep do the job?
A sweep seals continuously; an automatic door bottom seals only when the door is shut and lifts clear as it opens. The Pemko 345 Series is a door bottom sweep with a PemkoPrene insert and an integral rain drip, which suits an exterior opening where you want to shed water down the face of the door. The NGP 222 drops up to 7/8 inch on closing and mounts on the push side, which is what you want over a finished floor or carpet where a dragging sweep would wear or bind. For an exterior door taking weather, the 345 sweep with the rain drip addresses the water; for a smoke, sound, or conditioned-space seal on an interior opening, the automatic bottom is the right form.
5) What is the closest equivalent to the NGP 222 automatic door bottom from another manufacturer?
The Pemko SA Series is the nearest cross-brand match. Both are automatic door bottoms that drop a seal when the door closes, and both mount to the face of the door rather than mortising into it. The Pemko SA3-36 carries a GREENGUARD Gold certified Eco-V insert; the NGP 222 uses a siloxane closed cell sponge seal rated from -100 F to 500 F and is BHMA Grade 1 certified to ANSI/BHMA A156.22 at 1,000,000 cycles. If the spec on the drawing calls out an ANSI/BHMA A156.22 Grade 1 automatic door bottom, the 222 is the one carrying that certification.
6) I need an automatic door bottom for a room protected by an FM200 clean agent system. Which one?
The NGP 222 is recommended for areas using FM200 or Halon fire suppression systems, with flame-resistant and moisture-resistant properties, and its siloxane closed cell sponge seal holds flexibility from -100 F to 500 F. The Pemko SA Series is also a surface mount automatic door bottom in the same form factor, carrying a GREENGUARD Gold certified Eco-V insert, which is the seal material to specify when the project is chasing indoor air quality credits instead. Match the seal material to which requirement is driving the opening.
7) Is the Pemko 345 a drop-in replacement for an NGP 222?
No. The Pemko 345 Series is a door bottom sweep, while the NGP 222 is an automatic door bottom. They are not the same part: the 222 carries an internal mechanism that drops a seal up to 7/8 inch when the door closes and retracts it when the door opens, and it is BHMA Grade 1 certified to ANSI/BHMA A156.22 with 1,000,000 cycle testing on that operation. The 345 has no drop mechanism to certify. If you are replacing a 222 and want equivalent operation, look at an automatic door bottom such as the Pemko SA Series rather than a sweep.
8) Will an automatic door bottom hold up in a boiler room or a freezer door application?
The 222's siloxane closed cell sponge seal stays flexible from -100 F to 500 F, and it carries BHMA heat and cold performance testing. It also resists ozone, UV, and aging, so exterior and mechanical space openings are within range. The housing is 6063 T5 aluminum alloy.
9) Can I use this door bottom in a room protected by FM200 or Halon?
Yes, the 222 is recommended for FM200 and Halon protected spaces. The seal is flame resistant and moisture resistant, which is what matters in a clean agent room, where the agent concentration depends on the enclosure holding tight.
10) What finishes does the NGP 222 automatic door bottom come in, and will it match my aluminum storefront doors?
Two finishes: anodized aluminum and dark bronze. Anodized aluminum matches clear anodized storefront framing; dark bronze matches dark bronze anodized. Both are offered in all three lengths, 36, 48, and 60 inches. End caps come with the unit, so there is nothing extra to order to finish the ends.
11) What is a good alternative to the NGP 222 automatic door bottom from another brand?
The Pemko SA Series is the closest cross brand match ZenSupply stocks, also a surface mount automatic door bottom, offered in 36 inch, with a GREENGUARD Gold certified Eco-V insert. If low emitting materials matter on a LEED or schools job, that insert is the differentiator. The 222 is the one to hold if you need the Grade 1 A156.22 certification called out on the drawing.
12) I need a rain drip on an exterior door bottom. Does the NGP 222 have one?
No, the 222 is an automatic door bottom, not a drip. If you need water thrown clear of the opening, the Pemko 345 Series door bottom sweep includes a rain drip along with its PemkoPrene insert. Some jobs run both, a door bottom for the seal and a separate drip cap above it.
13) There is no threshold under this door and it opens onto carpet. What should I use?
The NGP 222 has a nylon brush seal option intended for carpet applications without a threshold; the standard silicone seal is the one to run when you have a threshold to seal against. A door bottom sweep like the Pemko 345 Series is the wrong tool over carpet, since a fixed sweep stays down and drags on the pile every swing. Automatic bottoms, including the Pemko SA Series, lift on opening, which is why they are the family to look at for this opening.
14) We are standardizing door bottoms across a hospital. Which one holds up in high traffic?
The NGP 222 is BHMA Grade 1 certified to ANSI/BHMA A156.22 with 1,000,000 cycle testing, which is the durability figure to hand a facilities committee, and it is built with an aluminum alloy 6063 T5 temper housing. It is a commercial product and is used in healthcare institutions, educational facilities, and fire-rated door assemblies. Available in 36, 48, and 60 inch lengths in two finishes, one part number family covers most of a corridor standard. The Pemko SA Series is the comparable automatic door bottom if a project also has a GREENGUARD Gold requirement on the seal insert.
15) What is the NGP 222 door bottom seal actually made of, and will it take a cleaning chemical?
The seal is a synthetic rubber polymer, siloxane closed cell sponge, carried in a 6063 T5 aluminum alloy housing. Siloxane holds its memory and resists ozone, UV, and aging, which is why it keeps sealing on a door that cycles all day in a hospital or school corridor rather than taking a set and leaving a gap.
16) Is the NGP 222 automatic door bottom meant for residential doors?
It is a commercial product. The Grade 1 A156.22 certification and 1,000,000 cycle rating are aimed at office buildings, healthcare, education, and high traffic entrances. It will physically work on a house door, but you are paying for cycle life a residential opening never uses.
