NGP 222WHDKB-36 – Frequently Asked Questions

1) Will an automatic door bottom work over carpet if there's no threshold?
That's exactly what the nylon brush version is for. The NGP 222WH automatic door bottom uses a synthetic polyamide nylon brush seal, which NGP recommends for carpet applications where no threshold is provided. A solid vinyl or neoprene seal drags and wears on carpet pile; the brush sweeps over it. Drop capability is 7/8 inch maximum, so it can bridge the gap down to carpet height.
2) How is a brush automatic door bottom different from one with a vinyl or rubber insert?
A brush seal sweeps rather than wipes. It's the right call over carpet, uneven floors, or where a solid insert would bind, and it holds insecticide well if the opening is part of a pest control program. A solid insert seals tighter against smoke, light and drafts on a flat hard floor. Pemko's SA Series surface mount automatic door bottom is an example of the solid-insert approach, using a GREENGUARD Gold certified Eco-V insert in a 36 inch length.
3) Do I need an automatic door bottom like the NGP 222WH, or will a simpler door sweep do the job?
A fixed sweep such as the Pemko 345 Series is the simpler option - it mounts to the door face and drags a PemkoPrene insert continuously, with a rain drip for exterior openings. The NGP 222WH is a mechanical automatic door bottom that drops its nylon brush seal up to 7/8 inch only when the door closes and lifts it clear when the door swings, which is why it is the one specified over carpet where a fixed sweep would bind or wear. If the floor is hard and flat and you want the lowest-cost, fewest-moving-parts answer, the fixed sweep is it.
4) What is the closest equivalent to the NGP 222WH automatic door bottom from another manufacturer?
The Pemko SA Series, such as the SA3-36, is the nearest peer - it is a surface mount automatic door bottom in a 36 inch length, the same product function as the NGP 222WH. The difference is in the seal material and mounting style: the 222WH uses a synthetic polyamide nylon brush seal in an aluminum alloy 6063 T5 housing rated from -70 F to 425 F, while the Pemko SA3-36 carries a GREENGUARD Gold certified Eco-V insert. Choose the brush on carpeted openings with no threshold; choose a solid insert where you want a continuous contact seal against a flat sill.
5) Will this hold up in a boiler room or a freezer door?
The 222WH is rated from -70 F to 425 F. The extrusion is 6063 T5 temper aluminum alloy and the seal is synthetic polyamide, which keeps its flexibility and memory at both ends of that range and resists moisture. That covers cold storage vestibules through mechanical and boiler rooms.
6) Which door bottom should I use on an exterior opening that takes driving rain?
For an exterior door where water running down the face is the concern, the Pemko 345 Series sweep includes a rain drip that throws water clear of the bottom rail, which a brush-seal automatic bottom does not do. The NGP 222WH brush design is aimed at interior commercial openings - carpet with no threshold, and pest control work where the nylon holds insecticide - and it seals across a temperature range of -70 F to 425 F. On an exterior opening you can also run both: a drip sweep or drip cap outside and an automatic bottom for the closed-door seal.
7) My project spec calls for a low-emitting GREENGUARD certified seal - does the NGP 222WH meet that?
The NGP 222WH is built on REACH and RoHS compliant materials. If the specification specifically calls out GREENGUARD Gold, the Pemko SA Series automatic door bottom uses a GREENGUARD Gold certified Eco-V insert and is the direct swap in the same surface mount automatic door bottom function. Both are automatic door bottoms, so the opening prep and operating principle are the same - the certification and the seal material are what change.
8) Is the Pemko 345 sweep a drop-in replacement for an NGP 222WH?
No - they look similar on a cut sheet but they are different devices. The Pemko 345 is a fixed door bottom sweep; the NGP 222WH is an automatic door bottom whose seal retracts and drops up to 7/8 inch as the door operates. Swapping a 345 in where a 222WH was specified means the seal rides the floor at all times, which changes door pull effort and wear, particularly over carpet. Match automatic to automatic - the Pemko SA Series is the automatic-function peer.
9) Is this rated for commercial traffic or is it a residential part?
Commercial. NGP builds the 222WH for office buildings, schools, healthcare, retail, warehouses, multi-tenant residential and government facilities, with a 6063 T5 aluminum housing rather than a light residential extrusion. REACH and RoHS compliant materials, which matters on institutional and government specs.
