NGP 672A-36 – Frequently Asked Questions

1) Is the NGP 672A door sweep BHMA certified for a commercial building spec?
Yes. The 672A is BHMA certified to ANSI/BHMA A156.22, specifically the heat and cold resistance performance tests. That is the gasketing and edge seal standard, and it is what a spec writer or a facilities buyer standardizing across a campus will be looking for on the submittal.
2) Will a nylon brush door sweep hold up in a freezer entry or a boiler room?
The 672A is rated from -70 F to 425 F, which covers cold storage vestibules, unconditioned loading docks and mechanical rooms at the hot end. The frame is 6063 T5 temper aluminum alloy, anodized, and the brush is synthetic polyamide nylon, so neither element is the weak link across that range.
3) Should I use a brush sweep or a neoprene sweep on a commercial door bottom?
It comes down to what the sweep has to ride over. The NGP 672A uses a synthetic polyamide nylon brush in an aluminum alloy 6063 T5 body, and the brush filaments flex over carpet, thresholds, floor transitions and uneven slabs without dragging or deforming, which is why the brush style is the common pick on interior corridor and stairwell doors where the floor is not perfectly flat. The Cal-Royal BTN-112 takes the other approach: an extruded aluminum retainer with a neoprene insert. A solid neoprene blade wipes a continuous line against a flat, level floor and closes the gap more completely than filaments do, so it suits smooth sealed concrete or tile where you want a tighter contact seal. Also worth knowing on the 672A side: the nylon brush is rated for a temperature range of -70 F to 425 F and the sweep is BHMA certified to ANSI/BHMA A156.22 for heat and cold resistance, which matters on mechanical rooms, boiler rooms and exterior service doors.
4) I need a door bottom that handles rain and runoff on an exterior opening. Is the NGP 672A the right part?
For a swinging exterior door taking direct weather, the Pemko 3452 is the part built for that job. It is a surface plate rain drip door bottom, meaning it combines the door bottom seal with a drip that throws water clear of the door edge instead of letting it run down the face and into the gap. The NGP 672A is a nylon brush sweep in an anodized aluminum body with a snap-on cover over the fasteners. Its strength is a flexible filament seal that rides over uneven floors and holds up across -70 F to 425 F, and it is BHMA certified to ANSI/BHMA A156.22 for heat and cold resistance. Brush filaments block air movement, light, smoke path and pests well but do not shed standing water the way a drip profile does. On an exterior door with an overhang or a recessed entry, the 672A is often still the correct sweep; on a fully exposed opening taking wind-driven rain, specify the rain drip style.
5) Our project has a low-emitting materials requirement. Does the NGP 672A meet it, or do I need a different sweep?
If the specification calls for a third-party low-emissions certification on the sealing material itself, the Pemko 345V is the one written for it: it is a door bottom sweep with a GREENGUARD Gold certified Eco-V insert, and the Pemko 56 Series carries the same Eco-V insert in a 36 inch length. The NGP 672A answers a different compliance question. Its nylon brush construction meets REACH and RoHS compliance standards, and the sweep is BHMA certified to ANSI/BHMA A156.22 for heat and cold resistance performance. REACH and RoHS speak to restricted substances in the material; GREENGUARD Gold speaks to indoor air emissions. If the drawing cites a chemical-content restriction, the 672A answers it. If it cites indoor air quality credits, specify the Eco-V insert product.
6) Will the screws show after installing the NGP 672A door sweep?
No. The 672A carries a snap-on cover that hides the screw heads once the sweep is fastened, so the face of the sweep reads clean from the corridor side. That matters on lobby and tenant-facing doors where a row of exposed pan heads looks like a repair rather than a finished install.
7) Can I adjust the height of the NGP 672A after mounting it?
The mounting holes are slotted, so you can slide the sweep up or down to set brush contact before you tighten down. Set it so the brush just kisses the floor through the swing, not so it compresses hard, or the door will feel heavy and the brush will wear early. Fasteners are included: #6 x 3/4 inch stainless steel sheet metal screws.
8) Is the NGP 672A a direct swap for a Pemko brush sweep I already have on the building?
Both are brush-type bottom sweeps in clear anodized aluminum with concealed fasteners, so visually they read the same across a run of doors: the Pemko 29326NB is the closest brush-and-concealed-fastener counterpart we carry. What we hold on the Pemko does not include its section dimensions, so treat it as a like-for-like look rather than a confirmed hole-pattern match. If you are replacing a whole floor of sweeps, standardize on one part rather than mixing, since brush height and cover profile differ between makers.
9) Will a door sweep alone stop rain from getting under an exterior door?
A brush sweep like the 672A handles air, light, dust and insects at the door bottom, but bristles do not shed water the way a solid lip does. For a driving-rain exterior opening, a rain drip is the companion piece, and the Pemko 3452 surface plate rain drip door bottom is the type to look at. Many exterior installs use both: drip above to throw water clear, sweep below to close the gap.
10) Is there a simpler door sweep than the NGP 672A if I do not care about hiding the screws?
Yes. The concealed fastener design is a large part of what the NGP 672A is: a snap-on cover hides the screw heads for a finished appearance, and slotted screw holes under that cover let you fine-tune the height against the floor before the cover goes on. If appearance is not driving the job, the Pemko 56 Series door bottom sweep with Eco-V insert in a 36 inch length is a more basic surface-applied door bottom, and the Cal-Royal BTN-112 pairs an extruded aluminum retainer with a neoprene insert in a straightforward two-piece assembly. Both are door bottom sweeps that mount to the face of the door in the same general way. Where the 672A earns the extra step is on doors people look at: lobby, corridor and tenant entry doors in offices, schools, healthcare facilities and multi-tenant residential buildings, where exposed fastener heads across the bottom rail read as unfinished.
11) What door bottom parts look like a substitute for the NGP 672A but will not actually replace it?
Two to watch. The Pemko 3452 is a surface plate rain drip door bottom, and although it is a door bottom part, the drip profile projects out from the door face to shed water and is not a drop-in for a plain brush sweep; on an interior door it adds a protruding edge with no benefit. The Cal-Royal BTN-112 is the other one, because it sits in the Brush Weatherstrips Series and reads as a brush product in a catalog listing, but the part itself is an extruded aluminum retainer with a neoprene insert, which is a solid blade seal rather than filaments. If you are replacing a worn 672A and the floor has carpet, a transition strip or an out-of-level slab, that swap will bind or scrape. A true like-for-like on brush, anodized aluminum body, and concealed fasteners is the Pemko 29326NB in 36 inch.
12) Is the NGP 672A sweep OK for a hospital or school where chemical cleaners get used on the floors?
The 672A is built for that duty. The construction is moisture resistant, it retains insecticides well, and the materials meet REACH and RoHS compliance. NGP lists healthcare institutions and educational facilities among the applications for this sweep, alongside offices, retail, industrial, multi-tenant residential and government buildings.
13) Is the NGP 672A rated for commercial use or is it a residential sweep?
Commercial. The 672A is a commercial-grade door bottom sweep, and it is built like one: extruded 6063 T5 aluminum frame rather than a formed strip, BHMA certification to ANSI/BHMA A156.22, and a nylon brush chosen for abrasion resistance under traffic. It works fine on an apartment corridor door, but it is specified for openings that cycle all day.
