NGP 672DKB-36 – Frequently Asked Questions

1) Will the NGP 672DKB door sweep fit a 36 inch or 42 inch door?
The 672DKB brush sweep comes in two lengths, 36 inch and 42 inch. Pick the one that matches or exceeds your door width and cut it down to the leaf; the retainer is 6063 T5 aluminum, so it trims with a hacksaw or chop saw. Slotted screw holes let you shift the sweep up or down after mounting to set brush contact against the threshold.
2) Should I use a brush door sweep or a neoprene or vinyl blade sweep on a commercial door?
A brush seal like the 672DKB is the one to use where the floor is uneven, where the door drags carpet or tile transitions, or where you want the least drag on the closer. Nylon filament flexes over irregularities and springs back, and it holds up to abrasion better than a solid blade across a rough slab. A solid insert, like the neoprene on the Cal-Royal BTN-112, gives a tighter seal against air and water on a flat, true threshold, which is what you want for smoke or weather sealing. Brush for sweeping and light infiltration on rough floors, solid blade for a tight seal on good floors.
3) Is the NGP 672DKB certified to any BHMA standard for a spec job?
It is BHMA certified to ANSI/BHMA A156.22, the standard covering door gasketing and edge seals, and the certification covers the heat and cold performance tests. The materials are also REACH and RoHS compliant, which comes up on government and institutional submittals.
4) What is the closest equivalent to the NGP 672DKB brush door sweep from another manufacturer?
The Pemko 29326NB is the nearest match. It is a brush door bottom sweep with a concealed fastener design, the same two defining traits as the 672DKB: nylon brush sealing element and a snap-on cover that hides the screw heads. The Pemko is offered in a 36 inch length with a clear anodized aluminum finish, so if the opening needs to match dark bronze hardware the NGP 672DKB is the one that carries that finish, and it also comes in a 42 inch length for wider doors.
5) Does the NGP 672DKB come with mounting screws, or do I need to supply my own?
Screws are furnished. NGP includes #6 x 3/4 inch stainless steel sheet metal screws with the sweep, and the holes are slotted so you can set brush height before you tighten them down. Nothing else is required to hang it on a standard door face.
6) What does the concealed fastener design on the 672DKB actually do?
A snap-on cover clips over the retainer after installation and hides the screw heads. On a lobby or corridor door where the sweep is at eye level from the outside, that is the difference between a finished look and a row of exposed fasteners. Practically, it also means removing the cover is the first step any time you need to readjust the height or swap the brush.
7) Will a nylon brush sweep hold up in an unconditioned warehouse or a walk-in freezer door?
The nylon brush on the 672DKB carries a temperature range of -70 F to 425 F, so cold storage vestibules, boiler rooms, and unheated loading dock doors are all inside its range. It is also moisture resistant, which matters on a dock door that sees rain blow-in.
8) I have a run of doors to standardize. Can I order the 672DKB for 42 inch wide leaves too?
Yes. Both 36 inch and 42 inch lengths are offered in the dark bronze finish, so a mix of standard 36 inch leaves and wider 42 inch openings can be covered with the same model and finish. For anything under those widths, order the next length up and cut the aluminum retainer to size.
9) Is the Pemko 3452 rain drip a substitute for the NGP 672DKB door sweep?
No. The Pemko 3452 is a surface plate rain drip door bottom, which sheds water running down the face of the door away from the bottom edge. It does not do the job of the NGP 672DKB, which seals the gap between the door bottom and the floor with a nylon brush. On an exterior opening the two are often specified together rather than one in place of the other.
10) Which door bottom sweep should I standardize on across a facility that needs environmental and indoor air quality documentation?
Both directions are covered. The Pemko 345V carries a GREENGUARD Gold certified Eco-V insert, which is the one to cite when a project is chasing indoor air quality credits. The NGP 672DKB is BHMA certified to ANSI/BHMA A156.22 and is REACH and RoHS compliant, which is what a specification asking for material compliance and a tested gasketing performance standard is looking for. Pick by which document the spec on the job actually calls out.
11) I need a door sweep wider than 36 inches - what are my options?
The NGP 672DKB is made in a 42 inch length as well as 36 inch, so a 42 inch leaf is covered without cutting down from stock. Among brush and insert sweeps, the Pemko 29326NB and the Pemko 56 Series are each cataloged at 36 inches. Aluminum retainer sweeps are commonly cut to the door width on site, but if you want to order to length on a wide leaf, the 42 inch 672DKB is the direct answer.
12) Can I use the NGP 672DKB brush sweep for pest and rodent exclusion at the bottom of a door?
Yes, that is a common use. The nylon filament closes the gap at the floor and the material retains insecticides well, so it works with a treated program at the door line. Set the brush so it just contacts the threshold with the door closed, using the slotted holes, and keep in mind brush is a barrier against crawling pests and debris rather than an airtight seal.
13) Is the 672DKB rated for commercial traffic or is it a residential sweep?
Commercial. NGP builds it with a 6063 T5 aluminum retainer and a synthetic polyamide brush and certifies it to ANSI/BHMA A156.22, which is the spec institutional and MRO buyers standardize on across schools, hospitals, offices, and municipal buildings. It is not a hardware-store vinyl sweep.
14) If I do not need the concealed fastener cover, what is a simpler door sweep option?
The Cal-Royal BTN-112 is a straightforward extruded aluminum retainer with a neoprene insert, and the Pemko 56 Series is a door bottom sweep with an Eco-V insert offered in a 36 inch length. Both are exposed-fastener style retainers. The snap-on cover on the NGP 672DKB is what hides the screw heads, so it is the choice where the door bottom is visible in a finished lobby or corridor and the fastener line would show.

    What stands out is the concealed fastener design, which makes for a clean installation without visible screws, giving your door a much tidier appearance. The nylon brush sweep is effective at blocking drafts, dust, and insects, helping to maintain indoor comfort and potentially reduce energy costs.
