NGP D608B-28 – Frequently Asked Questions

1) Will the NGP D608B brush sweep fit a standard 36 inch door?
No. The D608B nylon brush sweep comes in 28 inch and 30 inch lengths only, so it will not span a 36 inch door leaf. For a 36 inch opening, look at the Pemko 29326NB brush door bottom sweep, which is a 36 inch brush sweep with clear anodized aluminum and a concealed fastener design. Sweeps are commonly cut down to fit, but they cannot be extended.
2) Can I use the NGP D608B on a smoke rated door assembly?
The D608B is a Category H Smoke and Draft Control door sweep, which is the classification used for smoke and draft control door bottom sealing. That is what a code inspector is looking for on a smoke barrier opening.
3) What is the closest brush door sweep equivalent to the NGP D608B from another manufacturer?
The Pemko 29326NB is the nearest brush-type match. Both are brush door bottom sweeps on an aluminum frame; the NGP D608B uses a 1 inch nylon brush in an aluminum alloy 6063, T5 temper frame with a gold finish, while the Pemko 29326NB is a 36 inch brush door bottom sweep in clear anodized aluminum with a concealed fastener design. Choose on frame appearance and fastener exposure: the D608B mounts with exposed slotted screw holes and comes in 28 inch and 30 inch lengths, so it suits narrower openings, whereas the 29326NB arrives at 36 inch and hides its fasteners.
4) Should I use a brush sweep or a neoprene insert sweep on a commercial door bottom?
A brush sweep such as the NGP D608B seals across uneven thresholds and rough floors because the synthetic polyamide brush flexes and returns to shape, and it holds up from -70 F to 425 F. A blade-style option is the Cal-Royal BTN-112, an extruded aluminum retainer with a neoprene insert, which presents a continuous solid seal instead of bristles. Use the brush where the floor is irregular or debris and pests are a concern; use the neoprene insert where you want a solid wiping seal against a flat, even floor.
5) Is there a door sweep with a low-emission or green-certified seal instead of the NGP D608B nylon brush?
Yes. The Pemko 345V door bottom sweep uses a GREENGUARD Gold certified Eco-V insert, and the Pemko 56 Series door bottom sweep also carries an Eco-V insert in a 36 inch length. The NGP D608B instead uses a 1 inch synthetic polyamide brush and is REACH and RoHS compliant. If a project is chasing indoor-air-quality credits on the gasketing itself, the Eco-V inserts are the ones specified by that certification; if the requirement is REACH and RoHS material compliance with a brush seal, the D608B answers it.
6) I need a sweep for a 36 inch door - what are my options if the NGP D608B does not come long enough?
The NGP D608B is offered in 28 inch and 30 inch lengths. For a nominal 36 inch leaf, the Pemko 29326NB is a 36 inch brush door bottom sweep in clear anodized aluminum with concealed fasteners, and the Pemko 56 Series door bottom sweep is also supplied at 36 inch with an Eco-V insert. Pick the 29326NB to stay with a brush seal like the D608B, or the 56 Series if a blade-type insert suits the floor.
7) For a smoke and draft control opening, which sweep should I specify?
The NGP D608B is a Category H Smoke and Draft Control compliant door sweep, which is the designation an inspector looks for on a smoke barrier opening. Among brush and insert alternatives, the Pemko 29326NB and Pemko 345V are catalogued by their function as door bottom sweeps, and the Cal-Royal BTN-112 belongs to the Brush Weatherstrips Series. If the drawing calls out smoke and draft control at the door bottom, the D608B carries that Category H compliance directly.
8) Do I need to buy screws separately for this NGP door sweep?
No. The D608B ships with #6 x 3/4 inch stainless steel sheet metal screws. The mounting holes in the aluminum frame are slotted, so you can shift the sweep up or down to set brush contact on the floor before you tighten them down.
9) Will this NGP sweep hold up on a walk-in freezer door or a boiler room door?
Yes. The D608B is rated from -70 F to 425 F, which covers both cold storage and high-heat mechanical spaces. The frame is 6063 aluminum in T5 temper and the brush is synthetic polyamide, so neither material is the limiting factor across that range.
10) Will the Pemko 3452 work in place of the NGP D608B nylon brush sweep?
Not as a direct swap. The Pemko 3452 is a surface plate rain drip door bottom, so its job is to throw water off the face of the door and away from the bottom edge. The NGP D608B is the seal itself, a 1 inch nylon brush in an aluminum frame rated for Category H Smoke and Draft Control. On an exterior opening the two are often used together rather than one instead of the other: the rain drip above, the brush sweep sealing the gap at the floor.
11) What does the gold finish on the D608B look like next to my existing aluminum sweeps?
The D608B frame is gold anodized aluminum with a black brush, so it reads warm rather than silver. If the rest of your openings run clear aluminum, it will not match, and the Pemko 29326NB brush sweep is a clear anodized option. Aluminum also gives corrosion resistance on exterior and damp openings.
12) Is the NGP D608B brush sweep meant for commercial doors or houses?
It is a commercial-duty sweep. NGP lists the D608B for office buildings, schools, healthcare, retail, industrial and warehouse space, multi-tenant residential and government buildings. You can certainly hang one on a residential door, but the 6063-T5 frame and polyamide brush are specified for traffic well beyond that.
13) Does this door sweep meet REACH and RoHS for our institutional purchasing spec?
The D608B is built from REACH and RoHS compliant materials, which covers most institutional and government environmental purchasing requirements for hardware of this type.
14) Will a brush sweep help with pests under the door?
The polyamide filament on the D608B resists moisture and retains insecticides, so it is used where pest control is part of the job. The brush also closes down over minor floor irregularities that a rigid insert would bridge, which is usually where the gap is.
