NGP H612DKB-48 – Frequently Asked Questions

1) Will the NGP H612A brush sweep work on a 36 inch wide door?
The H612A comes in a 48 inch length, so on a 36 inch door you cut it down on site. Aluminum 6063 T5 base cuts cleanly with a hacksaw or miter saw, and the nylon brush trims with it. If you would rather not cut, the Pemko 29326NB is a brush bottom sweep supplied at 36 inches, and the Pemko 56 Series bottom sweep also comes 36 inches long.
2) Is the NGP H612A door sweep rated for smoke and draft control?
Category H smoke and draft control, which is what the H612A is built for on commercial openings. That is the reason it shows up on corridor and cross-corridor doors in schools and hospitals rather than a plain weather sweep.
3) How much gap will a 2-1/2 inch NGP brush sweep close under a door?
The brush on the H612A is 2-1/2 inches of nylon bristle off the aluminum base, so it covers a large undercut and still makes contact where the floor is not level. Slotted screw holes in the base let you set the height so the bristle just sweeps the floor without loading the door closer.
4) Is the NGP H612A a rain drip or does it stop water at an exterior door?
Not a rain drip. The H612A is a surface-applied brush sweep that mounts to the door face and seals the undercut against smoke, draft and debris; brush bristle is not a water barrier. To shed rain away from the bottom of an exterior door you want a drip-style bottom such as the Pemko 3452 surface plate rain drip door bottom, which is a separate part and can be used along with a sweep.
5) Should I use a brush sweep or a neoprene insert sweep on a commercial door?
It depends on how the door bottom meets the floor. A brush sweep like the NGP H612A uses a 2-1/2" synthetic polyamide nylon brush that flexes over carpet, uneven slab, and floor transitions while keeping its memory, and it holds up across a temperature range of -70 F to 425 F. A solid insert sweep such as the Cal-Royal BTN-112, which carries a neoprene insert in an extruded aluminum retainer, wipes a flat consistent surface and gives a continuous line of contact rather than filament contact. Brush is the usual choice where the sweep has to ride over an irregular or carpeted floor; a neoprene insert is the usual choice where the floor under the door is flat and smooth.
6) What is the closest brush door sweep to the NGP H612A from another manufacturer?
The Pemko 29326NB is the nearest brush-type equivalent. Like the H612A, it is a brush door bottom sweep on a clear anodized aluminum base, so the sealing action is the same flexible filament contact against the threshold rather than a solid wiper. The two differ in fastening approach: the Pemko 29326NB uses a concealed fastener design, while the H612A mounts through slotted screw holes with #6 x 3/4" stainless steel sheet metal screws furnished. The Pemko 29326NB is a 36" piece, so on a 48" opening the NGP H612A covers the leaf in one length while the 36" Pemko would need to be ordered in a length that suits the door.
7) What do I use instead of a brush sweep on an exterior door that gets driving rain?
Look at a rain drip type door bottom such as the Pemko 3452, which is a surface plate rain drip door bottom. That design adds a projecting drip that throws water clear of the door bottom, which a brush sweep does not do. The NGP H612A is built around smoke and draft control, with a 2-1/2" nylon brush and Category H smoke and draft control performance, so it is aimed at controlling air and smoke movement at the door bottom rather than shedding water off an exposed exterior face. On an exterior opening that takes weather directly, the rain drip style and a bottom seal are often used together.
8) Do I need to buy screws with the NGP H612A sweep?
No extra fasteners needed. #6 x 3/4 inch stainless steel sheet metal screws come with the H612A. You will want a drill and, if you are shortening the piece from 48 inches, a saw.
9) What finishes does the NGP H612A 48 inch brush sweep come in?
Two anodized aluminum finishes, mill aluminum and dark bronze, both on the 48 inch length. Mill matches clear anodized aluminum frames and doors; dark bronze matches dark anodized storefront and bronze-finish openings.
10) Can a brush door sweep handle a boiler room or freezer door?
The H612A holds up from -70 F to 425 F, so cold storage vestibules, mechanical and boiler rooms are inside its range. The 6063 T5 aluminum base is anodized for corrosion resistance, and the polyamide bristle resists moisture, which matters in wash-down and damp mechanical spaces.
11) Which door sweep should I specify on a project that requires certified low-emitting materials?
The Pemko 345V is the one in this class carrying a GREENGUARD Gold certified Eco-V insert, which is the attribute a project team is usually chasing when the specification calls for certified low-emitting interior materials. The NGP H612A carries a different set of compliance credentials: it is REACH and RoHS compliant and meets Category H smoke and draft control requirements, which is what a life-safety or smoke-partition line item asks for. If the drawing calls for both, they are answering two separate spec sections, not competing on the same one.
12) Is the Pemko 56 Series a drop-in replacement for an NGP H612A brush sweep?
Not a like-for-like swap on the sealing element. The Pemko 56 Series door bottom sweep uses an Eco-V insert, which is a solid insert seal, while the NGP H612A seals with a 2-1/2" synthetic polyamide nylon brush on an aluminum alloy 6063 T5 temper base. Swapping one for the other changes how the door bottom contacts the floor, so the floor condition and the required gap should be rechecked rather than assumed. Length also differs in what is offered: the Pemko 56 Series is a 36" piece, and the NGP H612A comes in 48" in mill aluminum and dark bronze.
13) I need a brush sweep but the fasteners have to be hidden. What are my options?
The Pemko 29326NB is the brush door bottom sweep built around a concealed fastener design, so the mounting screws are not visible on the face of the sweep once it is installed. The NGP H612A mounts through slotted screw holes on the anodized aluminum base, which leaves the fastener heads exposed but lets the sweep be shifted up or down for exact height alignment to the floor before the screws are set. On a finish-sensitive door face the concealed design is the one to reach for; where the floor is out of level and the sweep height needs fine adjustment, the slotted holes on the H612A are the practical advantage.
14) Can I standardize the same NGP brush sweep across all the doors in my building?
Yes, and that is the usual way it gets bought. One 48 inch H612A covers standard commercial door widths with no joint, and it is cut down for narrower leaves, so a single part number handles most of a fleet. Order mill aluminum or dark bronze to match the frames on each wing.
15) Are NGP door sweeps REACH and RoHS compliant for a government or healthcare spec?
The H612A uses REACH and RoHS compliant materials, which covers the substance-restriction line item that shows up on institutional and government submittals. If the spec also calls for a low-emitting certified product, the Pemko 345V carries a GREENGUARD Gold certified Eco-V insert.
16) Does the NGP H612A mount with exposed screws?
Yes, it fastens through slotted holes in the aluminum base on the face of the door, so the fastener heads are visible along the base. If concealed fasteners are required for the look, the Pemko 29326NB is a brush bottom sweep with a concealed fastener design in clear anodized aluminum.
