NGP H623A-42 – Frequently Asked Questions

1) Can I use the NGP H623A brush door sweep on a fire rated door?
Yes. The H623A brush sweep is approved for fire rated metal doors up to 3 hours and wood doors up to 60 minutes, so it can go on a labeled opening in a school, hospital, or office corridor without breaking the door's rating.
2) What length door sweep do I need for a standard 36 inch door, and does NGP make one long enough for a pair?
The H623A comes in 42 inch and 84 inch lengths. The 42 inch covers a standard 36 inch single leaf with room to trim the aluminum housing down to the door width. The 84 inch length covers a pair of 42 inch leaves, or you cut it into two pieces for two openings.
3) How much gap under the door will a 2-1/2 inch brush sweep close?
The brush stands 2-1/2 inches tall and sits at a 45 degree angle, so it reaches down and across rather than straight down. That angle is what lets a brush sweep cover an uneven or oversized undercut that a rigid vinyl or neoprene sweep would skip over. The housing mounts to the face of the door with slotted holes, so you set the brush height to the actual gap you have at the sill rather than to a nominal number.
4) Should I use a brush sweep or a vinyl sweep on an exterior door?
Brush is the choice when the sill is rough, uneven, or you drag over a threshold, carpet, or a floor that is not flat. The polyamide filament flexes over the obstruction and springs back instead of tearing or curling like a vinyl blade. Vinyl or a channel gasket seals tighter against a flat, clean surface and is the better pick for a smooth aluminum threshold; ZenSupply carries the Cal-Royal PG-601 aluminum channel gasketing with a vinyl insert for that. Brush also handles temperature swings a vinyl blade will not: the H623A is rated from -70 F to 425 F.
5) Is the Cal-Royal PG-601 aluminum channel perimeter gasketing an alternative to the NGP H623A brush door sweep?
No - they seal different parts of the opening. The NGP H623A is a door bottom sweep: an anodized aluminum housing that mounts to the face of the door with a 2-1/2 inch synthetic polyamide brush set at 45 degrees to close the gap between the door bottom and the threshold. The Cal-Royal PG-601 is aluminum channel perimeter gasketing with a vinyl insert, which applies to the frame around the head and hinge and strike jambs. An opening that needs both the bottom and the perimeter sealed takes one of each, not one in place of the other.
6) Do screws come with the NGP H623A door sweep, or do I have to buy them?
Screws are furnished. Each H623A ships with #6 x 3/4 inch stainless steel sheet metal screws, which is what you want on an exterior opening where a plated screw would rust and streak the door. The holes in the housing are slotted, so you can shift the sweep up or down before you tighten them.
7) Will an aluminum brush door sweep hold up in a walk-in cooler or a boiler room?
Temperature is not the limit here. The H623A runs from -70 F to 425 F, which covers freezer and cooler doors on the low end and mechanical and boiler rooms on the high end. The housing is 6063 aluminum with a T5 temper and an anodized finish, so it resists corrosion in damp rooms, and the synthetic polymer filament resists moisture.
8) I need to standardize the door sweeps across a whole building. Is the NGP H623A a commercial grade unit?
It is specified as commercial, not residential. For a fleet standardization the two things that matter are that one part number covers most of your openings and that it does not disqualify your labeled doors. The 42 inch length trims to fit standard single leaves and the 84 inch handles pairs, and the fire approval covers metal doors to 3 hours and wood to 60 minutes, so the same sweep goes on both your rated corridor doors and your unrated ones.
9) For a fire-rated opening, does a brush door sweep or a vinyl-insert gasket go at the bottom of the door?
The NGP H623A brush sweep is the one carrying a fire rating at the door bottom - it is approved for fire-rated metal doors up to 3 hours or wood doors up to 60 minutes, with a synthetic polyamide brush rated from -70 F to 425 F. The Cal-Royal PG-601 is a vinyl-insert perimeter gasket for the frame, so it is not the part that closes the bottom gap in the first place. On a rated opening, specify the H623A at the sill and treat perimeter gasketing as a separate line item for the jambs and head.
10) Does the NGP H623A brush sweep meet REACH and RoHS for a government or institutional spec?
Yes, the H623A materials are REACH and RoHS compliant. On public and institutional projects that is usually a submittal line item alongside the fire approval, and both are covered by the same part.
11) Will the brush on this NGP sweep flatten out after a season of use?
The filament is synthetic polyamide, chosen for abrasion resistance and memory retention, so it recovers its shape after being pushed over a threshold rather than staying laid flat. That is the practical difference on a high traffic entry door where a sweep gets worked hundreds of times a day.
