NGP 675A-36 – Frequently Asked Questions

1) What lengths and finishes does the NGP 675 door sweep come in?
Two lengths, 36 inch and 84 inch, each in anodized aluminum or gold. The 36 inch covers a standard single door width; the 84 inch is the length you cut down for oversized openings or when you need to gasket a taller vertical run on the same profile.
2) Are the mounting screws included with the NGP 675, or do I need to buy them?
Screws are in the box: #6 x 3/4 inch stainless steel sheet metal screws. The holes in the retainer are slotted, so you can shift the sweep up or down to set brush contact on the threshold before you tighten and snap the cover on.
3) What is the difference between the NGP 675 door sweep and the Cal-Royal PG-601 perimeter gasketing?
Both are aluminum-channel perimeter sealing products, but they seal with different materials. The NGP 675 uses a synthetic polyamide nylon brush in a 7/16 inch profile, with a snap-on cover that conceals the screw heads. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing that seals with a vinyl insert. A brush seal sweeps across threshold irregularities and carpet transitions, while a vinyl insert compresses against a flat stop or door face, so the choice follows the opening rather than one being a general upgrade over the other.
4) I need a perimeter seal that uses a vinyl insert instead of a brush - what should I order?
Order the Cal-Royal PG-601, an aluminum channel perimeter gasketing with a vinyl insert. It is the vinyl-sealing counterpart to the NGP 675, which seals with a synthetic polyamide nylon brush rather than a vinyl bulb or fin. Choose the vinyl insert where you want a compression seal against a stop, and the NGP 675 brush where the seal has to ride over an uneven or carpeted floor.
5) Do the screw heads show after installing the NGP 675 sweep?
No. A snap-on aluminum cover clips over the retainer once the sweep is fastened, hiding the screw heads. That also makes it harder to back the screws out without tools, which is why it gets used on tenant and public-side doors.
6) Should I use a nylon brush sweep or a vinyl blade sweep on my door?
Brush is the choice where the floor is uneven, swept by traffic, or where you want low drag: the polyamide nylon filament flexes over tile joints, carpet edges and grit without the squeal or drag a vinyl blade gives, and it keeps its memory rather than taking a set. Vinyl seals tighter against a smooth, flat threshold and does better as a straight air and water barrier. If you want a vinyl-insert aluminum channel instead, the Cal-Royal PG-601 perimeter gasketing uses a vinyl insert in an aluminum channel.
7) Will a nylon brush sweep hold up on a hot mechanical room or boiler room door?
The 675 brush is rated from -70 F to 425 F, so heat from a boiler or mechanical space is within range, as is an unheated exterior door in a cold climate. The retainer is 6063-T5 aluminum, which resists corrosion in damp areas.
8) How much does the NGP 675 sweep project off the face of the door?
It is a 7/16 inch profile, so the retainer and cover sit close to the door face. That matters on doors with a closer arm, a bottom rail push plate, or a tight astragal, where a deeper sweep body would foul.
9) For a high-heat or freezer-adjacent door, is the Cal-Royal PG-601 an equivalent substitute for the NGP 675?
They are not equivalent on temperature. The NGP 675 is rated for service from -70 F to 425 F with its aluminum alloy 6063-T5 channel and polyamide nylon brush. The Cal-Royal PG-601 is an aluminum channel gasketing that seals with a vinyl insert, a different sealing material with different thermal behavior. Where the specification on the drawing calls out an extreme temperature range, specify the NGP 675 and confirm the seal material against that requirement.
10) I want concealed fasteners on a tenant entry door - does the Cal-Royal PG-601 give me that?
The NGP 675 is the one built for that. Its snap-on cover conceals the screw heads for a clean appearance and added tamper resistance, and the slotted screw holes let you align the sweep before the cover goes on. It ships with #6 x 3/4 inch stainless steel sheet metal screws. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert and is specified on sealing material rather than on a concealed-fastener cover.
11) Can I use the NGP 675 sweep on doors in a hospital or school, or is it a residential part?
It is specified as a commercial product, and NGP lists it for office buildings, schools, healthcare, retail, industrial and warehouse space, multi-tenant residential and government buildings. Materials comply with REACH and RoHS, which matters on institutional and government purchases with environmental criteria.
12) Can I cut the 84 inch NGP 675 sweep down to fit a 36 inch door?
Yes. The 675 is an aluminum retainer with a snap-on cover and a brush insert, all of which cut to length with a hacksaw or chop saw. If all you need is one standard single door, the 36 inch is the ready size; buy the 84 inch when you are cutting multiple short pieces or covering an oversized leaf.
13) Will a brush door sweep keep insects and rodents out at the bottom of the door?
The nylon brush closes the gap along the full door width and the material is moisture resistant and retains insecticides well, which is why brush sweeps get used for pest exclusion at ground-level doors. Set the brush so the filaments just contact the threshold, using the slotted holes, before snapping the cover on.
