Pemko 18061CNB 36 – Frequently Asked Questions

1) What size gap will a 5/8 inch nylon brush door bottom close?
The nylon brush on the 18061 drops 5/8 inch below the retainer, so it will sweep an undercut up to roughly that. The retainer itself is 1-1/8 inch wide by 1/4 inch tall, which is the part that fastens flat to the door face. Brush is the right pick over a rubber or neoprene sweep when the floor is carpet, uneven concrete, or a threshold the door drags on, because the filaments flex instead of binding.
2) What length Pemko 18061 do I order for a 36 inch door?
Order the 36 inch. The 18061 comes in 36, 42, 48, 84, and 96 inch lengths, so match the door width for a standard opening and cut down as needed. The 84 and 96 inch pieces are there for oversized or double-egress openings, and for cutting multiple short pieces from one stick.
3) Is the Pemko 18061 a surface-mounted door bottom or does it mortise into the door?
Surface applied. The 180-degree aluminum retainer screws to the face of the door at the bottom rail, with the brush hanging below. No routing, no mortising, no door prep beyond drilling the fastener holes, which is why it's the usual retrofit choice on doors already hung. Total retainer footprint is 1-1/8 inch wide by 1/4 inch tall.
4) What else besides a door bottom do I need to seal a fire-rated opening?
A door bottom like the 18061 handles the undercut only. The head and jambs need their own gasketing. For the frame sides, the Hager 864S is a clear anodized aluminum adjustable jamb weatherstrip with a neoprene insert, and the Hager 726S is a press-on smoke seal in charcoal if you're retrofitting a frame without stopping to drill. Order the door bottom and the perimeter gasketing together or you've sealed three sides of four.
5) What is the closest nylon brush alternative to the Pemko 18061 door bottom weatherstrip?
The Cal-Royal BW-302 is the nearest match in construction: it is a nylon brush weatherstrip with an extruded aluminum seal retainer, the same retainer-plus-brush arrangement the Pemko 18061 uses with its aluminum retainer and 5/8 inch nylon brush insert. Where the two part company is on the certification package. The Pemko 18061 is BHMA certified, UL10C fire rated for positive pressure, UL1784 smoke tested, and GREENGUARD Gold certified, so it is the one to specify when the door bottom has to go on a fire door assembly and satisfy an inspector. For a non-rated opening where you just want a brush sweep in an aluminum retainer, the BW-302 covers the same mechanical job.
6) Is the Hager 864S a substitute for a Pemko 18061 door bottom?
No, and the confusion is worth clearing up because both are aluminum weatherstrip. The Hager 864S is an adjustable jamb weatherstrip with a neoprene insert in clear anodized aluminum, 84 inches long, so it mounts on the frame and seals the perimeter where the door face meets the stop. The Pemko 18061 is a door bottom: a 180 degree aluminum retainer with a 5/8 inch nylon brush that mounts on the bottom rail of the door and sweeps the threshold. On a fire door being gasketed completely you are likely buying both, the 864S up the jambs and across the head and the 18061 along the bottom, not one in place of the other.
7) Does the Pemko 18061 door bottom come in dark bronze to match my existing hardware?
Both finishes are anodized aluminum: clear and dark bronze. Every one of the five lengths (36, 42, 48, 84, 96 inch) is offered in each finish, so a property manager standardizing a building can hold one finish across mixed door widths.
8) For a smoke and draft control opening, should I use the Pemko 18061 or a neoprene insert weatherstrip like the Hager 862S?
It depends on where the seal sits and how much movement it has to tolerate. The Hager 862S is a 48 inch weatherstrip with a neoprene insert intended for smoke and draft control, a compressible elastomeric seal. The Pemko 18061 uses a 5/8 inch nylon brush in an aluminum retainer and is UL1784 smoke tested as well as UL10C fire rated for positive pressure, so it carries smoke credentials in a brush format. Brush is the usual choice at the door bottom because it sweeps over carpet, uneven slab, and threshold transitions without dragging the way a solid seal does. Neoprene is the usual choice where the door lands against a stop and can compress the seal squarely.
9) I need a dark finish door bottom. Which of these comes in a dark color?
The Pemko 18061 is offered in dark bronze anodized aluminum as well as clear anodized aluminum, in 36, 42, 48, 84, and 96 inch lengths, so a dark bronze door in a lobby or a bronze-finish storefront can be sealed without a bright aluminum line across the bottom rail. Among the comparable aluminum weatherstrips, the Hager 864S jamb weatherstrip is a clear anodized aluminum piece, and the Hager 726S smoke seal is a press-on strip in charcoal. If you are matching dark hardware at the door bottom specifically, the 18061 in dark bronze anodized is the direct route.
10) Can I cut a Pemko 18061 down to fit a narrower door?
Yes. The retainer is extruded aluminum, so it cuts to length with a hacksaw or a miter saw with a non-ferrous blade, and the nylon brush trims with it. Buyers doing a run of openings often order the 96 inch and cut two pieces from it. Take the 1-1/8 inch retainer width into account at the hinge and lock edges so the ends clear the stops.
11) Will a brush door bottom hold up in a high-traffic building?
The 18061 is a commercial-rated assembly: extruded aluminum retainer with a nylon brush insert, not a residential vinyl sweep. Nylon filaments recover after being deflected, so it tolerates the constant cycling of a stairwell or corridor door better than a rubber sweep that takes a set and stops sealing. Anodized finish on the aluminum is what handles the scuffing at floor level.
