Pemko 18137CNB 36 – Frequently Asked Questions

1) Will the Pemko 18137 brush sweep work on a hollow metal door, or is it only for wood?
Both. The 18137 brush gasketing mounts to hollow metal and wood doors, and the same profile gets used on overhead, sectional, sliding and automatic doors. The retainer is drilled with slotted holes, so you set the brush height against the actual floor condition rather than the nominal gap. That matters on hollow metal frames where the slab has settled or the floor is not level.
2) How much gap can a Pemko 18137 door sweep actually cover?
The nylon brush itself is 1.375 inches long, sitting in an aluminum retainer 0.875 inch tall, for a 2-1/4 inch overall height and a 1/4 inch width. That brush length is what closes the gap, and because the filaments flex, it keeps contact across a slightly uneven floor instead of dragging on the high spot and lifting off the low one. Set the retainer high on the slots and you cover less; drop it and you sweep more, up to the brush length.
3) What length Pemko 18137 sweep do I order for a 36 inch door, and can I cut it down?
The 18137 comes in 36, 48, 84 and 96 inch lengths. A 36 inch door leaf takes the 36 inch piece. The 84 and 96 inch lengths are there for tall or oversized openings and for running the profile vertically on jambs and on overhead and sliding doors. Aluminum retainer with nylon filament cuts cleanly with a hacksaw or a fine tooth blade, so buying long and trimming to the leaf is normal practice.
4) Is the Pemko 18137 rated for a fire door assembly?
Yes. The 18137 brush gasketing is UL 4L10 listed and compliant with UL 1784 (air leakage) and UL 10C (positive pressure fire door tests), and it is certified to ANSI/BHMA A156.22, the standard for door gasketing and edge seals. It is also GREENGUARD Gold certified, which is what gets asked for on schools and healthcare projects chasing indoor air quality credits.
5) Brush sweep or a neoprene/vinyl sweep, which should I use under my door?
Brush is the choice when the floor is uneven, the door gets heavy traffic, or the sweep has to slide over carpet and thresholds without binding. Nylon filaments flex over a high spot and spring back; a solid neoprene or vinyl blade drags and tears there. Brush also holds up in temperature extremes, rated from -40F to a melting point above 400F. Where you need a tighter seal against water or a harder stop against air on a flat, true floor, a neoprene insert type like the Hager 862S is the better fit. For jamb sealing rather than the bottom of the door, the Hager 864S is an adjustable jamb weatherstrip with a neoprene insert.
6) What is the closest nylon brush door sweep to the Pemko 18137?
The Cal-Royal BW-302 is the nearest brush-type equivalent. Like the Pemko 18137, it uses a nylon brush insert held in an extruded aluminum seal retainer, so it addresses the same under-door and perimeter gap sealing with the same insert material and the same aluminum-carrier construction. The 18137 uses a brush insert in a 6063-T6 aluminum casing, 1-3/8 inch brush on a 7/8 inch casing for a 2-1/4 inch overall height and a 1/4 inch width, and is supplied in clear anodized and dark bronze anodized aluminum in 36, 48, 84 and 96 inch lengths. Specify the BW-302 when you want the same brush sealing approach from the Cal-Royal Brush Weatherstrips Series.
7) I need a smoke and draft seal instead of a brush - what should I use?
Move to a neoprene-insert weatherstrip. The Hager 862S is a 48 inch weatherstrip with a neoprene insert built for smoke and draft control, and the Hager 726S is a smoke seal weatherstrip in a charcoal finish that installs press-on rather than through fasteners. The Pemko 18137 seals with a compressed nylon brush in an aluminum casing, which conforms to slightly uneven floors and reduces infiltration of smoke, fumes, weather and light, and it is drilled with slotted holes for adjustment at install. A brush and a compression neoprene insert behave differently at the opening, so pick by the seal type the opening calls for.
8) Can I use the Pemko 18137 on the door jamb instead of the bottom of the door?
For a jamb application, look at the Hager 864S, an 84 inch adjustable jamb weatherstrip in clear anodized aluminum with a neoprene insert - it is built as a jamb piece and adjusts in position on the frame. The Pemko 18137 is a door sweep: a nylon brush in an aluminum casing that seals the gap under and around the door, and it is drilled with slotted holes for positioning during installation. Both are offered in clear anodized aluminum, so the finish can match across the opening.
9) Will the Pemko 18137 keep mice and bugs out from under a warehouse door?
That is one of the main reasons brush gets specified on industrial and warehouse openings. The filaments are densely compressed nylon, and the material naturally repels rodents and spiders rather than giving them something soft to chew through. It also cuts the infiltration of smoke, fumes, weather and light. On a loading dock or a sectional overhead door where the slab is not perfectly flat, the brush conforms where a rigid seal leaves a channel.
10) What finishes does the Pemko 18137 brush sweep come in, and will it match my storefront?
Two anodized finishes: satin aluminum clear anodized and dark bronze anodized. Both are available in every length offered (36, 48, 84 and 96 inches). Clear anodized matches standard aluminum storefront and mill finish frames; dark bronze matches bronze anodized storefront and dark painted hollow metal. Anodizing is on the 6063-T6 extrusion itself, so it holds up on exterior openings.
11) Can I use the Pemko 18137 on an exterior door in a cold climate?
Yes. The brush is rated highly flexible down to -40F, so the filaments do not go stiff and stop sealing in winter, and the upper end is a melting point above 400F. The retainer is 6063-T6 aluminum with a temper retainer, an extrusion alloy used for exterior architectural work. That temperature span is why the same part shows up on cold storage, unconditioned warehouses and exterior entrances alike.
12) What is a comparable nylon brush weatherstrip to the Pemko 18137 if I need another brand?
The Cal-Royal BW-302 is the closest like-for-like, a nylon brush weatherstrip in an extruded aluminum seal retainer, same construction concept as the 18137. If what you actually need is a smoke seal rather than a brush sweep, the Hager 726S is a press-on smoke seal weatherstrip in charcoal, which is a different job: it seals the door to the stop, not the bottom of the door to the floor. Swapping one for the other is the common mistake.
13) Is the Hager 726S a drop-in substitute for the Pemko 18137?
No - it looks like a seal for the same opening but it is a different part. The Hager 726S is a smoke seal weatherstrip that installs press-on in a charcoal finish. The Pemko 18137 is a mechanically fastened brush sweep, drilled with slotted holes so it can be shifted during installation, with a nylon brush in a 6063-T6 aluminum casing at 2-1/4 inch overall height and 1/4 inch width, supplied in clear anodized and dark bronze anodized aluminum. A press-on smoke seal does not give you the adjustable aluminum-carried brush, and a brush sweep does not install the way a press-on seal does.
14) I need a longer piece than 84 inches for a tall opening - what are my options?
The Pemko 18137 brush sweep runs to 96 inches in both clear anodized and dark bronze anodized aluminum, with 36, 48 and 84 inch lengths below that, so a tall leaf can be covered from one piece. Among the alternatives, the Hager 864S is supplied at 84 inches and the Hager 862S at 48 inches. If the run needs to reach 96 inches in a single length, the 18137 is the one that covers it.
15) Which of these seals holds up to high heat and rough floors in a warehouse?
The Pemko 18137 is the one to specify there. Its compressed nylon filaments stay flexible from -40 degrees Fahrenheit to a melting point above 400 degrees Fahrenheit, the brush automatically adjusts to slightly uneven floors, and the filaments are carried in a 6063-T6 aluminum alloy casing with temper retainer. It is a commercial-rated part and carries GREENGUARD Gold, UL 4L10, UL 1784, UL 10C and ANSI/BHMA A156.22. The neoprene-insert alternatives, the Hager 862S and Hager 864S, seal by compression against a flatter, more consistent surface, which is a different behavior on a floor that is out of level.
16) Is the Pemko 18137 a commercial grade sweep or a residential one?
Commercial. The 18137 is built for commercial door hardware duty, extruded 6063-T6 aluminum rather than a formed strip, and it is what gets specified on office buildings, schools, hospitals, warehouses, retail, government buildings and multi-tenant residential. For a property manager standardizing across a portfolio, the two anodized finishes and four lengths cover most leaf sizes with one part number on the PO.
17) Does the Pemko 18137 door sweep come with screws, and how does it mount?
The 18137 retainer arrives drilled with slotted holes for surface mounting to the face of the door. The slots let you slide the assembly up or down before you tighten, which is how you dial in brush contact on a door that swings over an uneven floor or a threshold. Mount it, close the door, check the sweep along the full width, then set your fasteners.
