Cal-Royal BW-302 Nylon Brush Weatherstrip with Extruded Aluminum Seal Retainer

The Cal-Royal BW-302 Nylon Brush Weatherstrip is engineered and tested for durability and reliable performance, providing an energy-efficient door sealing solution for commercial applications. Featuring a high-quality nylon brush encased in an extruded aluminum seal retainer, this weatherstrip measures 1/4" (6.4mm) wide with a 3/4" (19.1mm) profile height, 5/8" (15.9mm) insert height, and 1-3/8" (35mm) total height. It seals the gap around the door between the bottom of the door and the top of the threshold or floor surface, restricting air, light, smoke, and insects from around the opening.

Key Features

  • Precise Sizing: Designed with a 1/4" (6.4mm) width, 3/4" (19.1mm) profile height, 5/8" (15.9mm) insert height, and 1-3/8" (35mm) total height for accurate fit and reliable sealing performance.
  • Heavy-Duty Construction: High-quality nylon brush encased in an extruded aluminum seal retainer provides durable, long-lasting performance in demanding commercial door applications.
  • Energy-Efficient Sealing: Prevents heat loss and infiltration of sound, light, drafts, insects, moisture, smoke, or fire, helping maintain climate control and comfort.
  • Versatile Compatibility: Suitable for use on either wood or hollow metal doors, including in-door sweep, jamb/header gasketing, and split astragal applications.
  • Adjustable Installation: Punched with slotted holes for adjustment, allowing precise fit during installation for optimal sealing contact.

Cal-Royal BW-302A-36 – Frequently Asked Questions

1) Can the Cal-Royal BW-302 brush weatherstrip be used as a door sweep, or is it only for the jamb?
Both. The BW-302 nylon brush seal mounts on either wood or hollow metal doors and is used as an in-door sweep at the bottom, as jamb and header gasketing, and in split astragal applications on pairs. As a sweep it closes the gap between the door bottom and the threshold or floor, cutting air, light, smoke, and insect infiltration.
2) What are the actual profile dimensions of the BW-302 brush seal?
The aluminum retainer is 1/4 inch (6.4mm) wide with a 3/4 inch (19.1mm) profile height. The brush insert stands 5/8 inch (15.9mm), and the total height retainer plus brush is 1-3/8 inch (35mm). Those numbers matter on a sweep: you need about 1-3/8 inches of clearance from the mounting line down to the floor for the brush to make contact without binding.
3) Is a nylon brush seal the right choice, or should I use a neoprene or foam gasket?
Brush is the better pick where the door drags or the floor is uneven, and where the seal has to ride over a threshold without the drag that a solid insert creates. It stops air, light, smoke, and insects. If you want a compression seal against a stop, a neoprene-insert strip like the Hager 862S or the jamb-mounted Hager 864S is the alternative, and for a kerfed frame the Pemko Q103W foam strip drops into the kerf instead of surface mounting.
4) I need a brush sweep on an exterior door that gets driving rain. Is the BW-302 the right model?
For an exterior opening where water has to be thrown clear of the door bottom, order the BWR-301 instead. It is the same brush seal with a rain drip added to deflect water. The BW-302 has no drip and is the plain retainer version.
5) What is the difference between the Cal-Royal BW-302 brush weatherstrip and a neoprene-insert weatherstrip like the Hager 862S?
The BW-302 seals with a nylon brush held in an extruded aluminum retainer, so the sealing element sweeps across the gap and tolerates a floor or jamb surface that is not perfectly flat. The Hager 862S uses a neoprene insert for smoke and draft control and comes in a 48 inch length, so it compresses against the stop rather than brushing. Both are weatherstrips; the BW-302 brush is the choice where the door drags dust or the gap varies, the neoprene insert where you want a compressed contact seal.
6) I need an adjustable jamb weatherstrip longer than 48 inches - what can I use instead of the Cal-Royal BW-302?
The BW-302 is supplied in 36 inch and 48 inch lengths, which covers door bottoms and head gasketing but not a full jamb leg in one piece. For a full-height jamb run, the Hager 864S is an 84 inch adjustable jamb weatherstrip in clear anodized aluminum with a neoprene insert. Use the 864S where you want one uncut piece down the hinge or strike jamb.
7) My door frame is kerfed - will the Cal-Royal BW-302 fit, or do I need something else?
The BW-302 is a surface-applied strip: an aluminum retainer punched with slotted holes that fastens to the face of a wood or hollow metal door or frame. It is not made to press into a kerf. For a kerfed frame, the Pemko Q103W is a kerf-in foam weatherstrip with an extended flange measuring 1-1/4 inch by 3/16 inch. Confirm your kerf width before ordering either.
8) My door bottom gap varies across the opening. Can this weatherstrip be adjusted after mounting?
Yes. The retainer is punched with slotted holes, so the strip can be shifted up or down at each fastener to follow an uneven floor or an out-of-square opening and keep the brush in contact across the full width.
9) What lengths and finishes does the Cal-Royal BW-302 come in?
Two lengths, 36 inch and 48 inch, each in mill Aluminum or Duronodic (dark bronze) finish. A 36 inch piece suits a standard 3-0 door; the 48 inch is for wider leaves or for cutting down to jamb and header runs.
10) Is there a simpler stick-on alternative to the screw-applied Cal-Royal BW-302?
The BW-302 mounts with fasteners through slotted holes in its aluminum retainer, which lets you adjust brush contact after the door is hung. If you want no drilling, the Hager 726S is a smoke seal weatherstrip with press-on installation in a charcoal finish. The trade-off is adjustability: the BW-302 can be shifted in its slots, the press-on 726S sets where you stick it.
11) For a standardized building package, can the Cal-Royal BW-302 handle door bottom, head and astragal, or do I need separate products?
The BW-302 is used as an in-door sweep, as jamb and header gasketing, and in split astragal applications, all from the same 1/4 inch wide, 1-3/8 inch total height profile in 36 inch and 48 inch lengths and Aluminum or Duronodic finish. That lets one item cover several positions in a commercial package. Where a position calls for a compression seal instead of a brush, peers such as the Hager 862S with neoprene insert cover smoke and draft control at 48 inches.
12) Is the BW-302 built for commercial traffic or is it a residential-grade strip?
It is a commercial product, with the nylon brush held in an extruded aluminum retainer rather than a vinyl or plastic carrier. Cal-Royal lists it for office buildings, schools, healthcare, retail, warehouses, multi-tenant residential, and government facilities.
13) Will the Duronodic finish on the BW-302 match dark bronze hardware on my other doors?
Duronodic is Cal-Royal's dark bronze anodized aluminum finish, and it is the option to specify when the openings already carry dark bronze closers, pulls, or thresholds. The other choice is plain aluminum, which reads silver and matches clear anodized frames. Both finishes are offered in the 36 inch and 48 inch lengths.
