Cal-Royal BTN-112DN-36 – Frequently Asked Questions

1) Does the Cal-Royal BTN-112 sweep mount on the inside or the outside of the door?
Surface mounted to the face of the door, and on an outswing door it goes on the exterior face so the neoprene wipes the threshold as the door closes. Get that backwards on an outswing and the sweep rides on the inside of the stop and never touches the sill. On an inswing opening the sweep goes on the interior face instead, same hardware, same slotted adjustment.
2) Can I put a Cal-Royal BTN-112 sweep on a hollow metal door, or is it only for wood?
Both. The BTN-112 is rated for wood or hollow metal doors, which is what makes it usable across a mixed building where the exterior openings are hollow metal in steel frames and the interior or back-of-house doors are wood. Same part number either way; only the fastener you choose changes with the substrate.
3) What length Cal-Royal BTN-112 do I order for a 36 inch door?
The BTN-112 comes in 36 inch and 48 inch lengths. For a standard 3-0 door, the 36 inch piece is the direct match. The 48 inch is for wider leaves, or for cutting down to an odd width; the extruded aluminum retainer cuts cleanly with a hacksaw or a miter saw and the neoprene trims with a knife. Order one per leaf, so a pair of doors takes two.
4) Should I use a neoprene sweep or a brush sweep on a commercial exterior door?
Neoprene, like the insert on the Cal-Royal BTN-112, makes continuous contact with the threshold and is what you want when you are stopping air, light, smoke, and insects at an exterior opening. A brush sweep such as the NGP 600 nylon brush or the Pemko 29326NB brush bottom sweeps over rough or uneven floors and out-of-level thresholds with far less drag, and it tolerates carpet transitions, but bristles leak air compared to a solid seal. Rule of thumb: solid neoprene where the floor is flat and you care about infiltration, brush where the floor is rough or the door has to sweep over something.
5) I need to replace a worn neoprene door sweep on an anodized aluminum frame. Is the Cal-Royal BTN-112 a direct swap?
It is the same class of part, a surface-applied aluminum retainer with a neoprene insert, and it is the closest one-for-one to what you are pulling off. Because the retainer is punched with slotted holes, you get lateral and vertical play to pick up existing screw holes instead of drilling fresh ones in the door face. The equivalent from another brand is the NGP 197NA, a neoprene sweep in an anodized aluminum housing. Match the finish to the frame: dark bronze anodized for bronze openings, mill for clear aluminum.
6) Which door sweep has a certified low-emission insert for a green building project?
The Pemko 345V is a professional door bottom sweep with a GREENGUARD Gold certified Eco-V insert, and the Pemko 56 Series door bottom sweep also uses an Eco-V insert in a 36 inch length. The Cal-Royal BTN-112 uses a neoprene insert in an extruded aluminum retainer and is offered in 36 inch and 48 inch lengths. For a schools or healthcare project chasing indoor air quality credits, the 345V is the one carrying the GREENGUARD Gold certification on the insert.
7) What is the closest equivalent to the Cal-Royal BTN-112 door bottom sweep from NGP?
The NGP 197NA is the nearest match. Both are door bottom sweeps built on an aluminum housing with a neoprene sealing insert, so the sealing material against the door bottom is the same rubber compound in each. The BTN-112 carries an extruded aluminum retainer and neoprene insert and comes in mill finish aluminum and dark bronze anodized aluminum; the 197NA uses an anodized aluminum housing. For a property manager standardizing on neoprene sweeps across a building, either keeps the same insert material on the openings.
8) What should I use instead of the BTN-112 on a door that sees high heat or cold?
Look at the NGP 200SA silicone door sweep with an anodized aluminum housing, rated for a temperature range of -100 F to 500 F. The Cal-Royal BTN-112 is a neoprene-insert sweep in an extruded aluminum retainer intended for commercial weather sealing against air, light, smoke, and insects. On a mechanical room, boiler room, or kitchen door where the rubber sees extremes, the silicone 200SA is the one specified for that temperature span.
9) Is the Pemko 3452 rain drip a substitute for the Cal-Royal BTN-112?
No - they do different jobs and are often installed together. The Pemko 3452 is a surface plate rain drip door bottom, which sheds water running down the door face away from the threshold. The Cal-Royal BTN-112 is a surface-mounted door bottom sweep that closes the gap under the door against air, light, smoke, and insects with a neoprene insert in an extruded aluminum retainer. On an exterior outswing door taking driving rain, a contractor may want both: the drip above to shed water, the sweep to seal the gap.
10) I need a 48 inch door sweep - do the Pemko options cover that width?
The Cal-Royal BTN-112 is offered in a 48 inch length as well as 36 inch, in mill finish aluminum or dark bronze anodized aluminum with a neoprene insert. The Pemko 29326NB brush sweep is a 36 inch part, and the Pemko 56 Series sweep with Eco-V insert is likewise a 36 inch length. For a wide leaf or a pair of doors where 36 inches will not reach, the 48 inch BTN-112 covers the opening without splicing.
11) What finishes does the Cal-Royal BTN-112 door bottom sweep come in?
Two: mill finish aluminum and dark bronze anodized aluminum, both with the neoprene insert. Mill is the raw aluminum look and disappears against clear-anodized storefront and aluminum frames. Dark bronze anodized matches bronze storefront, dark painted hollow metal, and duranodic openings. Both finishes are stocked in 36 inch and 48 inch, so the finish choice does not limit your length.
12) What is the difference between the Cal-Royal BTN-112 and a vinyl door sweep?
The insert material. The BTN-112 carries a neoprene insert in an extruded aluminum retainer; a vinyl sweep such as the NGP 101V uses a vinyl blade in an aluminum alloy housing. Neoprene stays flexible in cold and holds up better to sun and ozone on an exterior door, which is why it is the usual pick for commercial entrances. Vinyl is the economy insert and is common on interior and light-duty openings. If the door sees extreme temperature, the NGP 200SA silicone sweep is the one rated from -100 F to 500 F.
13) Will a Cal-Royal BTN-112 sweep stop rain from driving under my exterior door?
It seals the gap at the door bottom against air, light, smoke, and insects, and a neoprene blade in contact with the threshold sheds most incidental water. Wind-driven rain on an exposed entrance is a different problem: for that you want a drip cap over the sweep, such as the Pemko 3452 surface plate rain drip door bottom, which throws water off the face of the door before it reaches the sweep line. On a protected or recessed entry, the BTN-112 alone is the normal treatment.
14) How much clearance does the Cal-Royal BTN-112 add to the face of the door, and will it hit the stop or the frame?
The retainer is 1/4 inch wide, so it stands 1/4 inch proud of the door face. On an outswing door mounted to the exterior, the sweep sits outside the frame stop and there is nothing to strike. On an inswing installation, check that 1/4 inch against your stop depth before you drill, since the sweep must clear the stop as the door swings shut. The 1-1/4 inch profile height is the visible band of the retainer down the bottom of the door.
15) Neoprene or vinyl door sweep - what is the difference for a commercial opening?
The Cal-Royal BTN-112 uses a neoprene insert in an extruded aluminum retainer. The NGP 101V is a vinyl door sweep in an aluminum alloy housing, and the NGP 197NA is a neoprene sweep in an anodized aluminum housing. Neoprene is the more rubber-like compound and vinyl the more plastic one, which changes how the seal behaves in cold and how it wears against a threshold over years of traffic. If a facility already runs vinyl sweeps, the 101V matches; if the standard is neoprene, the BTN-112 or the 197NA stays in family.
16) Which sweep hides the mounting screws?
The Pemko 29326NB brush door bottom sweep uses a concealed fastener design in a clear anodized aluminum body. The Cal-Royal BTN-112 mounts to the face of the door through slotted holes punched in the extruded aluminum retainer, which leaves the fasteners visible but lets an installer adjust the sweep height for a precise fit against the floor. Where appearance on a storefront or lobby door matters, the concealed-fastener 29326NB is the cleaner face; where the floor line varies and the sweep needs to be set by eye, the slotted BTN-112 gives that adjustment.
17) Do I need a threshold to go with a Cal-Royal BTN-112 door sweep?
Not strictly, but the sweep only seals against whatever surface is under the door. On a concrete slab or a finished floor it can bear directly; on an exterior opening you get a far better seal with a threshold to bear against, because it gives the neoprene a flat, level surface across the full width instead of following floor variation. Also budget for perimeter gasketing on the jambs and head if you are chasing air infiltration, since the bottom sweep only handles one of the four sides.
18) Is the Cal-Royal BTN-112 heavy enough for a high-traffic commercial entrance?
It is built for commercial service: extruded aluminum retainer rather than roll-formed, with the neoprene held in the extrusion instead of glued on. That is the construction that survives an entrance cycling all day, where a residential-grade sweep tears at the ends within a season. If you are standardizing across a portfolio, both lengths come in both finishes, so you can spec one part number per finish family and cover 36 inch and 48 inch leaves.
19) Are the mounting screws included with the Cal-Royal BTN-112, and what fasteners do I use on a hollow metal door?
The retainer arrives punched with slotted holes ready for fastening. Plan the fastener to the door: sheet metal screws into hollow metal, wood screws into a wood door. Because the holes are slotted rather than round, you set the sweep height against the threshold first and then tighten, which is how you get even contact across a door that has settled.
