Cal-Royal BTS-103DV-36 – Frequently Asked Questions

1) Will the Cal-Royal BTS-103 door sweep work on a hollow metal door, or is it only for wood?
Both. The BTS-103 mounts to the face of the door and is used on wood and hollow metal door assemblies alike. Because it is surface mounted rather than let into the door bottom, there is no routing or machining involved, so the door material only matters for the fasteners you drive. It is most often applied to the exterior face of an outswing door.
2) How much of a gap under the door will the BTS-103 sweep close?
The BTS-103 has a 7/8 inch (22.2mm) profile height, which is the portion of the vinyl that drops below the retainer to meet the floor, over a total height of 1-7/8 inches (47.6mm). The retainer projects only 1/4 inch (6.4mm) off the door face. Measure your undercut at the widest point of the sweep of the door: the slotted mounting holes let you slide the sweep up or down to fine tune contact with the threshold or floor rather than locking you to one position.
3) What length door sweep do I need for a 36 inch door?
Cal-Royal supplies the BTS-103 in 36 inch and 48 inch lengths. A 36 inch door leaf takes the 36 inch piece as is. For anything between, or for a pair of doors, buy the 48 inch and cut the extruded aluminum retainer down with a hacksaw or a miter saw and trim the vinyl to match. Cutting long is the safe move; you cannot add length back.
4) If my old aluminum and vinyl door sweep is worn out, will the Cal-Royal BTS-103 replace it?
In most cases yes, since the BTS-103 is the same style of part: an extruded aluminum retainer with a vinyl insert, screwed to the door face through slotted holes. What it is not is a drop in match for someone else's holes. The slots give you adjustment, but you should expect to drill fresh pilot holes rather than land on the old pattern. Before ordering, check that the old sweep is surface mounted on the face and not a kerf mounted or mortised door bottom, because those go into a groove in the door and the BTS-103 does not.
5) What is the closest equivalent to the Cal-Royal BTS-103 door bottom sweep from another manufacturer?
The Cal-Royal BTS-103 pairs an extruded aluminum retainer with a vinyl insert and surface mounts to the face of the door. The closest same-material equivalent is the NGP 101V vinyl door sweep, which uses a vinyl seal in an aluminum alloy housing. On the Pemko side, the 345V professional door bottom sweep carries a GREENGUARD Gold certified Eco-V insert in place of standard vinyl, and the Pemko 56 series door bottom sweep also uses an Eco-V insert in a 36 inch length. The BTS-103 comes in 36 inch and 48 inch lengths, so a 36 inch opening can be matched directly by the Pemko 56 or the Pemko 29326NB, both of which are 36 inch parts.
6) What door sweep should be used on a boiler room or kitchen door where the BTS-103 vinyl would not hold up to heat?
The Cal-Royal BTS-103 uses a vinyl insert, which is a general purpose commercial weatherseal material. For openings that see sustained high or very low temperatures, the NGP 200SA is a silicone door sweep in an anodized aluminum housing rated for a temperature range of -100 F to 500 F. The NGP 197NA is a neoprene door sweep in an anodized aluminum housing and is the other common step away from vinyl. All three share the same basic form, an aluminum housing carrying a replaceable seal strip fastened to the door face.
7) Will a Pemko 3452 rain drip do the same job as the Cal-Royal BTS-103 on an exterior outswing door?
No, and the two are frequently confused because both mount to the face of an exterior door near the bottom. The Cal-Royal BTS-103 is a door bottom sweep: an extruded aluminum retainer holding a vinyl insert that closes the gap between the door bottom and the floor against air, light, smoke, moisture, and insects. The Pemko 3452 is a surface plate rain drip door bottom, which sheds water running down the door face away from the opening. A rain drip does not contact the floor and does not seal the undercut. On a driving-rain exterior outswing opening the two are companions, not alternatives.
8) Can I mount the BTS-103 sweep on the inside of an inswing door?
It is a surface applied sweep, so it can be fastened to either face, but the BTS-103 is normally run on the exterior face of an outswing door. On an inswing door the sweep goes on the interior face so it does not foul the stop or the threshold as the door swings toward you. Either way it needs a flat, unobstructed face at the bottom rail and enough clearance for the 1/4 inch projection of the retainer.
9) Should I use a vinyl door sweep or a nylon brush sweep at the bottom of the door?
A vinyl insert like the one in the BTS-103 seals by wiping flat against the floor, so it blocks air, light, smoke, moisture and insects. That is what you want on an exterior opening or anywhere you are chasing drafts. A brush seal, such as the NGP 600 1/2 inch nylon brush door sweep or the Pemko 29326NB brush door bottom, drags less and copes better with rough or uneven floor surfaces such as broom finished concrete or carpet transitions, at the cost of a less positive seal against air and light. Smooth threshold, vinyl. Rough or irregular floor, brush.
10) What finishes does the Cal-Royal BTS-103 come in, and which one should I use on a bronze storefront?
Two: mill finish aluminum and dark bronze anodized aluminum, both with the vinyl insert, and both offered in 36 inch and 48 inch lengths. Dark bronze anodized is the one that disappears against a bronze anodized storefront or a dark painted hollow metal frame. Mill finish is the plain aluminum look and is the usual pick for back of house, service and warehouse doors where appearance is not driving the decision.
11) Is a door sweep enough to stop smoke, or do I need a gasketed door bottom?
The BTS-103 vinyl sweep restricts air, light, smoke, sound, moisture and insects at the bottom of the opening, and it is built for commercial door use. What it is not is a substitute for a rated assembly: if your opening carries a fire or smoke label, the sweep has to be part of the listed assembly for that door, and the requirement is set by the door and frame label, not by the sweep. For ordinary weather and draft sealing on a commercial opening it does the job on its own.
12) What are the alternatives to the Cal-Royal BTS-103 door bottom sweep?
Staying with vinyl on aluminum, the NGP 101V is the closest equivalent in another brand. If the opening sees heat or cold extremes, the NGP 200SA silicone sweep is rated for a temperature range of -100F to 500F. The NGP 197NA swaps the vinyl for neoprene in an anodized aluminum housing. For a lower profile look, the Pemko 29326NB uses a concealed fastener design so the screw heads do not show on the door face. On projects chasing indoor air quality credits, the Pemko 345V carries a GREENGUARD Gold certified Eco-V insert.
13) Will a door bottom sweep stop rain from getting under my exterior door?
The BTS-103 blocks moisture along with air, light and insects where the vinyl meets the floor, and that handles normal weather infiltration on an outswing exterior door. Driving rain running down the door face is a different problem, and it is solved with a drip cap rather than a sweep. The Pemko 3452 surface plate rain drip door bottom is the part for that, and it is commonly used together with a bottom sweep rather than instead of one.
14) I need to standardize door sweeps across a building. Can I use the BTS-103 on every opening?
For standard 36 inch commercial leaves the 36 inch BTS-103 covers the bulk of a building, and the 48 inch cuts down for anything odd, so one part number in one finish handles most of a fleet. The limits to watch: it is a surface mounted sweep, so openings with kerfed or mortised door bottoms need a different style, and doors with a bottom rail obstruction or an astragal at the meeting stile may not take a full length run. Everything else is a fastener change between wood and hollow metal.
15) Is there a door bottom sweep that hides the mounting screws the way the BTS-103 does not?
The Cal-Royal BTS-103 retainer is punched with slotted holes for adjustment, so the fasteners sit exposed on the door face where the installer can reach them to reset the seal height. If exposed screw heads are a concern on a visible entrance, the Pemko 29326NB is a 36 inch brush door bottom sweep in clear anodized aluminum built with a concealed fastener design. Note the trade: the 29326NB seals with brush filament rather than a vinyl blade, so it is a different seal type as well as a different fastening approach.
16) Can the same finish be matched across a building if some doors get the Cal-Royal BTS-103 and others get a different sweep?
The Cal-Royal BTS-103 is offered in mill finish aluminum with vinyl insert and in dark bronze anodized aluminum with vinyl insert, so a fleet of doors can be standardized to either a bright or a dark aluminum. Among the alternates, the NGP 197NA neoprene sweep and the NGP 200SA silicone sweep use anodized aluminum housings, and the Pemko 29326NB uses clear anodized aluminum, which reads closest to the mill finish BTS-103. Confirm the specific anodized color on the alternate before mixing it into a run of dark bronze BTS-103 doors.
17) What is the difference between the NGP 101V and the Cal-Royal BTS-103?
Both are the same class of part: a surface mounted door bottom sweep built as an aluminum housing carrying a vinyl seal. The Cal-Royal BTS-103 uses an extruded aluminum retainer with a vinyl insert, measures 1/4 inch in width, 7/8 inch in profile height and 1-7/8 inch in total height, and is punched with slotted holes for adjustment. The NGP 101V is a vinyl door sweep with an aluminum alloy housing. For a distributor filling a vinyl sweep line item, these are the two closest counterparts in the group, and the deciding factors are the retainer dimensions and the finish and length required at the opening.
18) If a tenant complains about noise and light under a door, is a brush sweep or the Cal-Royal BTS-103 the better fix?
For light and sound the continuous seal is what does the work. The Cal-Royal BTS-103 uses a vinyl insert in an extruded aluminum retainer and is built to restrict air, light, smoke, sound, moisture, and insects around the opening, giving an unbroken blade across the door bottom. A brush sweep such as the NGP 600 1/2 inch nylon brush or the Pemko 29326NB brush door bottom sweep uses filament, which passes more light and sound than a solid blade but tolerates uneven floors. Choose brush when the floor will not let a blade seal cleanly, and the vinyl BTS-103 when the floor is sound and blocking light and sound is the point.
