Cal-Royal BTSR-107 Door Bottom Sweep with Rain Drip for Outswing Exterior Doors

The Cal-Royal BTSR-107 is a surface-mount door bottom sweep engineered specifically for outswing exterior doors. Its integrated rain drip profile deflects water away from the door bottom, making it the right choice for exposed exterior applications where moisture infiltration is a concern. Constructed with an extruded aluminum retainer and vinyl insert, the BTSR-107 seals the gap at the door bottom against air, light, drafts, insects, moisture, smoke, and sound. It is compatible with both wood and hollow metal doors and is available in 36" and 48" lengths to fit standard commercial door widths.

Key Features

  • Rain Drip Design: The BTSR prefix rain drip profile deflects water away from the door bottom, ideal for outswing exterior doors exposed to the elements.
  • Surface Mount Installation: Mounts to the face of the door with no door modification required, simplifying retrofit and new installations.
  • Durable Construction: Extruded aluminum retainer paired with a vinyl insert provides a long-lasting, weather-resistant seal.
  • Broad Door Compatibility: Works with both wood and hollow metal doors for versatile application across commercial door types.
  • Field-Adjustable Fit: Slotted mounting holes allow for on-site adjustment to achieve proper seal alignment.
  • Length Options: Available in 36" and 48" lengths to accommodate standard exterior door widths.
  • Precise Profile Dimensions: Features a 7/16" (11.5 mm) width, 1-1/4" (31.8 mm) profile height, and 1-9/16" (39.5 mm) total height for a consistent, engineered seal.

Cal-Royal BTSR-107DV-36 – Frequently Asked Questions

1) Do I have to machine the door to install a BTSR-107 rain drip sweep?
No cutting or morticing. The BTSR-107 surface mounts to the face of the door, and the mounting holes are slotted so you can shift it up or down on site to close the gap to the threshold. That makes it a straight retrofit on an existing opening as well as a new install.
2) Will the Cal-Royal BTSR-107 mount on a hollow metal door, or is it wood only?
Both. The BTSR-107 is rated for wood and hollow metal doors, which covers most commercial exterior openings. Because it fastens through the door face rather than into the bottom edge, the substrate only has to hold the screws.
3) What size door does the Cal-Royal BTSR-107 sweep cover, and can I cut it down?
Two lengths, 36 inches and 48 inches. The 36 inch covers a standard 3-0 commercial leaf and the 48 inch covers wider leaves or lets you trim to an odd width. The retainer is extruded aluminum, so it cuts to length with a hacksaw or a miter saw and the vinyl insert trims with a knife. Order the next size up from your leaf width, never down.
4) Should I use a vinyl sweep like the BTSR-107 or a brush sweep on an exterior door?
Vinyl for weather, brush for sweeping. The BTSR-107 pairs an extruded aluminum retainer with a vinyl insert, which makes contact with the threshold and blocks air, light, drafts, insects, moisture, smoke, and sound. A brush seal, like the NGP 600 1/2 inch nylon brush sweep or the Pemko 29326NB brush door bottom, rides over uneven or carpeted floors more easily but does not seal water the way a vinyl blade does. On an exposed exterior door, go vinyl.
5) What is the difference between the Cal-Royal BTSR-107 and the Pemko 3452 for an outswing exterior door?
Both are rain drip door bottoms for outswing exterior openings. The Cal-Royal BTSR-107 is a door bottom sweep with an integrated rain drip profile, built from an extruded aluminum retainer with a vinyl insert, surface mounted to the face of the door with slotted holes for field adjustment, in 36 inch and 48 inch lengths. The Pemko 3452 is a surface plate rain drip door bottom, which puts the drip on a mounted plate rather than combining it into the sweep retainer. If you want one part that both seals the bottom gap and sheds water, the BTSR-107 does both; if the opening already has a sweep you intend to keep, the 3452 addresses the water alone.
6) What should I use instead of the Cal-Royal BTSR-107 on an interior door where there is no weather exposure?
The rain drip on the Cal-Royal BTSR-107 exists to deflect water away from the door bottom on outswing exterior doors, and it does nothing on a protected interior opening. For interior work, the Pemko 56 Series door bottom sweep with Eco-V insert in 36 inch length or the Pemko 345V professional door bottom sweep with a GREENGUARD Gold certified Eco-V insert are plain sweeps without the drip profile. Both seal the bottom gap; neither adds the water deflection you do not need indoors.
7) How much clearance does the BTSR-107 need under the door?
The profile measures 7/16 inch (11.5 mm) wide, 1-1/4 inch (31.8 mm) profile height, and 1-9/16 inch (39.5 mm) total height. The vinyl insert has to reach the threshold to seal, so the sweep body sits on the door face with the insert hanging below the bottom edge. With slotted holes you set that drop on site to suit your undercut rather than being locked to one dimension.
8) What finishes does the Cal-Royal BTSR-107 come in for matching existing storefront hardware?
Mill finish aluminum and dark bronze anodized aluminum, both with the vinyl insert. Mill finish is the raw silver aluminum that blends with clear anodized frames and standard aluminum entrances. Dark bronze anodized matches bronze storefront and dark painted hollow metal. Both finishes are offered in 36 inch and 48 inch.
9) I need a rain drip on an exterior door but the BTSR-107 finish or length is wrong for my opening. What else is there?
The Pemko 3452 surface plate rain drip door bottom is the other drip-style product carried alongside the Cal-Royal. It is a surface-mounted rain drip door bottom like the BTSR-107, so it serves the same outswing exterior application. Note that a separate drip cap mounted above the door handles rain running down the face; the BTSR-107 addresses water at the door bottom.
10) Will a vinyl door sweep like the BTSR-107 hold up on a door next to a boiler room or a walk-in freezer?
Extreme temperature is where a vinyl insert is the wrong pick. The BTSR-107 uses a vinyl insert, which is aimed at normal exterior weather exposure. For a door seeing severe heat or cold, the NGP 200SA silicone door sweep is rated from -100 F to 500 F. Neoprene is the other option for tougher service, as on the NGP 197NA.
11) Which door sweep holds up better than a vinyl insert at high or low temperatures?
The Cal-Royal BTSR-107 carries a vinyl insert in an extruded aluminum retainer, which suits ordinary commercial exterior openings. Where the opening sees extreme temperature, the NGP 200SA silicone door sweep with anodized aluminum housing is rated for a temperature range of -100 F to 500 F. The NGP 197NA neoprene door sweep with anodized aluminum housing is another elastomeric alternative to vinyl. Neither NGP sweep carries the rain drip profile the BTSR-107 has, so on an outswing exterior door you would be trading water deflection for the different insert material.
12) I need a vinyl door sweep but not the rain drip. What is the closest thing to the Cal-Royal BTSR-107?
The NGP 101V vinyl door sweep with an aluminum alloy housing is the nearest match on materials: a vinyl sealing element carried in an aluminum housing, the same construction pairing the Cal-Royal BTSR-107 uses with its extruded aluminum retainer and vinyl insert. The difference is the BTSR-107 adds the rain drip profile for outswing exterior doors. On a protected opening, or an inswing door where the drip serves no purpose, the 101V covers the sealing function.
13) Are surface mounted fasteners a problem, and is there a concealed fastener door bottom sweep instead?
The Cal-Royal BTSR-107 mounts to the face of the door with no door modification, and its slotted holes stay accessible so the seal height can be adjusted on site after hanging. Where the exposed fastener line is not wanted, the Pemko 29326NB 36 inch brush door bottom sweep uses a concealed fastener design in clear anodized aluminum. That trade goes the other way on service: concealed fasteners give a cleaner face, visible slotted holes give a maintenance crew a sweep they can re-set without pulling the assembly.
14) Which door bottom sweep should I specify for a project with green building or low-emission material requirements?
The Pemko 345V professional door bottom sweep carries a GREENGUARD Gold certified Eco-V insert, and the Pemko 56 Series door bottom sweep in 36 inch length also uses the Eco-V insert. Those are the ones to put in front of a specifier working to a low-emission materials requirement. The Cal-Royal BTSR-107 uses a vinyl insert in an extruded aluminum retainer and is the choice where the outswing exterior rain drip is the governing requirement.
15) Is the Cal-Royal BTSR-107 sweep good enough for a high-traffic commercial entrance, or is it a residential part?
Commercial. The BTSR-107 is a commercial-duty part, built with an extruded aluminum retainer rather than a stamped or plastic housing, and it is used on office buildings, schools, healthcare facilities, retail, warehouses, multi-tenant residential, and government buildings. For a fleet of exterior doors across a property, the two lengths and two finishes let you standardize on one part number.
16) Does the Cal-Royal BTSR-107 sweep help with sound and light leaks, or just water?
Both. Beyond the rain drip function, the BTSR-107 seals the gap at the door bottom against air, light, drafts, insects, moisture, smoke, and sound. On a door where the complaint is a light strip at the floor or noise bleeding into a corridor, the same part solves it, as long as the opening is an outswing door where the drip profile belongs.
17) Can I standardize one door sweep across both the exterior entrances and the interior doors in a building?
Most facilities end up with two parts rather than one. The Cal-Royal BTSR-107 covers the outswing exterior entrances, where the rain drip deflects water off the door bottom, and it comes in 36 inch and 48 inch lengths in mill finish aluminum or dark bronze anodized aluminum, both with a vinyl insert, so the exterior openings can match visually across the elevation. Behind the entrance, a plain sweep such as the Pemko 56 Series with Eco-V insert in 36 inch length handles interior doors without the drip. Standardizing means picking one exterior sweep and one interior sweep, not one sweep for the whole building.
