Cal-Royal DSR-406DV-36 – Frequently Asked Questions

1) Will the Cal-Royal DSR-406 door shoe work on a hollow metal door, or is it only for wood?
Both. The DSR-406 is an aluminum channel with a flexible vinyl insert that mounts to the underside of the door, and it's made for either wood or hollow metal doors. That covers most commercial openings, so if you're standardizing sweeps across a building with a mix of wood office doors and hollow metal stair or service doors, the same shoe handles both.
2) How much clearance do I need under the door for a Cal-Royal DSR-406 door shoe?
Figure on the shoe adding 1-1/2 inches (37.8mm) of total height below the door bottom, with a 1-1/4 inch (31.4mm) profile height and a width of 1-13/16 inches (46.3mm) across the bottom edge. The 1-1/2 inch total is the number that matters for undercut: if the door bottom to threshold or finished floor gap is smaller than that, the shoe drags. Measure the existing gap before you order.
3) Is the Cal-Royal DSR-406 door shoe fire rated, and what should I use on a fire door instead?
The Cal-Royal DSR-406 is an aluminum door shoe with a rain drip and vinyl insert for wood or hollow metal doors. When the opening is a rated assembly, the Pemko 215 is a fire-rated door shoe with a rain drip and Eco-V insert that is UL10C certified, and the Pemko 210 is a fire-rated door bottom shoe with an Eco-V insert in 36 inch aluminum construction. The 215 keeps the drip; the 210 is the rated shoe without it.
4) What is the closest equivalent to the Cal-Royal DSR-406 door shoe with a rain drip?
The Pemko 211V is an L-shaped door shoe with a rain drip and a GREENGUARD Gold certified Eco-V insert, so it covers the same job as the Cal-Royal DSR-406: an aluminum channel with a flexible vinyl insert applied to the underside of the door, with a drip that deflects water away from the face. The DSR-406 measures 1-13/16 inch wide, 1-1/4 inch profile height and 1-1/2 inch total height and mounts to wood or hollow metal doors. If the drip is what the opening needs, the 211V is the direct cross to check dimensions against.
5) What's the difference between a door shoe with a rain drip and a plain door sweep?
A door sweep just seals the gap under the door. A shoe like the DSR-406 wraps the bottom edge of the door, so it seals and protects that edge, and the DSR prefix means it carries a rain drip that throws water clear of the door face instead of letting it run down and sit at the bottom rail. Use the rain drip version on exterior openings and anywhere weather hits the door. On interior openings where you only need to stop drafts, light, dust and smoke, a shoe without the drip is enough.
6) Can I adjust a Cal-Royal DSR-406 door shoe after it's mounted to get an even seal?
Yes. The aluminum channels are punched with slotted holes rather than round ones, so you can slide the shoe up or down before you tighten the fasteners. That matters on a door that has settled or a floor that isn't dead level, since you can dial in contact along the sweep instead of shimming.
7) What lengths and finishes does the Cal-Royal DSR-406 door shoe come in?
Two lengths, 36 inches and 48 inches, each available in mill finish aluminum or dark bronze anodized aluminum, both with the vinyl insert. A 36 inch piece covers a standard 3-0 door leaf. The 48 inch piece is for wider leaves, or you cut it down to the leaf width you actually have. Mill finish disappears against aluminum storefront and hollow metal; dark bronze matches bronze anodized frames and darker entrances.
8) What else could I use instead of a Cal-Royal DSR-406 if I still want the rain drip?
The Pemko 211V is the closest cross-brand match, an L-shaped door shoe with a rain drip and a GREENGUARD Gold certified Eco-V insert. Same job, water thrown clear of the door and the bottom edge sealed. If the GREENGUARD certification matters to your spec, that's the one to pull. If it doesn't, the DSR-406 does the same work in aluminum with a vinyl insert.
9) My loading dock doors see freezing winters and hot summers. Is a vinyl insert door shoe the right pick?
For extreme temperature swings, the NGP 112 uses a neoprene seal on an aluminum alloy base and is rated for a temperature range of -20F to 200F, which is the spec to point at for unconditioned dock and warehouse openings. The DSR-406's vinyl insert is the general commercial choice and it adds the rain drip for weather deflection, so on an exposed dock door that sees rain more than it sees hard cold, it's still the better seal.
10) Will a Cal-Royal DSR-406 door shoe stop light and smoke from coming under the door?
Yes. Fitted to the door bottom, the DSR-406 restricts air, light, smoke and insects around the opening, and the vinyl insert keeps enough flex to hold contact across the sweep. It's the part you use on tenant corridors and classroom doors where light spill and drafts are the complaint. It is not a rated smoke seal, so on a labeled opening go to a rated shoe instead.
11) I do not need the rain drip on an interior door - what is a simpler door shoe than the Cal-Royal DSR-406?
The rain drip on the Cal-Royal DSR-406 exists to deflect water away from the door face, which earns its keep on an exterior opening. On an interior door the Pemko 209 door shoe with an Eco-V vinyl insert is the plainer profile at 1/2 inch by 1-3/8 inch, and the NGP 12T is a thermoplastic door shoe with a mill aluminum base and vinyl fins. Both are drip-free channels that still seal the door bottom.
12) What door shoe holds up on a cold or hot exterior opening where a vinyl insert may not?
The Cal-Royal DSR-406 uses a flexible vinyl insert in an aluminum channel. Where the temperature swing at the opening is the concern, the NGP 112 is a neoprene door shoe with aluminum alloy construction rated for a temperature range of -20 F to 200 F. That is the trade to weigh on a loading dock, a mechanical room, or a north-facing entrance: neoprene seal material versus vinyl in the same style of aluminum channel.
13) I need a 48 inch door shoe with a rain drip - what are my options?
The Cal-Royal DSR-406 comes in 36 inch and 48 inch lengths, in mill finish aluminum and dark bronze anodized aluminum, both with the vinyl insert. Among the drip-style crosses, the Pemko 211V is an L-shaped door shoe with a rain drip, while the Pemko 210 fire-rated door bottom shoe is a 36 inch aluminum construction. On a 48 inch leaf, the DSR-406 already covers the width in a stock length.
14) Which door shoe should I specify when the project requires low-emitting materials?
The Pemko 211V carries a GREENGUARD Gold certified Eco-V insert, which is the one in the comparable group named for that certification, and the Pemko 209, 210 and 215 all use the Eco-V insert as well. The Cal-Royal DSR-406 pairs its aluminum channel with a flexible vinyl insert and adds the DSR rain drip. If the submittal is driven by an indoor air quality credit, the 211V is the shoe to put in front of the specifier; if it is driven by water deflection on a commercial entrance, the DSR-406 answers that directly.
15) Is the Cal-Royal DSR-406 door shoe made for commercial use or residential doors?
Commercial. Cal-Royal builds the DSR-406 for commercial door applications, and it turns up on office buildings, schools, healthcare facilities, retail, warehouse and industrial buildings, multi-tenant residential, and government work. On a multi-family property it fits the corridor and exterior entry doors, which are commercial-grade openings even in a residential building.
16) What is the difference between a vinyl door shoe and a neoprene one when standardizing across a building?
The Cal-Royal DSR-406 and the NGP 12T both run vinyl against an aluminum base, the DSR-406 as a flexible vinyl insert in an aluminum channel with a rain drip and the 12T as a thermoplastic shoe with a mill aluminum base and vinyl fins. The NGP 112 is the neoprene alternative in aluminum alloy, rated -20 F to 200 F. Standardizing a fleet of doors usually means picking one seal material and one profile height and holding to it, so decide whether the exposed openings dictate neoprene before you set the standard for the interior ones.
