NGP 99T6DKB-36 – Frequently Asked Questions

1) What lengths does the NGP 99T6DKB door shoe come in, and can I cut it down to fit my door?
The NGP 99T6DKB extended door shoe is offered in 36 inch and 48 inch lengths, with 48 inches the longest it runs. Aluminum alloy 6063-T5 extrusion cuts cleanly with a miter saw or hacksaw, so a 36 inch door leaf takes the 36 inch piece trimmed to the leaf width. For an opening wider than 48 inches, this shoe won't cover it in one piece.
2) Does this NGP door shoe carry a fire rating for a labeled opening?
Treat the 99T6DKB as a general commercial door bottom seal. If your opening carries a fire label and the gasketing has to be listed, a shoe sold specifically as fire rated is the safer specification, such as the Pemko 210 fire-rated door bottom shoe with Eco-V insert or the Pemko 215, which is described as UL10C certified with a rain drip.
3) The NGP 99T6DKB has no rain drip. What door shoe should I use on an exterior door that takes weather?
The NGP 99T6DKB is an extended shoe with a thermoplastic insert and no drip feature. For an exterior opening where water runs down the face of the door, Pemko builds a rain drip into two of its shoes: the 211V is an L-shaped door shoe with rain drip and a GREENGUARD Gold certified Eco-V insert, and the 215 is a fire-rated door shoe with rain drip and Eco-V insert. The drip throws water clear of the threshold instead of letting it track under the door.
4) Is the NGP 99T6DKB door shoe fire rated, and what should I use on a fire-rated opening instead?
The NGP 99T6DKB is described as flame resistant and moisture resistant, but for an opening where the drawing calls out a fire-rated door bottom shoe, Pemko offers shoes carrying that designation directly: the 210 is a fire-rated door bottom shoe with Eco-V insert in 36 inch aluminum construction, and the 215 is a fire-rated door shoe with rain drip and Eco-V insert that is UL10C certified. If an inspector will be checking the label on a rated assembly, specify one of those.
5) Do I need to buy screws separately for the NGP 99T6DKB door shoe?
No. The shoe ships with #6 x 3/4 inch stainless steel sheet metal screws, so mounting hardware is covered. Stainless is the right call on an exterior bottom rail where the fastener heads sit in the wet zone. End caps, if you want a finished look on the ends, are a separate item.
6) Is a door shoe or a door sweep the right part for sealing the bottom of my commercial door?
A door shoe like the NGP 99T6DKB wraps the bottom edge of the door leaf and carries the thermoplastic seal in an extruded aluminum channel, so it protects the bottom rail as well as sealing to the threshold. A surface-applied sweep only screws to the face of the door and leaves the bottom edge exposed. Choose the shoe when the door bottom takes weather or wash-down, and when you want the seal replaceable without taking the extrusion off.
7) Will the NGP 99T6DKB hold up in an unheated warehouse or on an exterior door in winter?
The seal is rated to work from 0 F to 140 F, which covers an unheated warehouse, a loading dock door, or a summer exterior opening in most of the country. The insert is PVC-based with a bio-based plasticizer and is flame and moisture resistant; the 6063-T5 aluminum body resists corrosion. Below 0 F, look at a different gasket.
8) What are the alternatives if I want a basic aluminum door shoe with a vinyl insert instead of this NGP?
The closest straight substitute in the same plain aluminum-and-vinyl category is the Cal-Royal DS-403 aluminum door shoe with vinyl insert. The Pemko 209 with Eco-V vinyl insert is another, in a 1/2 inch by 1-3/8 inch profile if you need that specific section to clear existing hardware on the bottom rail.
9) I need a door shoe for a LEED or low-emitting materials submittal. How does the NGP 99T6DKB compare?
The NGP 99T6DKB uses a PVC thermoplastic insert formulated with a bio-based plasticizer, which is the sustainability angle it carries. If the submittal specifically wants a third-party certification on the gasket material, the Pemko 211V carries a GREENGUARD Gold certified Eco-V insert, which is the documented certification in this group. Both are aluminum-bodied shoes that install the same way on the door bottom.
10) My door is 36 inches wide. Do I need the 48 inch NGP 99T6DKB or is there a 36 inch option?
The NGP 99T6DKB extended door shoe is offered in both 36 inch and 48 inch lengths, so a standard 3-0 door takes the 36 inch. Among the comparable shoes, the Pemko 210 fire-rated door bottom shoe is likewise built in 36 inch aluminum. Longer stock is cut to fit; the 48 inch NGP length is there for wider leaves or pairs.
11) Will the dark bronze finish on this NGP door shoe match my existing bronze storefront and hinges?
The 99T6DKB is finished dark bronze, which is the standard companion to dark bronze anodized aluminum storefront, thresholds and other NGP gasketing. If the rest of the opening is mill aluminum or clear anodized, the bronze will read as a deliberate contrast at the door bottom rather than a match.
12) Can I reuse the NGP 99T6DKB aluminum extrusion and just replace the seal when it wears out?
Yes, that's how the part is built. The thermoplastic insert is a separate component held in the 6063-T5 aluminum channel, so when the seal flattens or tears from traffic you pull the insert and fit a new one without unscrewing the extrusion from the door. That matters most on high-cycle openings in schools, healthcare and multi-tenant buildings.
13) Is an L-shaped door shoe the same thing as the NGP 99T6DKB?
Not quite. The NGP 99T6DKB is an extended door shoe with a thermoplastic insert, mounting to the face of the door. The Pemko 211V is an L-shaped door shoe, a different section that wraps the bottom edge and adds a rain drip. They serve the same purpose of sealing the door bottom but they are not interchangeable sections, so confirm which profile the existing hardware or the spec calls for before ordering a replacement.
