Pemko 307APK 36 – Frequently Asked Questions

1) Will the Pemko 307 door bottom sweep work on a fire rated door?
Yes. The Pemko 307 door bottom is Fire Rated to UL 10C and Smoke Tested to UL 1784, so it can go on a rated opening. That combination is what an inspector looks for on a labeled door: UL 10C covers the fire test, UL 1784 covers air leakage past the assembly. It is also GREENGUARD Gold Certified, which matters on schools and healthcare jobs with indoor air quality requirements.
2) How much clearance under the door do I need for a Pemko 307 sweep?
The 307 is a surface applied sweep with a profile measuring 1-7/8 by 1/4 inches, mounted to the face of the door near the bottom rail. The 1/4 inch is the depth it stands off the door face, so it needs a clear swing path over the threshold rather than a large undercut. The PemkoPrene insert bridges the gap between the door bottom and the floor or threshold, so measure your actual undercut before ordering to be sure the insert reaches without dragging.
3) What is the closest equivalent to a Pemko 307 door bottom sweep from another brand?
The Cal-Royal BTN-112 door bottom sweep is the nearest match in construction: it uses an extruded aluminum retainer with a neoprene insert, the same surface-plate-plus-flexible-insert arrangement as the Pemko 307, which pairs an aluminum substrate with a PemkoPrene insert. The NGP 197NA neoprene door sweep with an anodized aluminum housing is the other close counterpart. All three mount to the face of the door bottom and seal against the threshold with a flexible strip carried in an aluminum carrier. The difference is the insert compound: PemkoPrene on the 307 versus neoprene on the BTN-112 and the 197NA.
4) Which door sweep should I use instead of a Pemko 307 on a high heat or freezer door?
Use the NGP 200SA silicone door sweep with an anodized aluminum housing, which is rated for a temperature range of -100 F to 500 F. The Pemko 307 carries a PemkoPrene insert selected for chemical resistance to cleaning fluids and disinfectants, which is what makes it a healthcare and institutional seal; the 200SA silicone insert is the one specified by temperature. If the opening is a boiler room, kitchen line, or walk-in cooler, specify the 200SA and keep the 307 for interior corridor and office openings.
5) What is PemkoPrene and how is it different from a vinyl or neoprene door sweep insert?
PemkoPrene is a rubber-like insert material that combines the flexibility of natural rubber with thermoplastic processing. On the 307 it is a 1 inch insert carried in an aluminum retainer. Practically, it stays pliable and resists cleaning fluids and disinfectants, which is why it turns up on healthcare and institutional jobs where floors get mopped with harsh chemicals daily. A vinyl insert like the one on the NGP 101V is the more basic option; a neoprene insert like the NGP 197NA is the traditional commercial rubber. If you need extreme temperature range instead of chemical resistance, the NGP 200SA is a silicone sweep rated from -100 F to 500 F.
6) Is the Pemko 307 sweep suitable for a hospital or school door that gets cleaned with disinfectants?
That is one of the cases the PemkoPrene insert is built for. It resists cleaning fluids and disinfectants, so daily mopping and wipe-downs at the door bottom will not break it down the way some inserts do. Add the GREENGUARD Gold certification for indoor air quality and the UL 10C fire rating for rated corridor doors, and it covers what most healthcare and education facility specs are asking for at the door bottom.
7) What is the difference between a door bottom sweep and a door shoe?
A sweep like the Pemko 307 surface mounts to the face of the door near the bottom and its insert reaches down to the floor or threshold. A door shoe wraps the bottom edge of the door itself. The 307 is the surface plate type, which means you can install it on an existing hung door without pulling the door off the hinges, and you can adjust the height at install by where you set the plate. That is usually the faster retrofit on an occupied building.
8) I need to replace a worn out neoprene door sweep on a rated door. Can I use the Pemko 307?
Yes, provided the door bottom clearance suits it. The 307 is a face-mounted aluminum sweep at 1-7/8 by 1/4 inches with a 1 inch insert, and it carries UL 10C and UL 1784, so it holds the rating on a labeled door. Compared to a straight neoprene replacement such as the NGP 197NA, you are swapping to PemkoPrene, which adds the chemical resistance. If the existing sweep's mounting holes do not line up you will drill new ones, so plan on fresh fasteners rather than reusing the old pattern.
9) What is the difference between a vinyl door sweep and the Pemko 307 PemkoPrene sweep?
The NGP 101V is a vinyl door sweep in an aluminum alloy housing; the Pemko 307 uses a PemkoPrene insert, a rubber-like material that combines the flexibility and durability of natural rubber with thermoplastic processing advantages, in an aluminum surface plate measuring H 1-7/8 inch by W 1/4 inch. Vinyl is the plainer weatherstrip compound and is common on exterior and utility openings. PemkoPrene is the one to specify where the sweep will be washed down repeatedly, because the 307 is built for resistance to cleaning fluids and disinfectants in healthcare and institutional buildings, and it is GREENGUARD Gold certified for indoor air quality on projects that track it.
10) Does the Pemko 307 come in a painted or anodized finish, or just mill aluminum?
The 307 as stocked is an aluminum sweep in Mill Finish Aluminum, in the 36 inch length. Mill finish is the raw, unfinished aluminum look. If the job calls for a darker or anodized housing to match dark bronze or black frames, the NGP 197NA and NGP 200SA both use an anodized aluminum housing.
11) Will a surface mounted door sweep make the door harder to open or close?
The 307 is built for low operating force, so the insert gives minimal resistance as the door swings. That matters where doors are on closers with a set closing force, and on openings where an accessible opening force has to be maintained. The insert makes contact and seals without loading the door up the way an over-tight seal does.
12) Is the Pemko 307 rated for commercial use or is it a residential weatherstrip?
Commercial. The 307 is an aluminum substrate sweep with a fire and smoke rated listing, intended for commercial door hardware use rather than residential weatherstripping. It shows up on office buildings, healthcare, schools, retail, warehouse, multi-tenant residential, and municipal work.
13) Can I mix a Cal-Royal BTN-112 and a Pemko 307 on doors in the same building?
Both are surface-applied door bottom sweeps that fasten to the face of the door and seal down to the floor, so either one will work on a standard flat-bottom commercial door. The Cal-Royal BTN-112 uses an extruded aluminum retainer with a neoprene insert; the Pemko 307 uses an aluminum substrate with a PemkoPrene insert on a 1-7/8 inch high by 1/4 inch wide profile in a mill finish aluminum. Where they differ visibly is the retainer profile and finish, so on doors facing each other in the same corridor, run one part number for a matched look and keep the other for back-of-house.
14) Which neoprene door sweep is comparable to the Pemko 307 for an exterior opening?
The NGP 197NA neoprene door sweep with an anodized aluminum housing is the neoprene counterpart. Neoprene and the PemkoPrene insert on the Pemko 307 are both flexible rubber-type strips carried in an aluminum housing, and both install to the door face. The 197NA housing is anodized; the 307 comes in a mill finish aluminum with a 1-7/8 inch high by 1/4 inch wide profile in a 36 inch length. Specify by the housing finish you want at the opening and by the door width you are covering.
