NGP 223SA-36 – Frequently Asked Questions

1) Will the NGP 223S automatic door bottom work on a door that needs low operating force for accessibility?
Activation takes only 3 to 5 pounds of pressure on the EZ-Touch plunger, which is why it gets specified on openings where door operating force is being kept down. The seal drops up to 3/4 inch when the door closes and retracts when it opens, so the door isn't dragging a sweep across the floor the rest of the time.
2) How much gap under the door can the NGP 223S EZ-Touch door bottom close?
Up to 3/4 inch. That is the maximum drop of the seal, measured from the retracted position, so an undercut larger than 3/4 inch will not be sealed by this unit. Measure the worst point of the sill, not the best one, since a floor that slopes toward the strike side is where the gap runs biggest.
3) What length NGP 223S do I order for a 36 inch door?
Order the 36 inch unit for a standard 3-0 door and the 48 inch for a 4-0. The 223S is a cut-to-fit extrusion and can be shortened to as little as 23-1/4 inch net length, so on a narrower leaf you buy the next size up and trim it. Cut the aluminum housing and the silicone seal, not the plunger end.
4) Is the Pemko SA Series a direct equivalent to the NGP 223S automatic door bottom?
They are the closest peers to each other: the Pemko SA Series is an automatic door bottom and so is the NGP 223S, both surface applied to the face of the door rather than mortised into it. The differences are in seal material and length. The 223S uses a siloxane closed cell sponge seal rated from -100 F to 500 F with a 3/4 inch maximum drop, and comes in 36 inch and 48 inch lengths in anodized aluminum, gold, or dark bronze. The Pemko SA Series carries a GREENGUARD Gold certified Eco-V insert and is offered here at 36 inches. For a spec calling for a low emitting material or a green building submittal, the Eco-V insert on the SA Series is the one that answers it; for extreme heat or cold at the opening, the silicone seal on the 223S is the one rated for it.
5) I need a 48 inch automatic door bottom for a wide commercial opening - what are my options?
The NGP 223S EZ-Touch automatic door bottom is offered at 48 inches as well as 36 inches, in anodized aluminum, gold, and dark bronze, with a 3/4 inch maximum drop and 3 to 5 pounds of activation pressure. The Pemko SA Series surface mount automatic door bottom is an equivalent automatic type but is carried at 36 inches, so for a 48 inch leaf the 223S is the one that covers the width without splicing.
6) Is the NGP 223S surface mounted or does it get mortised into the bottom of the door?
The 223S is the surface applied version of the EZ-Touch automatic door bottom, so it screws to the face of the door at the bottom rail and needs no routing. That matters on a retrofit: you can add it to an existing hollow metal or wood door without pulling the leaf and running it through a shop. It ships with standard end caps for a finished look at both ends.
7) Will a silicone automatic door bottom hold up in a boiler room or a commercial kitchen?
The siloxane closed cell sponge seal is rated from -100 F to 500 F and stays flexible at both ends of that range, so mechanical rooms, kitchen back-of-house, and freezer vestibules are all inside its window. The seal also resists ozone, UV, and aging, which is what usually kills a vinyl or neoprene sweep in a few seasons.
8) What door bottom should I use in a room protected by FM200 or Halon fire suppression?
NGP recommends the silicone-sealed EZ-Touch bottom for rooms on FM200 or Halon systems. Those systems only hold concentration if the enclosure is tight, and the siloxane seal is flame resistant and moisture resistant rather than a plain vinyl bulb. Data rooms and electrical closets are the usual application.
9) Is there another surface mount automatic door bottom besides the NGP EZ-Touch?
Pemko's SA Series is the closest cross-brand equivalent ZenSupply carries, also a 36 inch surface mount automatic door bottom, with a GREENGUARD Gold certified Eco-V insert. If a project is chasing low-emitting material credits, that insert certification is the deciding difference. If the driver is temperature extremes or a clean-agent suppression room, the NGP 223S silicone seal is the one to spec.
10) What is the simplest way to seal the bottom of a commercial door without a mechanical automatic door bottom?
A fixed sweep. The Pemko 345 Series door bottom sweep carries a PemkoPrene insert and a rain drip and has no drop mechanism, actuator, or plunger to adjust or service; it fastens to the door face and the insert stays in contact with the floor. The NGP 223S takes the other approach, with an aluminum alloy 6063 T5 housing and a siloxane seal that drops 3/4 inch on closing and retracts on opening, which is what you want when the seal cannot be allowed to drag over finish flooring or a raised threshold. On a utility, mechanical, or exterior service door where drag does not matter, the fixed sweep does the same sealing job with fewer moving parts.
11) Which door bottom should I use on an exterior door that takes driving rain?
Look at the Pemko 345 Series sweep first. It is a door bottom sweep with a rain drip built in, which throws water off the face of the door away from the bottom seal, and a PemkoPrene insert. The NGP 223S automatic door bottom uses a siloxane closed cell sponge seal that resists ozone, UV, moisture, and aging and drops 3/4 inch when the door closes, and it is the better answer for a heated or cooled opening where the seal has to retract, including areas served by FM200 or Halon fire suppression systems. For a rain-loaded exterior opening specifically, the rain drip on the 345 is the feature that addresses the water.
12) Does a door bottom sweep do the same job as an automatic door bottom for accessibility openings?
Not the same way. A fixed sweep such as the Pemko 345 Series keeps its PemkoPrene insert against the floor through the whole swing, so whatever drag it creates is added to the force needed to operate the door. The NGP 223S automatic door bottom stays retracted while the door swings and is driven down only at the last of the closing travel, and its EZ-Touch mechanism needs just 3 to 5 pounds of pressure to actuate, which is why it is the type specified where opening force at the door matters. If the opening is being reviewed for accessible operating force, the automatic bottom and the fixed sweep are not interchangeable.
13) What finishes does the NGP 223S EZ-Touch door bottom come in?
Three: anodized aluminum, gold, and dark bronze, and all three are offered in both the 36 inch and 48 inch lengths. Dark bronze is the usual match on bronze-anodized aluminum entrances, gold on brass-toned hardware sets, and mill anodized aluminum on hollow metal painted openings where the housing should disappear against the door bottom.
14) Is the NGP 223S aluminum housing strong enough for a high-traffic commercial entry?
The housing is 6063 T5 aluminum extrusion, the standard temper for architectural door gasketing, and the 223S is a commercial-rated product rather than a residential sweep. It goes into offices, schools, hospitals, retail, warehouses, and government buildings. On a door cycling hundreds of times a day the wear point is the seal, not the housing, and the closed cell siloxane has memory so it recovers its shape between cycles.
