NGP 137NA-36 – Frequently Asked Questions

1) Will one NGP 137NA perimeter seal cover a standard commercial door frame, or do I need more than one piece?
Plan on more than one piece per opening. The 137NA neoprene bulb perimeter seal comes in 36 inch and 96 inch lengths, and a perimeter seal runs the head and both jambs. A typical single opening takes one 36 inch piece across the head and two 96 inch pieces down the jambs, cut to fit. For a pair of doors, double the head coverage. Order by the lineal footage of the frame, not by the door count.
2) Will a neoprene bulb seal hold up on an unheated warehouse or a hot south-facing entrance?
Yes, across both extremes. The 137NA bulb is a synthetic rubber blend of chloroprene and EPDM rated from -20 F to 200 F, and it is BHMA certified to the ANSI/BHMA A156.22 heat and cold performance tests. That covers a cold loading dock in winter and a dark metal door baking in afternoon sun. EPDM in the blend is what gives it the ozone, sunlight, and aging resistance an exterior opening needs.
3) Will the NGP 137NA perimeter seal stop drafts under the door too?
No. The 137NA is a perimeter seal, so it handles the head and the two jambs only. The bottom of the door is a separate part: you need a door bottom, a door shoe, or an automatic door bottom, plus a threshold if the opening does not already have one. Buyers often order the perimeter seal expecting it to complete the opening and then come back for the sweep.
4) What is a cross-brand equivalent to the NGP 137NA perimeter seal?
The Cal-Royal PG-601 aluminum channel perimeter gasketing is the closest cross-brand counterpart. Both are aluminum-channel perimeter gasketing that mounts to the frame stop to seal the head and jambs of a commercial door. The difference is the sealing element: the NGP 137NA carries a neoprene bulb in a synthetic rubber polymer blend of Chloroprene and EPDM, while the PG-601 uses a vinyl insert. If a facility standard calls out neoprene rather than vinyl, the 137NA is the one that meets it; if the spec is silent on the sealing material and only calls for aluminum channel perimeter gasketing, either fills the opening.
5) Neoprene bulb or vinyl insert perimeter gasketing - which material should I use on an exterior door that sees hard freezes and summer heat?
Choose by the published temperature rating. The NGP 137NA neoprene bulb seal is rated for -20 F to 200 F and is BHMA certified to the ANSI/BHMA A156.22 performance tests for heat and cold, which is the certification an institutional or MRO buyer looks for when the opening swings through both extremes. The Cal-Royal PG-601 seals with a vinyl insert in an aluminum channel instead of a neoprene bulb. For an exterior entrance where the seal has to stay compliant and keep its memory through freeze and heat cycles, the 137NA is the one carrying the heat-and-cold certification.
6) Does the NGP 137NA weatherstrip come with fasteners, or do I need to supply screws?
Screws are in the box. The 137NA ships with #6 x 3/4 inch stainless steel sheet metal screws, and the aluminum carrier has slotted holes so you can shift the strip against the door face before you tighten down. Stainless fasteners matter on an exterior opening, since plain steel screws will bleed rust down an anodized jamb.
7) Is the NGP 137NA rated for commercial openings or is it residential weatherstripping?
Commercial. The 137NA is built on a 6063 T5 aluminum extrusion rather than a vinyl or foam carrier, and it carries BHMA certification to ANSI/BHMA A156.22. For an MRO or institutional buyer standardizing weatherstrip across a facility, that A156.22 certification is the line item a spec usually calls out, and 6063 T5 is the same alloy and temper used for commercial storefront trim.
8) What is the difference between a neoprene bulb perimeter seal and a vinyl insert gasket?
The seal element is the difference. The NGP 137NA uses a hollow neoprene bulb that compresses against the door face and springs back, with the chloroprene and EPDM blend giving it memory and abrasion resistance over repeated cycles. A vinyl insert type, like the Cal-Royal PG-601 aluminum channel perimeter gasketing, uses a vinyl strip carried in an aluminum channel. Both mount to the frame the same way. A bulb generally suits an opening where the door does not close perfectly flat to the stop, because the bulb takes up more variation in the gap than a flatter insert does.
9) Does the NGP 137NA mount to the door frame or to the door itself?
To the frame, on the stop. The 137NA aluminum carrier screws to the door stop so the black neoprene bulb sits against the face of the door and compresses when it closes. The slotted screw holes let you set how hard the bulb bears on the door, which is how you tune out a rattle or a light gap without redrilling. Mounting to the stop is also why handing doesn't matter on this part.
10) I need to seal the bottom of the door, not the jambs - is the Cal-Royal PG-601 or the NGP 137NA the right part?
Neither. Both the NGP 137NA and the Cal-Royal PG-601 are perimeter gasketing, meaning they mount on the frame at the head and jambs to seal where the door face meets the stop. The bottom of the door is a different part entirely - a door bottom or door shoe that attaches to the door leaf itself, or a threshold seal at the floor. A common mistake on a weatherstripping takeoff is ordering perimeter gasketing for all four sides of the opening; order the 137NA or PG-601 for the head and two jambs, and specify a door bottom separately for the sweep line.
11) The frame is an odd size and 96 inches is more stock than I need per opening - what are my options between the NGP 137NA and the Cal-Royal PG-601?
The NGP 137NA comes in a 36 inch length as well as the 96 inch, so a jamb-height run and a head run can be ordered closer to finished size instead of cutting down long stock. The 137NA also has slotted screw holes, which let the piece be shifted for alignment after it is set against the stop rather than committing to the first hole position. The Cal-Royal PG-601 is aluminum channel perimeter gasketing with a vinyl insert. For a contractor doing a handful of openings at a non-standard height, the shorter 137NA run reduces the offcut per door.
12) Will anodized aluminum weatherstripping match aluminum storefront doors already in the building?
Generally yes. The 137NA carrier is anodized aluminum with a black neoprene bulb, which reads as a clean mill or clear anodized line against aluminum storefront and hollow metal frames. Property managers replacing gasket on some openings but not all usually find the anodized carrier blends with existing aluminum frame trim better than a painted or bronze strip would.
13) Is neoprene perimeter gasketing acceptable on a door in a healthcare or school corridor?
The 137NA is specified for commercial use and is flame resistant and moisture resistant, with BHMA certification to ANSI/BHMA A156.22. NGP lists it for educational facility exterior doors and healthcare climate control among its applications. For a fire rated opening, the gasketing on the door has to be part of a listed assembly, so confirm the opening's fire requirements against the door and frame labels before committing a facility-wide standard.
