NGP 2V-36 – Frequently Asked Questions

1) What does a stop strip like the NGP 2 Series actually do at a door opening?
The NGP 2 Series is an extruded aluminum strip that mounts at the door stop and carries a bumper seal, closing the gap between the stop and a saddle threshold so the opening has one continuous seal line. It is not a threshold itself, it is the accessory that finishes a saddle threshold at the stop. If you need the piece the door swings over on the floor, you want a saddle threshold, not this.
2) How big is the NGP 2 stop strip profile, and will it fit under my existing door clearance?
The profile runs 3/8 inch high by 1/2 inch wide, so it adds a half inch of depth on the stop face and stands 3/8 inch off it. On a typical commercial opening that sits in the rabbet without interfering with the door face, but measure your stop depth first if the frame is a shallow or non-standard rabbet. Weight is 0.16 lbs per foot, so it hangs on #6 screws without any reinforcement.
3) Vinyl, TPV, or silicone bumper on a stop strip: which seal should I order?
All three are offered on the NGP 2 Series and they differ in service conditions. Vinyl (V) is the standard commercial choice for interior and protected exterior openings. NGP-TPV (N) is the thermoplastic vulcanizate option, which holds flexibility better in cold. Silicone (S) is the one to specify where the opening sees heat or wide temperature swings, since silicone keeps its set across the widest range. Match the seal to your threshold system and the performance you need at that opening.
4) Will the NGP 2 stop strip fit my existing NGP saddle threshold, or do I have to modify it?
The 2 Series is built to integrate with NGP saddle threshold systems, so it lands as a matched fit against those without field modification. Against another manufacturer's saddle it will still mount, since it fastens to the stop rather than to the threshold, but the seal line at the sill is where you should check the fit before committing to a whole building's worth.
5) What lengths does the NGP 2 stop strip come in, and how do I cover a pair of doors or a taller frame?
Two lengths are stocked, 36 inch and 48 inch. Aluminum 6063 in T5 temper cuts cleanly with a miter saw and a non-ferrous blade, so a run is normally cut to the measured stop length on site. For a pair of doors you are covering two jamb legs plus the head, so count each leg separately rather than assuming one piece spans the opening.
6) Does the NGP 2 stop strip come with fasteners, or do I need to buy screws?
#6 self-tapping machine screws ship with it, so no separate fastener order is needed for a standard hollow metal or aluminum jamb. Self-tappers mean you drill a pilot and drive, no anchors. If you are mounting into a wood jamb you may prefer your own wood screws in the same #6 size.
7) Can I get the stop strip in Dark Bronze to match the rest of my door hardware?
Mill Aluminum and Dark Bronze are both stocked, and every bumper seal option is available in each. So a Dark Bronze strip with a silicone bumper in 48 inch is an orderable combination, as is any other mix of the three seals, two finishes, and two lengths. Mill matches clear anodized aluminum frames; Dark Bronze is the one to pick against bronze anodized storefront.
8) Is aluminum 6063-T5 good enough for an exterior entrance that gets weather?
6063 in T5 temper is the standard architectural extrusion alloy and it resists corrosion well in exterior door openings, which is why it is used for storefront framing and thresholds. The T5 temper holds the extruded profile dimension so the bumper seat does not distort over time. For a coastal or heavy chemical environment, the Dark Bronze finish adds a coating layer over the bare alloy.
9) I manage a portfolio and want one stop strip across all my entries. Is this a commercial-duty part?
Yes, the 2 Series is specified as commercial rather than residential, and it is used on office and retail entries, schools and healthcare, government and municipal buildings, multi-family and hospitality, and industrial or warehouse entry doors. Standardizing is straightforward: pick one finish and one bumper seal, then order 36 or 48 inch to suit each opening.
