NGP 613-36 – Frequently Asked Questions

1) Will the NGP 613 saddle threshold work under a standard commercial door opening at 6 inches wide?
The 613 is a flat saddle threshold measuring 6 inches wide by 1/4 inch tall, so it spans the full width of a typical commercial door jamb depth and sits only a quarter inch above the floor. That low 1/4 inch profile is what keeps it walkable and lets the door bottom clear it without undercutting the door. Measure your opening width first, then pick a length from 36, 42, 48, 60, 72, 74, 82, 84, 96, 108 or 120 inches and cut down to the exact jamb-to-jamb dimension.
2) What lengths does the NGP 613 threshold come in, and what do I order for a double door?
Eleven lengths are stocked: 36, 42, 48, 60, 72, 74, 82, 84, 96, 108 and 120 inches. For a single 36 inch door leaf the 36 inch piece is usually short once you account for jamb-to-jamb, so most installers step up and trim. For a pair of 36 inch leaves you are looking at roughly 72 to 74 inches of opening, which is why both those lengths exist. Order the next length up from your measured opening and cut to fit rather than trying to butt two pieces together at the centerline.
3) Does the NGP 613 come with fasteners, or do I need to order anchors separately?
Fasteners are in the box: #10 x 1-1/2 inch flat head zinc plated wood screws. Those are wood screws, so they land in a wood subfloor or a wood sill directly. If you are setting this on concrete you will need to add your own masonry anchors and drill the pilot holes, since the supplied screws will not hold in slab.
4) What is the closest alternative to the NGP 613 if I need the same 1/4 inch by 6 inch saddle?
The Pemko 272 Series is the direct cross for the same geometry, a flat saddle threshold at 1/4 inch x 6 inch in heavy-duty aluminum. If your specification calls out a fire rating instead, Cal-Royal's CR2000 Series saddle threshold is fire rated, and the CR3700 Series carries a 3-hour positive pressure fire rating. Match on the fire requirement first, because the 613's certification is a load rating, not a fire rating.
5) What is the closest equivalent to the NGP 613 saddle threshold from another manufacturer?
The Pemko 272 is the direct counterpart. It is a flat saddle threshold in heavy-duty aluminum at the same 1/4 inch height by 6 inch width as the NGP 613, so it drops into the same opening geometry with the same clearance under the door leaf. The NGP 613 carries a fluted top surface and is certified to ANSI/BHMA A156.21 with a 1,000 lb. load test rating, in aluminum alloy 6063 T5 temper; the Pemko 272 is described as ADA compliant. For a property manager standardizing entries across a building, either one keeps the 1/4 inch rise consistent from door to door.
6) Is the top of the NGP 613 threshold slippery when wet?
The top face is fluted, meaning a textured ribbed surface that gives traction underfoot. For wetter or higher-risk locations NGP offers an SIA slip-resistant finish on this threshold as an option, so a building entry or a locker room corridor can be specified with the abrasive surface instead of plain mill aluminum.
7) Should I use a flat saddle threshold or a thermal break / interlocking type for my opening?
A saddle like the 613 is the flat plate type, a simple ramp-free crossing that levels a small floor height change and gives the door bottom something to seal against. It carries no gasket, no thermal break and no rain drip, so it belongs on interior openings, vestibule doors and exterior doors where a separate sweep and weatherstrip handle the sealing. If your door needs an integral seal cavity, a rain lip, or a thermal break for an exterior aluminum entrance, a saddle plate is the wrong type and you want a thermal or bumper-seal threshold instead.
8) Can the NGP 613 aluminum threshold be cut down on site?
Yes. It is a 6063-T5 aluminum extrusion with a 0.125 inch typical wall, which cuts cleanly with a carbide blade on a chop saw, so ordering the next length up and trimming to the measured opening is the normal way it goes in. Drill fastener holes after cutting so the screw spacing lands where you want it in the sill.
9) What is the difference between the Cal-Royal CR2000 and the CR3700 saddle thresholds?
Both are Cal-Royal saddle thresholds, but they are written to different fire criteria. The CR2000 belongs to the CR 2000 Series and is described as fire rated and ADA compliant. The CR3700 belongs to the CR 3700 Series and carries a 3-hour positive pressure fire rating, which is the specific callout on drawings for openings tested under positive pressure conditions. A general contractor matching a submittal should read which of the two the architect named rather than treating the Cal-Royal saddle thresholds as one item.
10) Can a Pemko 272 be swapped in where an NGP 613 was pulled out without redrilling or reworking the sill?
The profiles match on the two dimensions that decide it. The Pemko 272 is a flat saddle threshold at 1/4 inch by 6 inch in heavy-duty aluminum, and the NGP 613 is a 6 inch wide by 1/4 inch tall aluminum saddle, so the sill footprint and the rise under the door are the same and the door bottom clearance does not change. The surfaces differ: the NGP 613 has a fluted top for traction, with an SIA slip-resistant finish offered, while the 272 is a flat saddle. Anchor holes are field drilled on a threshold replacement either way, and the NGP 613 ships with #10 x 1-1/2 inch flat head zinc plated wood screws.
11) What finish is the NGP 613 saddle threshold, and can I match it to other openings in my building?
Mill aluminum, which is the raw unfinished extrusion color, a plain silver-grey. That is the standard threshold finish across most commercial buildings, so it will read the same as existing aluminum saddles and aluminum door frames on your other openings. It is 6063-T5 alloy, so it holds up against corrosion in exterior and vestibule locations without a coating.
12) Which saddle threshold covers long openings like storefront or double doors in one piece?
The NGP 613 is stocked in lengths from 36 inches up through 96, 108 and 120 inches, so a pair of doors or a wide storefront opening can be crossed on a single continuous piece instead of a butted joint at mid-opening. It is an aluminum alloy 6063 T5 saddle at 0.88 lbs. per foot, which keeps a 10 foot piece manageable to set. Cal-Royal offers the CR2000 and CR3700 saddle thresholds and Pemko the 272 flat saddle for the same class of opening; a glass front installer sizing a wide entry should confirm the run length before choosing between them.
