Cal-Royal CR270436-ALUM – Frequently Asked Questions

1) Will the Cal-Royal CR2000 saddle threshold work on a 3-hour fire rated door opening?
Yes. The CR2000 saddle threshold carries a 3-Hr Positive Pressure fire rating and is UL 10B and UL 10C Listed, plus UBC 7-2 (1997) compliant. That covers the positive pressure test standards inspectors look for on fire rated assemblies, so it can go under a fire door in a stair enclosure, corridor, or exit passageway without knocking out the assembly's rating.
2) Can I get a CR2000 threshold long enough for a pair of doors?
Lengths run 36, 48, 72 and 96 inches, and all four lengths are offered in each of the four widths. A single 36 inch covers a standard 3-0 door; the 72 and 96 inch pieces are the ones for pairs of doors or wide storefront openings, so you span the full opening with one continuous piece instead of butting two thresholds under a mullion. Aluminum and Duronodic are both available in every length.
3) What screws do I need to install a Cal-Royal CR2000 threshold, and do they come with it?
Fastening is #10 x 1-1/2 inch wood screws, and the screws ship matched to the finish: zinc plated with MIL finish, brass with brass, matching plated screws with color anodized, and stainless with stainless steel thresholds. Note that those are wood screws. If you are anchoring into a concrete slab, which is most commercial exterior openings, you supply your own masonry anchors and sleeves in the #10 range instead. Budget for that on the job or you will be stopped at the door.
4) I have a step or a floor height difference at the door - is the Cal-Royal CR2000 the right threshold?
The Cal-Royal CR2000 is a flat saddle threshold at a uniform 1/2 inch height, designed as a barrier-free transition over carpet rather than a way to bridge two floor levels. For an opening where the interior and exterior floors sit at different heights, an offset threshold is the correct part: the NGP 653 is an offset threshold 1/2 inch by 5-1/2 inches in aluminum alloy, with a stepped profile that lands on two planes instead of one. Confirm the actual height difference at the sill before ordering either.
5) Should I use a saddle threshold like the CR2000 or an offset threshold?
A saddle is symmetrical, flat topped and sits centered under the door, so it works when the finished floor is at roughly the same height on both sides and you just need a clean transition and a stop for the door bottom sweep. An offset threshold steps down on one side and is the choice when there is a real height difference between the two floors, or when you need the door to close against a raised lip on the interior side. If your two floors are level, the CR2000 saddle is the simpler part. If you have a step, look at an offset design such as the NGP 653 Offset Threshold instead.
6) I need to standardize thresholds across a whole building. Is the CR2000 the right choice for a school or hospital?
It fits that use. The CR2000 is a commercial-rated heavy-duty saddle carrying the 3-Hr Positive Pressure rating with UL 10B, UL 10C and UBC 7-2 (1997), which is what an institutional spec asks for on rated corridor and stair doors, and the same profile is barrier free over carpet for the non-rated openings. Because one 1/2 inch height runs across all four widths, you can hold a single height standard building-wide and vary only the width to suit each opening, which keeps the sweep and door bottom hardware consistent too.
7) Will a 1/2 inch high threshold leave a gap under my door?
It does the opposite. At 1/2 inch, the CR2000 raises the floor line under the door, so the undercut you have to seal drops by that half inch. On a fire rated or smoke rated opening you still pair it with a door bottom sweep or automatic door bottom that seats onto the top of the saddle. Set the door bottom clearance off the finished threshold surface, not the slab, or you will cut the sweep short.
8) My spec calls for a BHMA certified threshold - does the Cal-Royal CR2000 meet that, or should I look at another part?
If the drawing calls out BHMA certification specifically, the NGP 1013 saddle threshold is BHMA certified and comes as a 1/4 inch by 10 inch mill aluminum saddle. The Cal-Royal CR2000 is certified on a different set of standards: UL 10B and UL 10C listed, UBC 7-2 (1997) compliant, 3-Hr Positive Pressure fire rated, and barrier free over carpet for ADA transitions. On a rated opening where the submittal is written around UL 10C and positive pressure, the CR2000 is the one that answers the spec; where the submittal names BHMA, order to that.
9) I am standardizing thresholds across a facility in a dark finish - which of these can I order that way?
The Cal-Royal CR2000 saddle thresholds come in Aluminum and Duronodic across all four widths - CR2704 at 4 inches, CR2715 at 5 inches, CR27105 at 6 inches and CR2767 at 7 inches - and in 36, 48, 72 and 96 inch lengths, so one series covers a mix of door widths in a consistent dark bronze look. The NGP 1013 saddle threshold is a mill aluminum part, so it will read as bright aluminum alongside a Duronodic run.
