Cal-Royal CR372636-AL – Frequently Asked Questions

1) Can I use the CR3726 on a fire-rated door opening?
Yes. The CR3726 carries a 3-Hr Positive Pressure rating and is UL 10B and UL 10C Listed, plus UBC 7-2 (1997) compliant, so it can go under a fire-rated door assembly up to that rating.
2) What lengths does the Cal-Royal CR3726 saddle threshold come in?
Four lengths: 36, 48, 72 and 96 inches. The 36 inch covers a standard single 3-0 door, 48 inch gives you cutting room or suits a wider leaf, and the 72 and 96 inch lengths run continuously across a pair of doors or a door with a sidelite. Both the Aluminum and DURO (dark bronze) finishes are offered in all four lengths.
3) I need a 6 inch wide flat saddle threshold - what else do you carry besides the Cal-Royal CR3726?
The Pemko 272 Series flat saddle threshold is the closest match, also a 1/4 inch by 6 inch heavy-duty aluminum saddle and ADA compliant. If the 6 inch width is not deep enough for your frame condition, the NGP 1013 is a 1/4 inch by 10 inch mill aluminum saddle. Both are alternatives on width, not on the CR3726's fire rating.
4) My door has a finished floor on one side that is higher than the other - is a flat saddle like the CR3726 the right choice?
No. A flat saddle such as the CR3726 sits level and is for transitions where the two floor levels are essentially the same. For a height change, use an offset threshold: the NGP 653 is a 1/2 inch by 5-1/2 inch aluminum alloy offset saddle designed for that condition.
5) What is the closest equivalent to the Cal-Royal CR3726 saddle threshold from another manufacturer?
The Pemko 272 Series flat saddle threshold shares the same 1/4 inch height by 6 inch width aluminum saddle profile as the Cal-Royal CR3726 and is described as ADA compliant heavy-duty aluminum. Both are flat saddle thresholds intended for commercial openings, so the 6 inch width will cover the same frame footprint. The CR3726 additionally carries a 3-Hr Positive Pressure rating with UL 10B, UL 10C, and UBC 7-2 (1997) compliance, which matters if the opening is part of a fire-rated door assembly.
6) For a fire-rated opening in a hospital corridor, which threshold should I specify?
The Cal-Royal CR3726 is the one of these carrying fire-door credentials: 3-Hr Positive Pressure rated with UL 10B, UL 10C, and UBC 7-2 (1997) compliance, in a 1/4 inch by 6 inch saddle profile that is Handicap Accessible and Barrier Free over carpet. The Pemko 272 Series is stated as ADA compliant heavy-duty aluminum at the same 1/4 inch by 6 inch size, and the NGP 1013 is stated as BHMA certified at 1/4 inch by 10 inches - both are dimensional matches for the accessibility side, but the fire-assembly ratings are what the CR3726 brings to the submittal.
7) What finishes does the CR3726 threshold come in, and which one matches dark bronze frames?
Two: Aluminum (mill) and Dark Bronze, the latter ordered as DURO. Pick the dark bronze to line up with bronze anodized aluminum entrances and dark frames; mill aluminum is the usual match for clear anodized storefront.
8) Is the Cal-Royal CR3726 heavy enough for a high-traffic commercial entrance?
It is built for commercial duty, not residential. Cal-Royal lists the CR 3700 Series as heavy-duty for high-traffic commercial use, and the CR3726 is specified for office buildings, schools, healthcare, retail, industrial and warehouse, multi-tenant residential and government facilities.
9) Can I cut the CR3726 threshold down to fit my opening?
Aluminum saddle thresholds are routinely field cut to the opening width, which is why the 48, 72 and 96 inch lengths are useful for non-standard frames. Order the next length up from your measured opening. Cut ends on an anodized threshold leave bare aluminum, so keep the cut at the frame rabbet where it will be concealed.
