Cal-Royal CR371536-AL – Frequently Asked Questions

1) Can I use a saddle threshold on a fire rated door opening?
The CR3715 carries a 3-Hr Positive Pressure rating and meets UL 10B, UL 10C and UBC 7-2 (1997), so it is built for fire rated assemblies. Confirm the rating you need matches the door and frame label, since the threshold rating does not raise the assembly's rating on its own.
2) Is a 5 inch wide saddle threshold wide enough, or do I need a 6 or 10 inch?
5 inches suits most single-door commercial openings where the threshold only needs to cover the frame throat and the floor joint. Go wider when the sill or floor transition is deeper: ZenSupply carries the Pemko 272 Series flat saddle at 1/4 inch by 6 inches, and the NGP 1013 saddle at 1/4 inch by 10 inches for wide sills. All three share the same 1/4 inch height, so the accessible profile does not change with width.
3) My floor levels are different on each side of the door. Is a flat saddle threshold the right part?
No. A flat saddle like the CR3715 sits at one height, 1/4 inch, on both sides and assumes the finished floors are close to level. Where one side is lower, use an offset threshold: ZenSupply stocks the NGP 653 offset at 1/2 inch by 5-1/2 inches, which steps down to pick up the difference.
4) What lengths does the Cal-Royal CR3715 saddle threshold come in?
Four cut lengths: 36, 48, 72 and 96 inches. A 36 inch piece covers a standard single door, 72 or 96 inch pieces cover pairs or oversized openings, and aluminum threshold stock can be cut down on site to the exact frame-to-frame dimension.
5) Do I have to buy screws separately for a Cal-Royal CR3715 threshold?
No, fasteners come with it and are matched to the finish. MIL finish thresholds ship with zinc plated screws, brass with brass screws, color anodized with screws plated to match, and stainless steel with stainless screws. You will still need anchors suited to your substrate if you are fastening into concrete.
6) Which finish should I order for the CR3715, aluminum or dark bronze?
Both are offered, ordered as ALUMINUM (mill) or DURO, the dark bronze. Mill aluminum is the usual pick with aluminum storefront and hollow metal painted frames; dark bronze matches bronze anodized entrances and dark hardware. Every length, 36 through 96 inches, is available either way.
7) Is the Cal-Royal CR3715 heavy enough for a school or hospital entrance?
It is built for that duty. Cal-Royal lists the CR3715 as a heavy duty commercial threshold and names educational facilities, healthcare institutions, government buildings, retail and warehouse openings among its applications. It is part of the CR 3700 Series, so you can carry the same profile across every opening in a facility.
