Cal-Royal CALSF – Frequently Asked Questions

1) What is a strike filler plate for on a commercial door frame?
A strike filler covers a strike prep that is no longer being used. When you swap a lockset, move to a different latch height, or convert an opening, the old cutout in the frame is left open. The Cal-Royal SF drops into that cutout so the jamb reads as finished instead of showing a hole. It is a cover plate, not a latching part, so it does not secure the door on its own.
2) What size opening does the Cal-Royal SF strike filler cover?
The SF filler measures 1-1/4 x 4-7/8 inches, with 1-5/8 inches at the lip. Measure your open strike cutout in the jamb before ordering: the plate has to be at least as large as the hole in both directions, and the 1-5/8 inch lip dimension has to suit the depth of the frame's strike lip return. If your existing prep is a taller 4-7/8 inch ANSI strike cutout, this covers it; a shorter T-strike or roller latch prep will sit inside that footprint.
3) I am converting a door from a knob lock to an exit device. Do I need a filler plate for the old strike hole?
Yes, if the new hardware does not sit over the old cutout. Exit device strikes and electric strikes rarely land on the same footprint as a cylindrical lock strike, so the old prep is left exposed. The Cal-Royal SF filler, 1-1/4 x 4-7/8 inches with a 1-5/8 inch lip, closes that opening. Confirm the abandoned prep falls inside those dimensions, because a filler cannot span a cutout larger than itself.
4) Is the Codelocks CL4000-RSB strike box an alternative to the Cal-Royal SF strike filler?
No, they do different jobs. The Cal-Royal SF is a 10 Ga. steel filler that covers an unused strike preparation in a commercial door frame for a clean, finished appearance. The Codelocks CL4000-RSB is a glass door strike box suitable for use with CL4000 or CL4500 glass door locks, so it receives a latch on a glass door rather than closing off an opening in a hollow metal frame. If the frame prep is being abandoned, the SF filler is the part; if a glass door lock needs something to latch into, the CL4000-RSB is.
5) What do I use if the frame opening still needs to hold a latch instead of being filled?
The Cal-Royal SF is a blank filler, sized 1-1/4 inch by 4-7/8 inch with 1-5/8 inch at the lip, and it closes a strike prep rather than accepting a latch. Where the opening still has to catch a door, the ABH 1890 Series pairs a roller latch with a full lip cast strike and 5/16 inch adjustable projection, and the ABH 1895 Series pairs a roller latch with a T strike and 1/2 inch adjustable projection. Choose between those two on the strike style the frame prep suits and the projection adjustment you need.
6) Is a strike filler the same thing as a strike box?
No. A strike box is the dust box that sits behind a strike to receive the latch bolt, so it is part of a working latching opening. The Cal-Royal SF is a blank filler that covers a prep you are retiring. If you actually need a box behind a lock, look at a box built for that lock family, for example the Codelocks CL4000 glass door strike box for the CL4000 and CL4500 glass door locks.
7) My door does not latch tight and I have an old strike hole. Should I use a filler or a roller latch?
Those solve different problems. The Cal-Royal SF filler only closes an abandoned strike cutout, it does nothing to hold a door shut. If the door itself is not staying closed, you want a roller latch: the ABH 1890 Series comes with a full lip cast strike and 5/16 inch adjustable projection, and the ABH 1895 Series uses a T strike with 1/2 inch adjustable projection. Buy the filler only for the leftover hole once the new hardware is in.
8) Will the Cal-Royal SF filler work on a hollow metal frame or does it only suit wood?
The SF is made for door frames in commercial installations, which in practice means hollow metal and aluminum jambs prepped for a standard strike. Fit is decided by the cutout, not the frame material: if the abandoned prep in your jamb sits inside 1-1/4 x 4-7/8 inches with a 1-5/8 inch lip, the plate covers it.
9) Difference between a strike filler and the Securitron AOS armature offset strikes?
The Cal-Royal SF strike filler is a commercial door frame accessory that covers an unused strike cutout in 10 Ga. steel. The Securitron AOS is a set of armature offset strikes, which is magnetic lock hardware that positions the armature relative to the magnet. On a maglock conversion you may well need both: the AOS to set up the mag hardware, and the SF to close the mechanical strike prep the old lock left behind in the frame.
10) Can a Trimco 1268 anchor plate cover an old strike cutout?
The Trimco 1268 is an anchor plate at 3-1/2 inch diameter, a round plate, so its shape does not follow a rectangular frame strike prep. The Cal-Royal SF is cut to 1-1/4 inch by 4-7/8 inch with 1-5/8 inch at the lip specifically to match standard commercial frame strike cutouts, including the lip return. For covering a strike prep in the frame, the SF is the matched profile.
11) How many strike fillers do I order for a building standardization job?
One per abandoned strike prep, counted per leaf, not per opening. On a pair of doors where you are removing hardware from both leaves, that is two. The SF is a single model, CALSF, so there is no handing or size choice to track across a fleet of openings, which is what makes it straightforward to standardize on.
