Cal-Royal BK14-10B – Frequently Asked Questions

1) Will the Cal-Royal BK14 bi-fold knob fit a 1-3/4 inch thick door?
Yes. The BK14 ships with one breakaway screw that snaps off to suit thicknesses from 1-5/8 inch up to 2 inch, plus a separate 1-3/4 inch screw, so a standard 1-3/4 inch panel is covered straight out of the pack without buying a different fastener.
2) Is the BK14 a lock, or just a pull knob for the bi-fold panel?
It is hardware only, no latch and no cylinder. The BK14 is a die cast ball knob that mounts through the bi-fold panel with a screw so you have something to grip when you fold the door open. If you need an actual locking cylindrical set for a swing door, look at a Grade 1 lockset like the Falcon K501 entrance function instead.
3) Can a TownSteel CRX-A-41 single dummy be used in place of a Cal-Royal BK14 bi-fold ball knob?
They are not interchangeable even though neither one latches. The Cal-Royal BK14 is a die cast ball knob 1-1/4 inch wide by 1-3/8 inch high that mounts to a bi-fold panel with a breakaway screw sized for 1-5/8 inch to 2 inch thicknesses. The TownSteel CRX-A-41 is a stainless steel Grade 1 ligature resistant arch trim single dummy cylindrical lockset listed for a 1-3/4 inch door, so it needs a standard bored cross bore and a full door leaf, not a folding panel face. Use the CRX-A-41 where a behavioral health or detention-type opening calls for ligature resistant trim, and the BK14 where you simply need a grip on a bi-fold closet or cabinet panel.
4) The opening needs a knob that actually latches and locks, not a bi-fold pull. What should I order instead of the Cal-Royal BK14?
The Cal-Royal BK14 is a bi-fold ball knob with a communicating function and no latch mechanism, so it cannot secure a swinging door. For a keyed opening, the Falcon K501 is a Grade 1 heavy duty entrance cylindrical lock with a push-turnbutton function, fire rated, and prepped for doors 1-3/8 inch to 2-1/4 inch thick. That covers offices, storage rooms, and tenant doors where the BK14 was only ever going to be a grip on a folding panel.
5) Will the Cal-Royal BK14 work on a fire-rated door assembly?
The BK14 is a bi-fold ball knob with a communicating function and no latching hardware, so it is not the part that carries a rated opening. Where the drawing calls for a fire rated bored lock, the Falcon K501 is listed as fire rated in a Grade 1 heavy duty entrance function for doors 1-3/8 inch to 2-1/4 inch thick. Order the K501 for the rated leaf and use the BK14 on non-rated bi-fold cabinet and closet panels.
6) How big is the Cal-Royal BK14 ball knob?
It measures 1-1/4 inch in width and 1-3/8 inch in height. That is a small pull-style ball, sized so it clears the adjacent leaf when a bi-fold folds back rather than a full lockset knob you would grip with a whole hand.
7) What finishes does the Cal-Royal BK14 bi-fold knob come in?
Five: US10B oil-rubbed bronze, US15 satin nickel, US19 matte black, US26 bright chrome, and US26D satin chrome. That range lets you match the closet knobs to the lever or knob finish already on the corridor and unit doors, which is usually the reason a property manager is buying them by the case.
8) Do I need to order a left or right hand version of the Cal-Royal BK14?
No handing to specify. The ball knob is symmetrical and mounts through a single screw hole, so the same part works on either leaf of a bi-fold pair and on either side of the opening. Pick the finish and you are done.
9) Can I use the BK14 on cabinet doors as well as bi-fold closet doors?
Yes. Cal-Royal rates the BK14 for bi-fold cabinet and closet door applications, and the screw kit spans 1-5/8 inch to 2 inch thickness, which covers most cabinet stiles and bi-fold panels. Thinner cabinet fronts below that range are outside what the supplied hardware reaches.
10) Does anything come in the box with the Cal-Royal BK14, or do I need separate screws?
Mounting hardware is included. Each knob comes with one breakaway screw that is snapped to length for thicknesses between 1-5/8 inch and 2 inch, plus one additional 1-3/4 inch screw. Nothing else is needed to hang it on a bi-fold panel.
11) We are standardizing closet and office hardware in one building. Which lock pairs with the Cal-Royal BK14 on the swinging doors?
The Cal-Royal BK14 handles the bi-fold closet panels only, in a commercial-grade die cast body offered in oil-rubbed bronze US10B, satin nickel US15, matte black US19, bright chrome US26, and satin chrome US26D. For the swinging office doors in the same corridor, the TownSteel CDC-109 is a Grade 1 heavy duty clutched cylindrical lockset in entry/office function, and the TownSteel CE/CEI-109 is the same entry/office function in a non-clutched extra heavy duty build. Clutched trim spins free when locked and the lever is forced; non-clutched does not, which is the choice to make before you place the order.
12) Is there an access-controlled version of the Cal-Royal BK14?
No, and the two products solve different problems. The BK14 is a mechanical die cast bi-fold ball knob with no cylinder and no electrical provision. If the opening needs credential or remote release, the BEST 9KW Series is a heavy duty electromechanical cylindrical lock with remote control operation, which goes into a standard bored door prep rather than a folding panel. Specify the 9KW for the controlled opening and keep the BK14 for the closet fronts.
13) Is the BK14 knob tough enough for closets in an apartment building or a school?
It is a solid die cast knob catalogued for commercial use, and Cal-Royal lists it for offices, schools, healthcare, retail, multi-tenant residential and government buildings. Die cast holds up better to daily yanking on a closet panel than a hollow stamped or plastic knob, and the finish range means you can standardize one part number across a whole property.
14) What is the difference between the TownSteel CEC-109 and the CDC-109 if I am replacing knobs across a facility that also uses the Cal-Royal BK14?
Both TownSteel models are Grade 1 entry/office function cylindrical locksets with clutched trim; the CEC/CECI-109 is built to an extra heavy duty level while the CDC-109 is a heavy duty clutched lockset. Neither one relates to the Cal-Royal BK14, which is a die cast bi-fold ball knob for cabinet and closet panels and carries no cylinder. A facility standard usually pairs one of the TownSteel cylindrical locks on the swinging doors with the BK14 on the folding panels, matched by finish.
