The Cal-Royal DIB1 Adjustable Drive-In Ball Catch with Full Lip Strike is a compact door hardware solution generally used on closet doors where a latch is not used or needed. Constructed from durable diecast material, this drive-in ball catch pairs with a jamb-mounted lip strike to hold doors securely closed without the need for traditional latching hardware.

Cal-Royal DIB1-26D – Frequently Asked Questions

1) Will a Cal-Royal DIB1 ball catch hold a closet door shut without a latch or lockset?
That's exactly what the DIB1 is for. It's a drive-in ball catch that mounts into the door edge and engages a jamb-mounted full lip strike, holding the door closed on doors where no latch is used or needed, like closet and utility doors. There's no bolt to throw and no key or lever involved: you pull the door and the spring-loaded ball releases. If you need the door to actually lock or to hold under force, this is not the part.
2) What size hole do I drill in the door edge for the Cal-Royal DIB1 drive-in ball catch?
The catch has a 1/2 inch bolt diameter, so the door edge bore is sized to that, and the body measures 3/4 x 6 x 1-1/4 inches. Drill for the 1/2 inch diameter and drive the catch in; the mating strike is 15/16 x 1-15/16 inches and mortises into the jamb. Confirm the door edge is thick enough to take a 1/2 inch bore without breaking out the faces.
3) Is a ball catch the right choice, or do I need a flush bolt on my pair of doors?
Different jobs. A ball catch like the DIB1 just holds a door closed by friction against a lip strike; it does nothing to secure an inactive leaf. If you have a pair of doors and need the inactive leaf held top and bottom so the active leaf can latch against it, you want a flush bolt instead, such as the Trimco 3999 6 inch corner mount or the Orca Hardware 6 inch flush bolt with radius corners. For a fire rated pair, an automatic flush bolt set like the Ives FB41 is the type to look at.
4) Does the Cal-Royal DIB1 ball catch meet a BHMA standard for commercial work?
It conforms to ANSI/BHMA A156.9 B23013, which is the auxiliary hardware standard, and it's classed as commercial hardware. That's the citation to put on a submittal when a spec calls for a catch on closet or utility doors in an office, school, healthcare, or municipal building.
5) Is the Cal-Royal DIB1 ball catch fire rated for a labeled door opening?
Use a fire rated flush bolt on a labeled opening, not a ball catch. Among the fire rated options we carry, the Ives FB41 automatic flush bolt set for wood doors is listed at 90 minutes, the Ives FB42 top automatic flush bolt for wood doors comes with an auxiliary fire latch, and ABH's 1860P/1862P automatic flush bolt pair is fire rated 3-hour with a thermal lock. Match the bolt to the door construction, wood or metal, when you order.
6) What is the difference between a Cal-Royal DIB1 ball catch and a manual flush bolt like the Ives FB358?
They solve different problems even though both hold a door closed. The Cal-Royal DIB1 is a drive-in ball catch with a full lip strike, used on closet doors and similar openings where a latch is not used or needed - the spring-loaded ball simply holds the door shut and releases when it is pulled. The Ives FB358 is a manual flush bolt with a 3/4 inch throw and a 1/2 inch bolt diameter, mortised into the edge of an inactive leaf and thrown by hand to pin that leaf to the head or the floor so the active leaf has something to latch into. If you have a pair of doors and need the inactive leaf held rigid, the FB358 is the part; if you have a single closet door with no latch, the DIB1 is.
7) Can a ball catch be used on a fire rated pair of doors instead of a flush bolt?
No. A fire rated pair needs a bolt that positively pins the inactive leaf, and that is what parts like the Ives FB41 automatic flush bolt set for wood doors carry a 90 minute fire rating for, or the ABH 1854 Series manual flush bolt set with fire bolt for metal doors. The Cal-Royal DIB1 is a ball catch that holds a door by spring pressure against a lip strike; it conforms to ANSI/BHMA A156.9 B23013 as a catch and is intended for closet doors and similar openings where a latch is not used or needed. On a labeled opening, specify the fire rated flush bolt that matches the door material - FB41 for wood, the ABH 1854 for metal.
8) I need something for the top of an inactive wood door that latches itself when the door closes - what do I use instead of a drive-in ball catch?
Use an automatic flush bolt. The Ives FB42 is a top automatic flush bolt for wood doors with an auxiliary fire latch, and the Ives FB41 is an automatic flush bolt set for wood doors with a 3/4 inch throw carrying a 90 minute fire rating. Automatic bolts throw when the active leaf closes against them, so no one has to reach up and set them. The Cal-Royal DIB1 has no bolt of that kind - it is a drive-in ball catch whose 1/2 inch bolt is a spring-loaded ball that engages the mating strike to hold the door, not to lock the leaf to the frame head.
9) For a 3-hour rated pair that needs the inactive leaf to bolt automatically, what is the alternative to a catch?
The ABH 1860P/1862P is an automatic flush bolt pair, fire rated 3 hours, with a thermal lock. That is the part for a labeled pair where the inactive leaf must secure itself as the doors close. A Cal-Royal DIB1 is a commercial-duty drive-in ball catch conforming to ANSI/BHMA A156.9 B23013, built for closet and similar doors where a latch is not used or needed, and it does not bolt a leaf to the frame at all.
10) Can the Cal-Royal DIB1 ball catch be adjusted if the door rattles or is too hard to open?
Yes. The DIB1 is an adjustable drive-in catch, so the ball tension can be set after installation: back it off if the door is hard to pull open, tighten it if the door rattles or drifts. That adjustment is usually easier than re-cutting the jamb strike, so set the strike alignment first, then dial in the tension.
11) What finishes does the Cal-Royal DIB1 ball catch come in to match the rest of my door hardware?
Seven architectural finishes: US1 flat black, US5 antique brass, US10B antique bronze oiled, US15 satin nickel, US15A satin nickel oxidized, US26 polished chrome, and US26D satin chrome. For a building already standardized on satin chrome levers, US26D is the match; US15 satin nickel is the common residential-look pairing in multi-family.
12) Do I have to buy the strike separately for the Cal-Royal DIB1 drive-in ball catch?
The full lip strike is included, measuring 15/16 x 1-15/16 inches. Nothing else is required to complete a standard closet door install beyond the fasteners for the strike and a bore in the door edge for the 1/2 inch catch body.
13) Does the Cal-Royal DIB1 need to be handed left or right?
No handing. A ball catch engages a lip strike straight on, so the same DIB1 works on a left hand or right hand door and swings either way. The only orientation decision is which jamb face the lip strike lands on.
14) What holds an inactive metal door leaf if a drive-in catch will not work?
For hollow metal, the ABH 1855S is a manual flush bolt single for metal doors with a 3/4 inch throw, and the Ives FB457 is a manual flush bolt with a 12 inch rod length for metal doors and carries a fire rating. For a bottom bolt, the ABH 1858 is a universal bottom fire bolt in the 1858 Series with manual operation. The Cal-Royal DIB1 mounts by driving into the door edge and works against a jamb-mounted lip strike measuring 15/16 inch by 1-15/16 inch, which suits a single closet door rather than an inactive leaf on a pair.
15) Is a 6 inch flush bolt like the Trimco 3999SE a substitute for a Cal-Royal DIB1?
The 6 inch dimension is a coincidence, not a match. The Trimco 3999SE is a 6 inch corner mount square end flushbolt, and the 3999 is the same length in a rounded end - both mount at the corner of the door face and throw a rod into the frame or floor. The Cal-Royal DIB1 body measures 3/4 inch by 6 inch by 1-1/4 inch, but it drives into the door edge and holds against a lip strike rather than bolting the leaf. If the drawing calls for a corner mount flushbolt on a pair, the 3999 or 3999SE is the part; if it calls for a closet door catch, it is the DIB1.
16) What do I specify if the inactive leaf has to be released with a key rather than by hand?
Adams Rite builds cylinder-operated flushbolts for that. The 1870 Series is a cylinder-operated flushbolt with key control, and the 1877 is a cylinder-operated flushbolt for paired wood doors. For two-point control, the MS1880/MS1881 are two-point flushbolts with an interlock mechanism and the MS2180 Series is an auto-release two-point flushbolt with a Smartlock mechanism. None of that applies to the Cal-Royal DIB1, which is an adjustable drive-in ball catch with a full lip strike and has no cylinder or keyed function - it holds the door by spring pressure only.
17) The existing hardware is mortised into the door edge with a faceplate - will a Cal-Royal DIB1 drop into that prep?
Probably not without patching. Mortise-prep parts such as the Delaney 7 inch slide type mortise-in flush bolt, the Delaney 7 inch mortise extension flush bolt, and the Delaney 6 inch square end solid brass flush bolt sit in a routed pocket with a faceplate screwed to the door edge. The Cal-Royal DIB1 uses a drive-in installation that mounts into a bored hole in the door edge for a low-profile finish, with a 1/2 inch bolt diameter and a body of 3/4 inch by 6 inch by 1-1/4 inch. Replacing a mortised bolt with the DIB1 means filling the old faceplate pocket; going the other way, a Delaney mortise bolt covers a wider prep.
18) Both the Cal-Royal DIB1 and the Ives FB358 list a 1/2 inch bolt - are they interchangeable?
No. The Ives FB358 is a manual flush bolt whose 1/2 inch bolt diameter throws 3/4 inch into a strike in the head or floor, and it carries a fire rating. The Cal-Royal DIB1 also lists a 1/2 inch bolt diameter, but that is the spring-loaded ball that presses into the included full lip strike measuring 15/16 inch by 1-15/16 inch to hold a closet door closed. Same number, different job and different strike prep - order by the function you need, not by the bolt dimension.
19) I need a flush bolt with a shorter throw and an offset for a rabbeted or narrow stile condition - what covers that?
The International Door Closers FB-1202 is built for that condition: a flush bolt with a positive U joint actuator, a 5/8 inch throw, a 1/8 inch offset with a 7/8 inch backset, square end, supplied with a guide. The Orca Hardware 86SQ Series is a 6 inch flush bolt with radius corners if the existing faceplate cutout is rounded. The Cal-Royal DIB1 has no backset or offset dimension of that kind because it is a drive-in ball catch rather than a rod-and-guide bolt.
20) Is the Cal-Royal DIB1 ball catch durable enough for daily use across a portfolio of units?
The body is diecast and the product is classed as commercial hardware, so it's built for repeated daily use on closet and other light-duty doors. For a property manager standardizing across units, ordering one finish across the portfolio keeps replacements interchangeable, since the catch, the 1/2 inch bolt, and the lip strike are the same part in every finish.
21) What is the Cal-Royal model number for this ball catch when I place an order?
Cal-Royal DIB1 is the ordering designation, and the product model is MB85R. Specify the finish code with it, for example DIB1 US26D for satin chrome.
