Cal-Royal CRB800-US26D – Frequently Asked Questions

1) Will the Cal-Royal CRB800 deadbolt fit a 1-3/4 inch commercial door?
Yes. The CRB800 is adjustable across a door thickness range topping out at 2 inches (51mm), so standard 1-3/4 inch commercial doors are covered, as are thicker 2 inch doors that many Grade 1 deadbolts won't reach. For comparison, most competing single cylinder deadbolts stop at 1-3/4 inches.
2) What bore sizes do I need to prep the door for a Cal-Royal CRB800 deadbolt?
Standard tubular deadbolt prep: a 2-1/8 inch cross bore through the face of the door for the lock housing, and a 1 inch edge bore for the bolt. If the door already has a 2-1/8 inch bore from an old deadbolt, the CRB800 drops into it with no new boring.
3) Do I have to specify the backset when ordering the Cal-Royal CRB800?
Yes, backset is a required selection: 2-3/8 inch or 2-3/4 inch. The 2-3/4 inch latch is what ships as standard and it's the UL Listed 3 hour fire rated bolt; 2-3/8 inch is the optional backset and must be called out on the order. Faceplates differ too, 2-1/4 x 1-1/8 inches with the 2-3/4 inch backset and 2-1/4 x 1 inch for the 2-3/8 inch version.
4) Is the Cal-Royal CRB800 deadbolt fire rated for a labeled opening?
The latch bolt is UL Listed 3 Hour Fire Rated, supplied with the standard 2-3/4 inch backset, and the deadbolt itself is Grade 1 heavy duty. That's the combination institutional and MRO buyers need on labeled stair, corridor, and tenant doors.
5) Can I key the Cal-Royal CRB800 into my existing building master key system?
In most cases yes. It ships with a 6-pin solid brass "C" keyway, and the cylinder is also available to match Schlage E and C-K, Russwin D1-2-3-4, Corbin 59/60, Corbin-Russwin L4, Sargent LA-LB-LC, Falcon/Weiser E, Arrow A, Yale 8, Yale GA, and Kwikset. High security cylinders from Medeco, Assa, Kaba, and Cal-Royal HSK are accepted as well, so an existing restricted-key program can carry over.
6) The opening needs a key on both sides instead of a thumbturn - what replaces the Cal-Royal CRB800?
The CRB800 is a cylinder x thumbturn deadbolt, so a keyed-both-sides opening needs a double cylinder unit. Double cylinder options include the Design Hardware D1 Series, Grade 1 extra heavy duty for 1-3/4 inch doors; the Dexter DB1000 double cylinder, Grade 1 for 1-3/8 to 1-7/8 inch doors; the Delaney LU Series, Grade 2; the Hager 3214; and the Deltana 7312KA2, Grade 3 for 1-3/8 to 2 inch doors.
7) What should I use instead of the Cal-Royal CRB800 on an exit door where no key is wanted outside?
The CRB800 is keyed outside with an inside thumbturn. For an exit-only opening, the Arrow E60 is a Grade 2 non-keyed exit deadlock with blank plate x thumbturn function for 1-3/8 to 1-3/4 inch doors. If the outside must be keyed but the inside plain, the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock with cylinder x blank function for 1-3/4 to 2-1/4 inch doors, and the DL3211 covers 1-3/4 inch doors.
8) I need an SFIC-prepped deadbolt shipped less core - how does that compare to the Cal-Royal CRB800?
The CRB800 is offered in a standard core version and an interchangeable core version, the IC option accepting compatible 6 or 7 pin cores from BEST, Falcon, and Arrow. Peers set up the same way include the Arrow E61 26D IC, an SFIC prep less core deadlock for 1-3/8 to 1-3/4 inch doors; the Deltana CL200LAIC, a Grade 2 interchangeable core single deadbolt with 2-3/4 inch backset; and the Delaney LM Series Grade 1 single cylinder less core deadbolt in dull chrome US26D.
9) Which deadbolts look like substitutes for the Cal-Royal CRB800 but will not fit the same bored prep?
The CRB800 is a bored deadbolt needing a 2-1/8 inch cross bore and 1 inch edge bore. Mortise and surface units are not drop-ins for that prep: the Dormakaba D900 is a small case mortise deadbolt, the Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch, the Codelocks CL200 is a surface deadbolt with key override, and the DynaLock 1300 Series is a mortise electric deadbolt. The Arrow 460 is a mortise lock strike rather than a lock, and the Baldwin 8BR0618001 is a deadbolt spacer.
10) What are my options if I need a fire rated deadbolt and want to compare the Cal-Royal CRB800 to another brand?
The Cal-Royal CRB800 carries a UL Listed 3 Hour Fire Rated 2-3/4 inch latch bolt and is Grade 1 rated. Hager offers fire rated deadbolts as well: the 3118 is Grade 1 with a Schlage C keyway and 6-pin cylinder for 1-3/8 to 1-3/4 inch doors, and the 3115 and 3215 are Grade 2 for the same thickness range. The CRB800 accepts a 6-pin C keyway as standard and also lists compatibility with Schlage C-K cylinders.
11) What comes in the box with a Cal-Royal CRB800 deadbolt?
Each deadbolt includes the standard "C" 6-pin cylinder, the UL Listed 2-3/4 inch backset latch with a 1-1/8 x 2-1/4 inch faceplate, and the 1-1/8 x 2-3/4 inch strike with 3 inch screws and the wood frame reinforcer. Inside is a thumbturn, so no second cylinder is needed. What it does not include is a latchset or lever, the CRB800 is a deadbolt only.
12) Should I use a single cylinder deadbolt or a double cylinder on a commercial exit door?
The CRB800 is key outside, thumbturn inside, which is what egress codes generally require on an occupied door because no key is needed to get out. Double cylinder (key both sides) is for glass-adjacent doors where you don't want the inside turn reachable, and it is normally restricted to doors that are not required exits. If you need key-both-sides, the Design Hardware D1 Series and Delaney LU Series are double cylinder deadbolts; if you need keyless inside only, Arrow's E60 is a non-keyed blank plate by thumbturn deadlock.
13) Is there a lighter-duty single cylinder deadbolt than the Cal-Royal CRB800 for lower-traffic doors?
Yes. The Cal-Royal CRB800 is Grade 1 heavy duty. Grade 2 cylinder x thumbturn options include the Arrow DBX61, the Dexter DB2000 single cylinder for 1-3/8 to 1-3/4 inch doors, the Falcon D211 in the D200 Series rated medium duty, the Deltana CL200LA with a 2-3/4 inch backset, the Hager 3215 with a 1 inch throw, and the Bravura 310B Elite. Grade 3 options include the Callan 200S with square trim.
14) Is there a keypad or credential-operated alternative to the Cal-Royal CRB800?
The CRB800 is key operated with a 6-pin solid brass C keyway. Electronic alternatives include the Delaney KP400, a Grade 2 electronic deadbolt with programmable remote; the Codelocks CL2200 electronic surface deadbolt in brushed steel, rated medium duty; the Codelocks CL2210 electronic mortise deadbolt; the Dormakaba Saffire LX-D RFID electronic deadbolt with BLE and electronic lock override; and the Dormakaba Nova-D RFID multihousing smart deadbolt.
15) What finishes does the Cal-Royal CRB800 deadbolt come in, and can I match it across a whole building?
Seven finishes are offered on both the standard core and IC versions: oil rubbed bronze, satin nickel, polished chrome, satin chrome, bright brass, satin brass, and antique brass. Trim is wrought brass or stainless steel, so a property manager can standardize one finish across entry, tenant, and back-of-house doors and still mix standard-core and interchangeable-core units on the same program.
16) I want decorative deadbolt trim rather than the commercial look of the Cal-Royal CRB800 - what else is there?
The CRB800 is a commercial deadbolt offered in wrought brass or stainless steel trim across finishes such as oil rubbed bronze, satin nickel, polished chrome, satin chrome, bright brass, satin brass and antique brass. For decorative trim, the Emtek #11 Tuscany is a lost wax cast bronze cylinder x thumbturn deadbolt and the Emtek 8323 Modern Disc is a brass double cylinder deadbolt. The Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt, and Bravura offers the 310RC Elite contemporary round and 310SC Elite contemporary square Grade 2 deadbolts.
