Cal-Royal LSD01-32D – Frequently Asked Questions

1) My existing deadbolt bore is a 2-3/8 inch backset. Do I have to order the Cal-Royal LSD a specific way?
No, backset is adjustable in the field. The LSD ships with a latch that sets to either 2-3/8 or 2-3/4 inches with a round corner faceplate, which are the two standard bored backsets, so one part number covers whichever prep is already in the door. Nothing to specify on the order.
2) I'm replacing a deadbolt that has a square corner faceplate cut into the door. Will the Cal-Royal LSD drop in?
The LSD latch has a round corner faceplate measuring 2-1/4 x 1 inch, so a square corner mortise in the door edge will leave a small gap at the corners unless you square the ends or trim to suit. The kit does include a 1/8 inch plastic filler that widens the 1 inch faceplate to suit a 1-1/8 inch wide edge prep, which covers the common wider mortise. Bore sizes are 1 inch for the latch and either 1-1/2 or 2-1/8 inches for the lock housing, so it lands on standard existing bores. The strike supplied is 1-1/8 x 2-3/4 inches with square corners.
3) Can the Cal-Royal LSD deadbolt be keyed alike with the Schlage C or Kwikset keys already on my building?
Yes. The LSD comes standard with a 6 pin solid brass "C" keyway cylinder, and it is offered in a long list of other keyways including Schlage E and C-K, Kwikset, Russwin D1-2-3-4, Corbin 59/60, Corbin-Russwin L4, Sargent LA-LB-LC, Falcon/Weiser E, Arrow A, Yale 8 and Yale GA. It's re-keyable and takes master keying and construction keying, so a property manager can fold it into an existing system rather than hand out a separate key.
4) Is a Grade 3 deadbolt good enough for a commercial building, or should I step up to Grade 2 or Grade 1?
Grade 3 under ANSI A156.2 Series 4000 is the standard duty tier. The Cal-Royal LSD is built to it and is catalogued for commercial use, which suits interior and moderate traffic openings, tenant unit entries, storage and back-of-house doors. For a main entrance, a school corridor or anything taking heavy daily cycles, step up: the Arrow DBX61 and the Dexter DB2000 single cylinder are Grade 2 cylinder x thumbturn deadbolts, and the Delaney LM Series and Dexter DB1000 single cylinder are Grade 1. The Dexter DB1000 also widens the door range to 1-3/8 through 1-7/8 inches.
5) Does this Cal-Royal deadbolt need a key on both sides, and is a thumbturn allowed on an exit door?
Single cylinder: key outside, thumbturn inside. The LSD's thumbturn is ADA compliant and ergonomic, meaning it releases with a closed fist and no tight grasping or wrist twisting, which is what an accessible egress door needs. If your code official or insurer requires a key on the inside instead, for a glass-adjacent door for example, that is a different function entirely and you'd want a double cylinder such as the Callan 210S in Grade 3 or the Dexter DB2000 double cylinder in Grade 2.
6) I need a deadbolt for a classroom or a door where the inside has to stay locked. Is the Cal-Royal LSD the right one?
No. The LSD is a plain cylinder x thumbturn deadbolt, so anyone inside can throw or retract the bolt by hand. Classroom function, where the bolt is controlled by key only from a specified side, is a different lock: the Falcon D111 is a Grade 1 classroom deadbolt with adjustable backset, and the Falcon D211 is the Grade 2 version. If you want a thumbturn with no keyed outside at all, the Arrow E60 is a non-keyed Grade 2 exit deadlock, blank plate outside x thumbturn inside, covering 1-3/8 to 1-3/4 inch doors.
7) The opening needs a key on both sides instead of a thumbturn - what replaces the Cal-Royal LSD?
The Cal-Royal LSD is a single cylinder deadbolt, cylinder x thumbturn, so it cannot be converted to key-both-sides. For a double cylinder opening, the Dexter DB2000 double cylinder is Grade 2 with a 1-3/8 inch to 1-3/4 inch door thickness range that matches the Cal-Royal LSD door range. The Hager 3214 is a Grade 2 double cylinder deadbolt with a Schlage C keyway and the same 1-3/8 inch to 1-3/4 inch range. If the door is 1-3/4 inch and the spec calls for Grade 1, the Design Hardware D1 Series is an extra heavy duty Grade 1 double cylinder deadbolt for 1-3/4 inch doors. Callan Model 210S is a Grade 3 double cylinder deadbolt if the grade requirement stays where the Cal-Royal LSD sits. Double cylinder deadbolts are restricted on egress doors in many jurisdictions, so confirm the code for the occupancy before specifying one.
8) What deadbolt should be used if the door is thicker than 1-3/4 inches?
The Cal-Royal LSD adjusts across a 1-3/8 inch to 1-3/4 inch door thickness range, so a thicker leaf needs a different lock. The Dexter DB1000 single cylinder is a Grade 1 cylinder x thumbturn deadbolt covering 1-3/8 inch to 1-7/8 inch doors. The Deltana 7312KA2 is a Grade 3 double cylinder deadbolt rated for 1-3/8 inch to 2 inch doors. For heavier commercial leaves, the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock covering 1-3/4 inch to 2-1/4 inch, though it is a cylinder x blank function with no thumbturn on the inside.
9) Which deadbolts look like substitutes for the Cal-Royal LSD but will not drop into the same opening?
Several deadbolts carry similar names but prep or function differently from the Cal-Royal LSD, a bored cylinder x thumbturn deadbolt for 1-3/8 inch to 1-3/4 inch doors with a 2-3/8 or 2-3/4 inch adjustable backset. The Emtek 2050 and 2051 European mortise deadbolts with integrated roller latch are cylinder x thumbturn but require a mortise pocket, not a bore. The Dormakaba D900 small case mortise deadbolt is likewise mortise prep. The Codelocks CL200 is a surface mounted deadbolt with key override rather than a through-bored lock. The Arrow 460 is a mortise lock strike, a frame component, not a lock. The Baldwin Reserve 8BR0618001 is a deadbolt spacer, an accessory. The Arrow E60 is a Grade 2 exit deadlock with a blank plate outside and a thumbturn inside, so it is non-keyed and cannot be keyed to a master system the way the re-keyable Cal-Royal LSD can.
10) Which deadbolt takes a small format interchangeable core instead of a conventional cylinder?
The Cal-Royal LSD ships with a solid brass 6 pin C keyway cylinder and is re-keyable for master and construction keying, but it is a conventional cylinder lock. If the facility is standardized on small format interchangeable cores, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock supplied with SFIC prep less core, for 1-3/8 inch to 1-3/4 inch doors, the same door range the Cal-Royal LSD covers. The Deltana CL200LAIC is a Grade 2 single cylinder interchangeable core deadbolt on a 2-3/4 inch backset. The Delaney LM Series is a Grade 1 single cylinder less core deadbolt in cylinder x thumbturn function.
11) What replaces the Cal-Royal LSD when the deadbolt has to be fire rated?
For an opening where the deadbolt itself must carry a fire rating, the Hager 3215 is a Grade 2 single cylinder commercial deadbolt with a 1 inch throw and a fire rating, covering 1-3/8 inch to 1-3/4 inch doors, which is the same door thickness range and the same 1 inch throw the Cal-Royal LSD provides. The Hager 3115 is the Grade 2 cylinder x thumbturn version and the Hager 3214 the double cylinder version, both fire rated over the same door range.
12) Can I put a high security cylinder like Medeco or Assa in this Cal-Royal deadbolt?
Yes. The LSD accepts Medeco, Assa and Kaba high security cylinders, as well as Cal-Royal's own HSK high security cylinders, in place of the standard 6 pin brass "C" keyway cylinder. That's the usual route when a tenant space or a records room needs patented key control on a door where the rest of the hardware stays standard.
13) Is a 1 inch throw deadbolt enough to reach the strike on a door with a wide gap?
The LSD bolt throws a full 1 inch, which is the throw length written into ANSI A156.2 for a deadbolt and the reason it holds into the frame rather than just the stop. The bolt also carries an anti-saw pin, so a blade run into the gap between door and frame spins on the pin instead of cutting through. Paired with the supplied 1-1/8 x 2-3/4 inch strike, it engages the jamb properly on a normally hung door.
14) Will someone be able to wrench the cylinder off this deadbolt from outside?
The outside cylinder on the LSD sits behind a tapered cylinder guard with a metal insert that spins free under any twisting or removal attempt, so a pipe wrench or plier attack turns the ring rather than backing the cylinder out. The bolt itself carries an anti-saw pin and throws 1 inch into the frame. That's the standard duty security package under ANSI A156.2 Series 4000, not a high security rating.
15) Does the Cal-Royal LSD deadbolt come with a strike, or do I need to order one separately?
A strike is in the box: 1-1/8 x 2-3/4 inches with square corners. The kit also includes the 1/8 inch plastic filler that adapts the 1 inch faceplate to a 1-1/8 inch wide door prep. What you supply is the door and frame prep itself, 1 inch bore for the latch and 1-1/2 or 2-1/8 inch for the housing, plus any non-standard keyway or high security cylinder you want in place of the standard 6 pin "C" keyway.
16) Does the Cal-Royal LSD deadbolt have a handing I need to specify?
None. It's a bored deadbolt with a symmetrical bolt, so there is no left or right hand to call out on the order. The only choices are finish, backset (set in the field at 2-3/8 or 2-3/4 inches) and keyway. That makes it straightforward to stock a few on the shelf for a mixed set of openings.
17) Can I use the Cal-Royal LSD on a fire rated door?
A deadbolt alone isn't the answer on a rated opening, and the LSD's stated compliance is ANSI A156.2 Series 4000 Grade 3 plus an ADA compliant thumbturn. If your opening needs a deadbolt carried on a fire rated listing, the Hager 3115 (Grade 2, Schlage C keyway) and Hager 3215 (Grade 2, 1 inch throw) both carry a fire rating and cover the same 1-3/8 to 1-3/4 inch door range.
18) Which deadbolt has a 2-3/4 inch backset only, and which adjusts like the Cal-Royal LSD?
The Cal-Royal LSD backset is field adjustable to 2-3/8 or 2-3/4 inch with a round corner faceplate, so one part covers both common bore centerlines. Among alternatives, the Deltana CL200LA is a Grade 2 single cylinder deadbolt fixed at a 2-3/4 inch backset and the Accentra D111 is fixed at 2-3/8 inch, so each has to be matched to the existing prep. The Brinks Raleigh Series round and Mendocino Series square single cylinder deadbolts are both cylinder x thumbturn with a 4 way adjustable backset, and the Falcon D111 is a Grade 1 heavy duty cylinder x thumbturn deadbolt with an adjustable backset.
19) Which deadbolts are a Grade 2 middle ground between the Cal-Royal LSD and a Grade 1 lock?
Several Grade 2 cylinder x thumbturn deadbolts sit between the Grade 3 Cal-Royal LSD and Grade 1 hardware. The Dexter DB2000 single cylinder is Grade 2 with a 1-3/8 inch to 1-3/4 inch door thickness range, matching the Cal-Royal LSD door range exactly. The Arrow DBX61 is a Grade 2 single cylinder deadbolt in the same cylinder x thumbturn function. The Bravura 310B Elite offers Grade 2 cylinder x thumbturn in a traditional round trim, with the 310RC Elite in contemporary round and the 310SC Elite in contemporary square if the trim shape has to match existing hardware. The Falcon D211 is a Grade 2 medium duty cylinder x thumbturn deadbolt in classroom function, which keys and operates differently from a standard single cylinder deadbolt.
20) Is there a Grade 3 deadbolt comparable to the Cal-Royal LSD in a square trim?
The Cal-Royal LSD is a Grade 3 cylinder x thumbturn deadbolt with round corner backset prep. For a square trim in the same grade and function, the Callan Model 200S is a Grade 3 single cylinder square trim deadbolt, cylinder x thumbturn. Callan also builds the 200S-G2 in Grade 2 with round trim if the round rose is the priority instead. The Bravura Rectangle deadbolt is a Grade 2 single cylinder cylinder x thumbturn option for a rectangular escutcheon look.
21) Is there a deadbolt keyed to Schlage C available instead of the Cal-Royal C keyway?
The Cal-Royal LSD comes standard with a 6 pin solid brass C keyway cylinder and lists optional keyways including Schlage E, Schlage C-K, Corbin 59/60, Sargent LA-LB-LC, Yale 8, and Kwikset. If a factory Schlage C keyway is preferred, the Hager 3115 is a Grade 2 cylinder x thumbturn deadbolt with a Schlage C keyway and a 1-3/8 inch to 1-3/4 inch door thickness range, matching the Cal-Royal LSD door range. The Hager 3118 is the Grade 1 version with a Schlage C keyway and 6-pin cylinder in classroom deadbolt function, over the same door range.
22) What is the equivalent of the Cal-Royal LSD deadbolt with keypad or electronic access instead of a key?
The Cal-Royal LSD is a keyed mechanical deadbolt, cylinder x thumbturn, re-keyable for master and construction keying. To move the same opening to electronic credentials, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote. The Codelocks CL2200 is a medium duty electronic surface deadbolt in a brushed steel finish, and the CL2210 is the mortise version. For RFID credentials on multifamily or hospitality doors, the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override, and the Dormakaba Nova-D is an RFID multihousing smart electronic deadbolt. These carry different prep and power requirements than a bored mechanical deadbolt.
23) The door is only prepped on one side - what deadbolt works where the Cal-Royal LSD does not?
The Cal-Royal LSD needs a through bore with a 1 inch latch bore and a 1-1/2 inch or 2-1/8 inch lock housing bore, with trim on both faces. Where only one face can be prepped, the Callan Model 205S is a Grade 3 one sided half-bore deadbolt in the same grade as the Cal-Royal LSD. For a secured door that needs no key outside at all, the Arrow E60 is a Grade 2 exit deadlock with a blank plate outside and thumbturn inside, for 1-3/8 inch to 1-3/4 inch doors.
24) Can a deadbolt replace the Cal-Royal LSD if the door also needs a latch for daily use?
The Cal-Royal LSD is a deadbolt only, cylinder x thumbturn, with no latching function, so a separate knob or lever is required on the door for everyday operation. To combine both in one keyed assembly, the Falcon H2101 is a Grade 2 entrance interconnected lock with a single cylinder deadbolt, so the deadbolt and latch retract together. For a bronze cast trim entry look with a matched deadbolt, the Emtek #11 Tuscany is a cylinder x thumbturn deadbolt. The International Door Closers DT-1851 is a long throw deadlatch and the DL-4511 a deadlatch lock, both latching devices rather than deadbolts.
25) What deadbolt goes on a hollow metal or narrow stile door where a bored deadbolt like the Cal-Royal LSD is not the right prep?
The Cal-Royal LSD is a bored deadbolt requiring a 1 inch latch bore and a 1-1/2 inch or 2-1/8 inch lock housing bore in a 1-3/8 inch to 1-3/4 inch door. Where the door is mortise prepped instead, the Corbin Russwin DL3211 is a Grade 1 cylindrical deadlock for 1-3/4 inch doors and the Dormakaba M1960 is a single cylinder cylinder x thumbturn deadbolt supplied with no trim. For an aluminum storefront or a hook bolt condition, the International Door Closers DH-1821 is a hook bolt deadlock with a flat faceplate. The Kaba Ilco 4500 Series is a heavy duty professional deadbolt.
26) What finishes does the Cal-Royal LSD deadbolt come in, and can I match it to existing hardware?
Four finishes: bright brass, satin chrome, satin stainless and oil rubbed bronze. Trim comes in wrought brass or stainless steel, so you can carry either a warm brass or a brushed metal look through a run of doors. For a property manager standardizing a building, that covers the four finishes most existing lever and deadbolt sets are already in.
27) What deadbolt suits a decorative or residential-style entry where the Cal-Royal LSD trim is too plain?
The Cal-Royal LSD is a commercial deadbolt offered in Oil Rubbed Bronze, Satin Chrome, Bright Brass, and Satin Stainless with wrought brass or stainless steel trim. Where a decorative entry is the goal, the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt in entrance function, and the Baldwin Reserve line offers contemporary round and contemporary square double cylinder deadbolts. The Emtek 8323 Modern Disc is a brass double cylinder deadbolt, and the Emtek #11 Tuscany is a lost wax cast bronze single cylinder deadbolt in cylinder x thumbturn function.
