Cal-Royal EDD400-26D – Frequently Asked Questions

1) Will the Cal-Royal EDD400 deadbolt fit a 1-3/8 inch door, or is it only for 1-3/4 inch commercial doors?
Both. The EDD400 covers doors 1-3/8 inch through 1-3/4 inch thick, so the same part works on an older interior slab and on a standard 1-3/4 inch commercial door. The backset adjusts between 2-3/8 and 2-3/4 inches, the two standard bored-lock backsets, so it drops into an existing 161 prep either way.
2) What does double cylinder mean on the EDD400, and should I use it on an exit door?
Double cylinder means a key is required on both sides of the door, with no thumbturn to throw the bolt from inside. That is the reason people specify it next to glass or a sidelite, where someone could reach through and turn a thumbturn. It also means nobody exits without a key, which many jurisdictions prohibit on a required egress door. If the opening is an exit, a cylinder x thumbturn deadbolt such as the Hager 3215 or the Dexter DB2000 single cylinder is the correct choice instead.
3) Is a Grade 3 deadbolt like the Cal-Royal EDD400 enough for a commercial building?
The EDD400 is built to ANSI A156.2 Series 4000, Grade 3, which is the light commercial and residential tier. It suits tenant entry doors, storage rooms, offices and multi-family units. For high-traffic or high-abuse openings, step up: the Design Hardware D1 Series is a Grade 1 double cylinder, and Delaney's LU Series and the Dexter DB2000 are Grade 2 double cylinder options.
4) Can I key the Cal-Royal EDD400 into my existing building master key system?
The EDD400 ships with a re-keyable Kwikset keyway and accepts master and construction keying, so a locksmith can bring it onto an existing Kwikset system. If your building runs Schlage C or Weiser, those keyways are available on special factory order. For a Schlage C system off the shelf, the Hager 3214 double cylinder deadbolt comes with the Schlage C keyway.
5) Will the EDD400 bolt reach my existing strike, and what strike comes with it?
Full 1 inch bolt throw, which is what lets it engage a frame strike through a normal gap. The standard strike is a 1 x 2-1/4 inch round corner with full lip. Square corner is available if your frame is prepped that way, and there is an optional 1-1/4 x 3-5/8 inch security strike with 3 inch screws that anchors into the stud behind the jamb.
6) What is the closest equivalent to the Cal-Royal EDD400 double cylinder deadbolt at the same Grade 3 level?
The Callan Model 210S is also a Grade 3 double cylinder deadbolt, and the Deltana 7312KA2 is a Grade 3 double cylinder deadbolt rated for doors 1-3/8 inch to 2 inch thick. The Cal-Royal EDD400 is Grade 3 double cylinder with a 2-3/8 or 2-3/4 adjustable backset and fits 1-3/8 inch to 1-3/4 inch doors, so on a 2 inch door the Deltana covers a thickness the EDD400 does not.
7) If a specification calls for a Grade 1 double cylinder deadbolt, what should be used instead of the Cal-Royal EDD400?
The Cal-Royal EDD400 is Grade 3. For a Grade 1 double cylinder deadbolt, the Design Hardware D1 Series is Grade 1 extra heavy duty double cylinder for 1-3/4 inch doors, and the Dexter DB1000 is a Grade 1 double cylinder deadbolt for 1-3/8 inch to 1-7/8 inch doors. The Dexter covers the thinner doors the Design Hardware unit does not.
8) A door needs a thumbturn on the inside instead of a second key cylinder. What replaces the Cal-Royal EDD400?
The Cal-Royal EDD400 is a double cylinder deadbolt, keyed on both sides. For cylinder outside and thumbturn inside, the Callan Model 200S is a Grade 3 cylinder x thumbturn deadbolt with square trim, and the Hager 3215 is a Grade 2 single cylinder deadbolt with a 1 inch throw for 1-3/8 inch to 1-3/4 inch doors. Egress codes in many occupancies prohibit a key-both-sides deadbolt, so confirm the function against the authority having jurisdiction.
9) What deadbolt should be used instead of the Cal-Royal EDD400 on a thicker door over 1-3/4 inches?
The Cal-Royal EDD400 fits doors 1-3/8 inch to 1-3/4 inch. For thicker stock, the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock for doors 1-3/4 inch to 2-1/4 inch, and the Deltana 7312KA2 Grade 3 deadbolt covers 1-3/8 inch to 2 inch.
10) Which products look like substitutes for the Cal-Royal EDD400 double cylinder deadbolt but are not?
Several items in the deadbolt family are not drop-in replacements for the Cal-Royal EDD400, which is a keyed double cylinder bored deadbolt. The BEST 8T is a tubular deadbolt tube component rather than a complete lock, the Baldwin Reserve 8BR0618001 is a deadbolt spacer, and the Arrow 460 is a mortise lock strike. The Arrow E60 is a Grade 2 exit deadlock that is non-keyed with a blank plate outside and thumbturn inside, so it gives no outside key control at all.
11) What alternative to the Cal-Royal EDD400 works with a small format interchangeable core keying system?
The Cal-Royal EDD400 ships with a re-keyable Kwikset keyway suitable for master and construction keying, with Weiser and Schlage C available on special factory order. If the facility keys on SFIC, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep less core for 1-3/8 inch to 1-3/4 inch doors, and the Deltana CL200LAIC is a Grade 2 interchangeable core single deadbolt with a 2-3/4 inch backset.
12) What should be specified in place of the Cal-Royal EDD400 on a fire rated opening?
The Cal-Royal EDD400 is a Grade 3 double cylinder deadbolt conforming to ANSI A156.2 Series 4000. Where a fire rating is required, the Hager 3214 is a fire rated Grade 2 double cylinder deadbolt for 1-3/8 inch to 1-3/4 inch doors, and the Hager 3118 is a fire rated Grade 1 classroom deadbolt with a Schlage C 6-pin cylinder for the same thickness range.
13) The interior side of an opening cannot be bored through. Is there an option other than the Cal-Royal EDD400?
The Cal-Royal EDD400 is a double cylinder deadbolt requiring prep on both faces. Where only one face can be prepped, the Callan Model 205S is a Grade 3 one-sided half-bore deadbolt.
14) Do I need to order the Cal-Royal EDD400 handed for a left or right hand door?
No handing to specify. The EDD400 is reversible and works on both left and right hand doors, which is why property managers can stock one part number for a whole building.
15) Can the EDD400 deadbolt go on a hollow metal door, or is it wood only?
Both. The EDD400 is rated for wood and metal doors within the 1-3/8 to 1-3/4 inch thickness range, using a standard bored prep. A drive-in bolt with adjustable backset is available as an alternative to the faceplate bolt if your prep calls for it.
16) Is there an ADA compliant deadbolt option in the Cal-Royal Chelsie ED line?
The Chelsie ED Series deadbolts use an ergonomic thumbturn that supports ADA accessibility requirements. Note that the EDD400 itself is the double cylinder version, key both sides with no thumbturn, so for an ADA operable opening you want the thumbturn version of the series rather than the double cylinder.
17) I need a double cylinder deadbolt for a door thicker than 1-3/4 inches. What are my options?
The EDD400 stops at 1-3/4 inches, so it will not work. Of the double cylinder alternatives, the Deltana 7312KA2 Grade 3 covers 1-3/8 to 2 inches and the Dexter DB1000 Grade 1 covers 1-3/8 to 1-7/8 inches.
18) What is the alternative to the Cal-Royal EDD400 if the opening needs code entry rather than a key?
The Cal-Royal EDD400 is a keyed mechanical double cylinder deadbolt. For keypad or credential entry, the Codelocks CL200 is a light duty surface deadbolt with key override, the Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel, and the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote.
19) For a decorative residential entry, what deadbolt is offered instead of the Cal-Royal EDD400?
The Cal-Royal EDD400 is a commercial Grade 3 double cylinder deadbolt in oil rubbed bronze, satin nickel, satin chrome, bright brass and antique brass. For decorative trim, the Emtek 8323 Modern Disc is a brass double cylinder deadbolt, the Baldwin Reserve double cylinder is available in contemporary round and contemporary square trim, and the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt.
20) The Cal-Royal EDD400 is a bored deadbolt. What mortise deadbolt alternatives exist for a prepped mortise pocket?
The Cal-Royal EDD400 is a bored lockset deadbolt with a 2-3/8 or 2-3/4 adjustable backset. For a mortise case, the Dormakaba D900 small case mortise deadbolt is a cylinder x thumbturn unit keyed different with Schlage keyways, the Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch in square and round trim, and the International Door Closers DH-1821 is a hook bolt deadlock with a flat faceplate.
21) Does the Cal-Royal EDD400 have a classroom function equivalent for a school door?
The Cal-Royal EDD400 is a double cylinder deadbolt keyed on both sides. For classroom function, the Falcon D111 is a Grade 1 heavy duty classroom deadbolt with adjustable backset, the Falcon D211 is the Grade 2 medium duty single cylinder version, and the Corbin Russwin DL2211 is a Grade 1 cylindrical deadlock in classroom function for 1-3/4 inch doors.
22) What finishes does the Cal-Royal EDD400 deadbolt come in?
Five: Bright Brass, Antique Brass, Satin Nickel, Satin Chrome and Oil Rubbed Bronze. Satin Chrome and Satin Nickel are the usual matches for commercial lever and closer hardware already on a building; the brass and bronze options suit residential and hospitality openings.
23) How does the hardened steel pin in the Cal-Royal EDD400 help against break-ins?
The bolt carries a hardened steel pin that resists a saw blade, so an intruder cutting the gap between door and jamb cannot cut through the bolt. Combined with the 1 inch throw and the all-metal body and cylinder with brass exterior parts, that covers the two common attacks on a deadbolt, sawing and prying.
