Emtek 8552 #2 Wrought Steel Single Sided Deadbolt

No, it is a residential product, non-keyed and thumbturn only. For commercial openings look at graded hardware instead: the Accentra D111 is Grade 1 cylinder x thumbturn with a 2-3/8 inch backset, the Cal-Royal CB160 is Grade 2 single cylinder, and the Arrow E60 is a Grade 2 non-keyed exit deadlock for 1-3/8 to 1-3/4 inch doors if you specifically want a thumbturn-operated commercial unit.

It uses a standard tubular prep: 2-1/8 inch cross bore, 1 inch edge bore, with a backset of either 2-3/8 or 2-3/4 inch. That is the common residential deadbolt prep, so it typically goes straight into an existing hole. Backset is a required choice at order, so measure from the door edge to the center of the 2-1/8 inch hole before you pick.

The Emtek 8552 is a single sided, non-keyed deadbolt operated by a thumbturn from the inside only, with no cylinder or collar. Two peers cover the same idea in different ways: the Callan 205S is a Grade 3 one-sided half-bore deadbolt, meaning the outside face is not bored through, and the Arrow E60 is a Grade 2 exit deadlock with a blank plate on the outside and a thumbturn inside, for 1-3/8 inch to 1-3/4 inch doors. The Emtek accepts 1-3/8 inch to 2 inch doors.

The Emtek 8552 is non-keyed and turns from the inside only. For an outside key, 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, the Dexter DB2000-SCT is a Grade 2 cylinder x thumbturn deadbolt over the same thickness range, and the Dexter DB1000-SCT is Grade 1 cylinder x thumbturn covering 1-3/8 inch to 1-7/8 inch. The Hager 3215 uses a Schlage C keyway, the same keyway family the 8552 page specifies.

The Emtek 8552 is a residential Wrought Steel deadbolt. On graded commercial work, the Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch, the Accentra D111 is a Grade 1 cylinder x thumbturn deadbolt with a 2-3/8 inch backset for 1-3/8 inch to 1-3/4 inch doors, and the Falcon D111 is a Grade 1 heavy duty classroom deadbolt with an adjustable backset.

The 8552 ships with no cylinder and no collar, so nothing is keyed out of the box. The Schlage C keyway reference is the family standard for the tubular deadbolt platform. If you want the opening keyed to match other doors on the property, this is not the right model, pick a cylinder x thumbturn deadbolt instead.

The 8552 comes with no outside collar or trim at all, so the exterior face is bare. If you need a finished blank plate on the outside, the Callan 205S is a Grade 3 one-sided half-bore deadbolt, and the Arrow E60 is a blank plate x thumbturn deadlock. Both cover the same idea with an outside plate included.

The Emtek 8552 is rated for 1-3/8 inch to 2 inch doors, with 1-3/4 inch as the standard. Among the peers, the Deltana 7312KA2 double cylinder deadbolt covers the same 1-3/8 inch to 2 inch range, and the Corbin Russwin DL3011 Grade 1 cylindrical deadlock covers 1-3/4 inch to 2-1/4 inch. Most of the residential-style units, such as the Dexter DB2000 series, stop at 1-3/4 inch.

No. The Emtek 8552 has a thumbturn inside and no cylinder at all, so it is keyless on both faces. A double cylinder unit such as the Callan 210S Grade 3, the Delaney LU Series Grade 2 in stainless steel, or the Design Hardware D1 Series Grade 1 extra heavy duty for 1-3/4 inch doors requires a key on both sides, including from the inside. That changes egress behavior and is a different decision from the 8552, not a drop-in swap.

The Emtek 8552 is ordered with a fixed backset chosen at purchase, either 2-3/8 inch or 2-3/4 inch, against a 2-1/8 inch cross bore and 1 inch edge bore. If the bore is unknown, the Brinks Raleigh E2401 round and Mendocino E2402 square single cylinder deadbolts use a 4-way adjustable backset, the Cal-Royal ED500 Grade 3 has an adjustable backset for 1-3/8 inch to 1-3/4 inch doors, and the Falcon D111 Grade 1 also adjusts.

The Emtek 8552 uses a Wrought Steel thumbturn in the #2 design, offered in Flat Black Steel and Satin Steel. Where an easier grip is called for, the Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn for 1-3/8 inch to 1-3/4 inch doors. Note the LSD is a keyed single cylinder unit, so the outside face is bored for a cylinder, unlike the 8552.

The Emtek 8552 is a tubular deadbolt for a 2-1/8 inch cross bore and 1 inch edge bore. Several deadbolt-named peers use a different prep entirely: the Codelocks CL200 and the electronic CL2200 are surface mounted deadbolts, the Dormakaba D900 and the DynaLock 1300 are mortise cases, and the Detex DX Series is a hinge side multi-point locking deadbolt. None of those drop into a standard tubular deadbolt bore.

No. The Emtek 8552 ships with no cylinder or collar and is non-keyed, so there is nothing to core. For an SFIC program, 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, the Deltana CL200LAIC is a Grade 2 single deadbolt with interchangeable core prep and a 2-3/4 inch backset, and the Delaney LM Series is a Grade 1 single cylinder less core deadbolt in dull chrome.

Two: Flat Black Steel (8552FBS) and Satin Steel (8552SWS). Both are part of Emtek's Wrought Steel collection, which is a rustic look meant to pair with the other Wrought Steel knobs and levers in the same finish across a home.

The lock is brass internally with a steel wrought-look trim, catalogued under Emtek's Wrought Steel #2 series. Emtek positions this one for interior installation and appearance, so it suits pantry, bedroom, or closet doors where you want the rustic steel face to match the rest of the Wrought Steel line rather than an exterior entry.

The Emtek 8552 is a mechanical, non-electronic deadbolt turned by hand from inside. For code or credential access, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, 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. All three need power and enrollment, which the 8552 does not.

The Emtek 8552 carries the #2 Wrought Steel trim in a rustic style, offered in Flat Black Steel and Satin Steel. For a different face, the Bravura 310B Elite is a Grade 2 traditional round deadbolt, the 310RC Elite is contemporary round and the 310SC Elite is contemporary square, and the Bravura 910 is a Grade 2 rectangle trim. Baldwin Reserve also offers contemporary round and contemporary square double cylinder deadbolts. All of those are keyed units rather than single sided.
