Emtek 8553 #3 Wrought Steel Single Sided Deadbolt

No. The 8553 #3 Wrought Steel deadbolt is a single sided, non-keyed unit operated by a thumbturn from the inside only, and it ships with no cylinder and no collar. Outside there is nothing to key, so it is meant for interior doors or doors where you never need to unlock from the other side. If you need key access from outside, look at a single cylinder deadbolt such as the Arrow DBX61 or Dexter DB2000 instead.

It covers 1-3/8 inch through 2 inch doors. Standard build is for 1-3/4 inch, which is the usual commercial and exterior thickness, so if your door is thicker than that you have to specify the thickness when you order. There is a door thickness field on the order for exactly that reason.

It uses standard tubular deadbolt prep: 2-1/8 inch cross bore, 1 inch edge bore, and a backset of either 2-3/8 or 2-3/4 inches. If your existing hole matches that, the 8553 goes in without new boring. Backset is a required choice at order time, so measure center of bore to door edge first.

No, this one is built for residential use, in brass with a steel-look wrought finish, and carries no ANSI grade on record. For a commercial opening you want a graded deadbolt: the Accentra D111 and Delaney LM Series are Grade 1 cylinder-x-thumbturn units, and Hager's 3115 is a Grade 2 with a Schlage C keyway and a fire rating.

The Emtek 8553 is a single sided, non-keyed tubular deadbolt operated by a thumbturn from inside only, with no cylinder or collar on the outside face. The closest functional equivalent is the Callan Model 205S, a one-sided half-bore deadbolt in Grade 3. Both give you inside-only operation, so neither can be unlocked from the exterior. The Callan is bored as a half-bore, while the Emtek 8553 uses a 2-1/8 inch cross bore and 1 inch edge bore in a 2-3/8 inch or 2-3/4 inch backset.

The Emtek 8553 is a non-keyed single sided deadbolt with no cylinder or collar, so the exterior face is left without trim. If you want a blank plate on the outside instead, the Arrow E60 is a Grade 2 exit deadlock with a blank plate x thumbturn function that fits doors 1-3/8 inch to 1-3/4 inch thick. Both are thumbturn-only from the inside; the Arrow adds the outside plate and a Grade 2 rating, while the Emtek 8553 is a brass residential unit in the Wrought Steel collection covering 1-3/8 inch to 2 inch doors.

The Emtek 8553 cannot be operated from outside - it is non-keyed and takes no cylinder. For a keyed exterior on a residential door, the Dexter DB2000-SCT is a Grade 2 single cylinder deadbolt with a cylinder x thumbturn function for doors 1-3/8 inch to 1-3/4 inch thick, and the Dexter DB1000-SCT is the Grade 1 version covering 1-3/8 inch to 1-7/8 inch. The Hager 3115 is another cylinder x thumbturn choice and is built on the Schlage C keyway, the same keyway the 8553 bore prep is specified for.

The Emtek 8553 is a residential tubular deadbolt and carries no ANSI grade. Where a project calls for a graded deadbolt, the Accentra D111 is Grade 1 cylinder x thumbturn with a 2-3/8 inch backset for doors 1-3/8 inch to 1-3/4 inch, the Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch, and the Hager 3118 is a Grade 1 classroom deadbolt with a 6-pin Schlage C cylinder. All three are keyed from the exterior, unlike the inside-only 8553.

Two backsets are offered, 2-3/8 and 2-3/4 inches, and it is a required selection. Measure from the door edge to the center of the 2-1/8 inch cross bore. Residential doors are commonly 2-3/8; 2-3/4 is the other standard and turns up more on commercial-width stiles and on doors prepped with a wider trim plate.

The unit itself ships with no cylinder and no collar and is turned by thumbturn only. The Schlage C reference is the keyway used across this Emtek deadbolt platform, which matters if you later add a keyed exterior side to the same opening and want everything on one key. Ordered as-is, there is nothing to key.

The Emtek 8553 is a one sided thumbturn deadbolt but it takes full tubular prep, 2-1/8 inch cross bore and 1 inch edge bore. If you need a one sided unit on a half bore, the Callan Model 205S is a one sided half-bore deadbolt. For surface mounting with no boring at all, Codelocks CL200 is a surface deadbolt with key override.

The Emtek 8553 is keyed on neither side - it is a thumbturn-only single sided unit. For key-both-sides openings, the Callan Model 210S is a Grade 3 double cylinder deadbolt, the Delaney LU Series 320601 is Grade 2 double cylinder in stainless steel US32D, and the Design Hardware D1 Series is a Grade 1 extra heavy duty double cylinder deadbolt for 1-3/4 inch doors. Bear in mind a double cylinder removes the inside thumbturn that the 8553 relies on.

The Emtek 8553 is built for a standard 1-3/4 inch door and covers a 1-3/8 inch to 2 inch range, with thicker doors specified at time of order. Among comparable units, the Deltana 7312KA2 double cylinder deadbolt also lists 1-3/8 inch to 2 inch, and the Corbin Russwin DL3011 Grade 1 cylindrical deadlock goes from 1-3/4 inch to 2-1/4 inch. Note that both of those are keyed products, while the 8553 is thumbturn only from the interior.

The Emtek 8553 is ordered in a fixed 2-3/8 inch or 2-3/4 inch backset, so the existing bore has to be measured first. If you would rather have one unit that covers either bore, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset for 1-3/8 inch to 1-3/4 inch doors, and the Brinks Raleigh Series E2401 is a transitional round single cylinder deadbolt with a 4-way adjustable backset. Both are keyed from the outside rather than inside-only like the 8553.

The Emtek 8553 uses a standard thumbturn on the interior as its only means of operation. For openings where grip is a concern, the Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn, fitting doors 1-3/8 inch to 1-3/4 inch thick. The trade-off is that the Cal-Royal is a keyed cylinder x thumbturn unit, so the exterior takes a cylinder, whereas the 8553 has no cylinder at all.

The specification lists brass as the material, while the Wrought Steel name refers to the #3 Wrought Steel design collection and its steel look. Finish options are Flat Black Steel and Satin Steel, both in the Rustic Living theme.
