Emtek 8550 #2 Sandcast Bronze Single Sided Deadbolt

No. The 8550 is a single sided deadbolt operated by a thumbturn from the inside only, and it ships with no cylinder and no outside collar. The exterior face of the door gets nothing, so use it where you want the bolt thrown and retracted from inside only, such as a rarely used interior or back door. If someone needs to unlock it from the outside with a key, this is the wrong part.

Yes, it drops into a standard bore. The 8550 takes a 2-1/8 inch cross bore and a 1 inch edge bore, which is the normal residential prep, and you pick the backset to match your door: 2-3/8 inch or 2-3/4 inch. Door thickness range is 1-3/8 inch to 2 inch, with 1-3/4 inch supplied as standard unless you specify thicker.

Backset is a required selection on the 8550, offered in 2-3/8 inch and 2-3/4 inch. Measure from the door edge to the center of the existing bore: residential doors are usually 2-3/8 inch, and 2-3/4 inch is common on entry doors and where the lockset below it already uses that backset. Door thickness is a separate entry, so note anything over the standard 1-3/4 inch when you order.

It is a residential product, tubular type, with a decorative bronze single sided thumbturn and no grade rating behind it. For a commercial opening where an ANSI grade is specified, look at a Grade 1 deadbolt such as the Design Hardware D1 Series double cylinder for 1-3/4 inch doors, the Dexter DB1000 single cylinder rated for 1-3/8 to 1-7/8 inch doors, or the Accentra D111 Grade 1 with a 2-3/8 inch backset.

The 8550 will not do that job, since it is thumbturn only with no outside cylinder. For key outside and turn inside, a single cylinder deadbolt is the function you want: the Hager 3115 or 3215 in Schlage C keyway for 1-3/8 to 1-3/4 inch doors, the Arrow DBX61 Grade 2, or Deltana CL200LM Grade 1. If the exterior side should be blank but you still want a keyed prep behind it, the Arrow E60 non-keyed exit deadlock is blank plate by thumbturn.

The Emtek 8550 #2 Sandcast Bronze deadbolt is a non-keyed, single sided unit operated by thumbturn from the inside only, with no cylinder or collar, so there is no key access from the exterior. For an opening that needs outside key control, the Accentra D111 is a Grade 1 single cylinder deadbolt with cylinder x thumbturn function and a 2-3/8 inch backset, and the Dexter DB1000 single cylinder deadbolt is a Grade 1 cylinder x thumbturn unit covering 1-3/8 inch to 1-7/8 inch doors. Hager 3115 is a Grade 2 cylinder x thumbturn deadbolt that uses the Schlage C keyway, which matches the keyway the Emtek 8550 bore is prepped around.

The Emtek 8550 #2 Sandcast Bronze single sided deadbolt is a residential tubular deadbolt with thumbturn-only operation. If the same thumbturn-only, no-key-outside operation is needed on a commercial opening, the Arrow E60 is a Grade 2 exit deadlock, non-keyed, with blank plate x thumbturn function for 1-3/8 inch to 1-3/4 inch doors. The Callan 205S is a Grade 3 one-sided half-bore deadbolt, which is prepped for a partial bore rather than a full cross bore.

The Emtek 8550 #2 Sandcast Bronze deadbolt lists the Schlage C keyway. Among keyed deadbolts on the same keyway, Hager 3115 is a Grade 2 cylinder x thumbturn unit, Hager 3118 is a Grade 1 classroom deadbolt with a 6-pin cylinder, and Hager 3214 is a Grade 2 double cylinder deadbolt, all three covering 1-3/8 inch to 1-3/4 inch door thickness. Dormakaba D900 small case mortise dead bolts are also offered keyed different with SC keyways, but they are a mortise case rather than a tubular bore.

The Emtek 8550 #2 Sandcast Bronze deadbolt is built around a standard 1-3/4 inch door and accepts 1-3/8 inch to 2 inch thicknesses. For a heavier door, the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock covering 1-3/4 inch to 2-1/4 inch door thickness.

Three sandcast bronze finishes: Flat Black Bronze (FB), Medium Bronze (MB), and Tumbled White Bronze (TWB). These are living finishes on solid bronze, so they will patina and are meant to match the rest of Emtek's Sandcast Bronze collection on the same opening.

That is exactly what the 8550 is for. It mounts as a single sided deadbolt in the existing 2-1/8 inch cross bore with the thumbturn on the interior and nothing on the outside face. If your door was never bored through and you want to avoid drilling all the way, a half-bore one-sided unit like the Callan Model 205S is the other approach.

No. The Emtek 8550 #2 Sandcast Bronze is a complete tubular single sided deadbolt with thumbturn. The Arrow 460 is a mortise lock strike for latchbolt and deadbolt functions with a straight lip, so it is the frame-side strike only. The BEST 8T is a T Series tubular deadbolt tube component, meaning the bolt mechanism without the decorative trim. The International Door Closers DH-1821 is a hook bolt deadlock, a mortise-style lock case for a different door type.

The Emtek 8550 #2 Sandcast Bronze deadbolt uses a standard thumbturn on the interior face. The Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn for doors 1-3/8 inch to 1-3/4 inch thick, and it is a cylinder x thumbturn unit, so the exterior face carries a key cylinder rather than being blank.

The Emtek 8550 #2 Sandcast Bronze deadbolt is specified for residential use. For heavier service, the Design Hardware D1 Series is an extra heavy duty Grade 1 double cylinder deadbolt for 1-3/4 inch doors, the Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch, and the Falcon D111 is a heavy duty Grade 1 cylinder x thumbturn deadbolt with an adjustable backset.

The Emtek 8550 #2 Sandcast Bronze deadbolt is ordered for a specific backset, either 2-3/8 inch or 2-3/4 inch. Deadbolts that adjust in the field include the Brinks Raleigh Series round single cylinder deadbolt and the Brinks Mendocino Series square single cylinder deadbolt, both with 4-way adjustable backset, the Cal-Royal ED500 Grade 3 single cylinder deadbolt with adjustable backset for 1-3/8 inch to 1-3/4 inch doors, and the Falcon D111 Grade 1 deadbolt with adjustable backset.

The Emtek 8550 #2 Sandcast Bronze deadbolt is a bronze, rustic-styled single sided unit offered in Flat Black Bronze, Medium Bronze, and Tumbled White Bronze. For other decorative residential deadbolts, the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt, and the Baldwin Reserve line includes contemporary round and contemporary square double cylinder deadbolts. All three are double cylinder rather than thumbturn-only.

Solid cast material, not a plated shell. Emtek lists the 8550's material and substrate as bronze in the Sandcast Bronze series, with a brass mechanism, which is why the three finishes are bronze tones rather than painted colors. It suits rustic and heavy timber door work where a stamped steel deadbolt would look out of place.

The Emtek 8550 #2 Sandcast Bronze deadbolt is a mechanical, non-electronic unit. If credential or code access is wanted instead, 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 Codelocks CL2210 is an electronic mortise deadbolt.
