Delaney Traditional - Grade 3 One-Sided Half Bore Deadbolt

There is no outside keyway and no hole bored through the exterior face of the door. The Delaney Traditional one-sided deadbolt is thrown and retracted only from the inside by a thumbturn, so from the outside the door reads as a blank slab. That makes it right for a door you never need to unlock from outside, a back door, a storeroom, a French door leaf, or a decorative application. If anyone has to get in from the outside, you need a single cylinder deadbolt instead.

On the inside face, yes. It uses the standard residential prep: 1-3/4 inch cross bore, 1 inch edge bore, and it works at either a 2-3/8 or 2-3/4 inch backset, which are the two normal backsets on a bored door. The difference is that the outside face is not bored. If you are replacing a two-sided deadbolt on a door that already has a through bore, the old hole on the exterior will still be visible behind the new plate unless it is covered or filled.

The bolt throws a full 1 inch, which is the deep throw you want for a deadbolt and clears a typical door to jamb gap with room in the strike pocket. It comes with a 2-1/4 inch full lip round corner strike, and the latch faceplate is 1 x 2.25 inches with round corners, matching the round corner prep most pre-machined residential doors already have.

It is a deadbolt only, with no latch you can operate by hand from outside, so the door has nothing holding it closed when the bolt is retracted. Pair it with a passage knob or lever on the same door if you want the door to stay shut on its own. The Schlage Residential J10 Builders Basics passage knob is a Grade 3 match with the same 2-3/8 or 2-3/4 adjustable backset and round corner prep, and the Schlage F10 Accent passage lever is a Grade 2 option covering the same 1-3/8 to 1-3/4 inch door thickness.

The Delaney Traditional Grade 3 half-bore deadbolt is a one-sided function with no hole bored through the outside face, so it can only be thrown from the interior. If the door needs to be locked and unlocked from outside, move to a keyed entry assembly such as the Callan Visconti single cylinder handleset with interior trim or the Callan Briona single cylinder handleset with interior trim, both Grade 3. Those give you an outside key cylinder plus a gripping handle, and they require full exterior prep rather than the blind half-bore the Delaney unit uses.

Yes, it would be the wrong choice. The Delaney Traditional half-bore unit is a deadbolt with a 1 inch throw and no spring latch, so it holds the door only when someone throws it from inside; it does not keep a closed door shut on its own. For a hall or closet door that just needs to latch, use a passage set such as the Schlage Residential J10 Builders Basics knob, Grade 3 with a 2-3/8 inch or 2-3/4 inch adjustable backset, or the Schlage Residential F10 Accent lever passage lock, Grade 2 with a dual backset latch. Both fit doors 1-3/8 inch to 1-3/4 inch thick, the same thickness range the Delaney deadbolt covers.

Standard doors from 1-3/8 to 1-3/4 inches thick, which covers typical residential interior doors at 1-3/8 and exterior doors at 1-3/4. Anything thicker than 1-3/4 inches is outside what this deadbolt is built for.

Both. The Delaney Traditional one-sided deadbolt ships with combination screws that work for wood or metal door mounting, so you do not need a separate fastener pack for a hollow metal leaf.

It is a Grade 3 residential deadbolt, so it suits houses, condos, and light multi-family interior use. For a commercial entry or a high traffic opening in a managed property, a higher grade device is the right call. Grade 3 is the residential duty tier under the ANSI/BHMA grading scale.

The Delaney Traditional half-bore deadbolt is a bolt only - it has no handle or knob and no exterior trim. To get bolt and grip in a single assembly, look at the Bravura 913-Savannah, 915-Jacksonville or 971-Austin handlesets, each supplied with a 615 interior plate and 906-Macon interior knob, or the Bravura 973-Montgomery with the 672 interior plate and 939-Charlotte interior lever. All four are Grade 2. Note that these require full through-bore prep on the exterior face, while the Delaney half-bore leaves the outside of the door blank.

No. The Delaney Traditional half-bore deadbolt is Grade 3 residential hardware. The Bravura handlesets - 913-Savannah, 915-Jacksonville, 971-Austin with the 615 interior plate and 906-Macon knob, and the 973-Montgomery with the 672 plate and 939-Charlotte lever - are Grade 2. If a spec sheet or an HOA standard calls for Grade 2 on the entry door, the Bravura handlesets meet that line and the Delaney one-sided deadbolt does not.

It is not built for that application. The Delaney Traditional deadbolt is catalogued as residential hardware, Grade 3, thrown by thumbturn only from the interior with no credential or key on the outside. For a controlled opening, the Paxton PaxLock Pro Galaxy lever latch lock is the different animal: a battery-powered lever lock with a dual frequency 13.56 MHz and 2.4 GHz reader, Bluetooth, AES128 encryption, UL and FCC listing, sized for a 1-3/4 inch door. The Delaney unit can still serve as a secondary interior-only nightlatch on such a door, but it will not read a credential.

Four: US32D stainless steel, US15 satin nickel, US26 polished chrome, and US19 black. If you are matching other openings in a building, those are the standard US finish codes, so you can line them up against existing knobs and levers by code rather than by eye.

They do different jobs on the same style of opening. The Delaney Traditional half-bore deadbolt mounts to a blind exterior face and throws a 1 inch bolt from an interior thumbturn, which is why it is often used as functional decor on a door that should stay shut. The Emtek Select Brass Conical Stem Dark Walnut knob is a passage function knob - it turns from either side and never locks. Choose the Delaney bolt when you need the door held closed against the frame, and the Emtek knob when you only need something to grip and operate.
