Master Lock HDLBA0615/4D – Frequently Asked Questions
1) Will the Master Lock HDLB handleset fit a 2-3/8 inch backset, or do I need to know the backset before ordering?
No need to measure first. The handleset latch is six-way adjustable and covers both 2-3/8 in (60mm) and 2-3/4 in (70mm) backsets, and it handles square-corner faceplates, rounded-corner faceplates, or a drive-in latch. The deadbolt is four-way adjustable: same two backsets, square or rounded corners. One part number covers the common residential prep either way.
2) Can I key this Master Lock handleset to the Kwikset keys I already use on my rental units?
The cylinder is a conventional cylinder cut to the Kwikset KW1 keyway, so it runs on the same key blank as the Kwikset-keyed hardware already on most residential doors. Order it keyed alike (KA) if you want multiple units on one key, or keyed different (KD) if each door gets its own. There is also a key code field at order time if you need it cut to a specific existing code.
3) What is the closest equivalent to the Master Lock HDLBA0615/4D single cylinder deadbolt handleset from another brand?
The Schlage Residential F60 Addison single cylinder keyed entry handleset with Accent lever is the nearest match - it is also a single cylinder keyed handleset with an Entrance function and a Grade 2 rating, the same grade carried on the HDLBA0615/4D. The differences are interior trim and door thickness: the Master Lock handleset uses a ball style interior knob, while the F60 Addison comes with a lever and is rated for 1-3/8 inch to 1-3/4 inch doors. If the opening needs a lever inside rather than a knob, the Schlage is the swap.
4) I need a keyed entry handleset for a door thicker than 1-3/4 inches - what should I use?
The Master Lock HDLBA0615/4D handleset is built around a six-way adjustable latch and four-way adjustable deadbolt set to 2-3/8 inch or 2-3/4 inch backset, but for a heavy door the Weslock 1411 Traditionale Colonial handleset with Eleganti knob is the one to look at - it is a single cylinder unit rated for 1-3/4 inch to 2-1/4 inch doors. If you want a lighter door covered by the same part, the Weslock 2810 Hillcrest single cylinder handleset with Hudson knob spans 1-3/8 inch to 2 inch.
5) Which handlesets look like the Master Lock HDLBA0615/4D but will not lock the door?
Several handlesets in the same style family are dummy or non-keyed units and give you no locking at all, unlike the HDLBA0615/4D, which is keyed and intended for exterior locking applications. The Emtek 3002 Memphis, 3004 Hamilton, 3005 Melrose and 3006 Manhattan brass mortise entrance handlesets are all Dummy function, as are the Weslock 6695 Belmont with Impresa knob and the Weslock 2815 Hillcrest with New Heaven lever. The Schlage Residential JE285 Barcelona with Seville lever is a non-keyed entry handleset. Use those only on inactive or interior leaves, not on the lockable exterior door.
6) We rekey everything to Schlage SC1 - what handleset matches instead of the Master Lock HDLBA0615/4D?
The HDLBA0615/4D uses a Kwikset KW1 keyway with a conventional cylinder, so it will not join an SC1 system. The Kwikset 687AMD SMC Amador single cylinder handleset is built on the SC1 keyway with SmartKey and is a Grade 3 entrance handleset for 1-3/4 inch doors. If you would rather stay on KW1-style SmartKey, the Kwikset 687AMD SMT Amador and the 687BW SMT Belleview are the same Grade 3 entrance handlesets in that keying.
7) The opening needs a double cylinder handleset - what do I order instead of the Master Lock HDLBA0615/4D?
The HDLBA0615/4D is single cylinder, keyed outside with a thumb turn inside, so it will not satisfy a double cylinder requirement such as a door with adjacent glazing. The Baldwin Estates 6542 Tremont double cylinder entry mortise trim is the double cylinder option, rated for 1-3/4 inch doors; the matching 6542 Tremont single cylinder entry mortise trim covers the same 1-3/4 inch door if you keep the thumb turn. Note that both are mortise trim, so the door must be prepped for a mortise lock rather than the bored prep the Master Lock handleset uses.
8) Is the deadbolt single cylinder with a thumbturn inside, or keyed both sides?
Single cylinder. Key outside, thumb turn on the interior side. That is the normal choice for an entry door without glass close to the lock; if local code or an insurer requires key-both-sides because of adjacent glazing, you'd need a double cylinder unit instead, such as the Baldwin Estates 6542 Tremont double cylinder entry mortise trim.
9) Does this handleset come with a lever inside or a knob?
Interior trim is a ball style knob, paired with the exterior handle grip and a separate deadbolt above it. If your job needs a lever inside (ADA-style operation or just tenant preference), look at a lever-trim handleset instead, like the Schlage Residential F60 Addison with Accent lever or the Kwikset San Clemente with Halifax lever interior trim.
10) Is this Master Lock handleset meant for an exterior entry door or interior use?
It is built for exterior locking applications on an entry door: keyed handleset plus deadbolt, entrance function, residential duty. It is not a passage or dummy set, so it is not the right pick for a closet, a pantry, or a non-latching decorative door. For a non-locking look-alike, a dummy handleset such as the Weslock 6695 Belmont or the Emtek 3002 Memphis is the correct type.
11) I'm buying handlesets for a whole building of units - how does this one ship?
It packs four to a master carton, and the keying is chosen at order time, so a property manager can run a building on keyed alike (KA) sets, or split floors into separate KA groups with the key code field. With the KW1 keyway the same key blanks and pinning kit already in a maintenance shop apply.
12) Can I order this handleset without a cylinder so my locksmith can install our own keyway?
Yes. Alongside keyed alike and keyed different, there is a less-cylinder option under the keying choice, which suits integrators and locksmiths putting a house keyway or a small-format interchangeable-style program into the opening rather than the factory KW1 cylinder.
13) What are the alternatives to the Master Lock HDLB handleset if my door is thicker than standard?
The Master Lock HDLB is a residential entry handleset with an adjustable latch and bolt. If you're hanging a thick door, a couple of peers publish wider thickness ranges: the Weslock 1411 Traditionale Colonial handleset covers 1-3/4 in to 2-1/4 in, and the Weslock 2810 Hillcrest covers 1-3/8 in to 2 in. Standard commercial and most residential exterior doors are 1-3/4 in.
14) Can I get the same handleset look with a keypad or smart deadbolt instead of a key?
The Master Lock HDLBA0615/4D pairs a keyed exterior with an interior thumb turn deadbolt. For keypad operation, the Kwikset 815SCEHFL-CP913CNT San Clemente handleset pairs a Halifax lever with a contemporary SmartCode electronic deadbolt and ships with the RCAL latch and RCS strike for 1-3/4 inch doors. On the Yale side, the BYRD226NRRX Assure Lock standalone touchscreen deadbolt with Ridgefield handleset and the BYRD226CBARX Wi-Fi and Bluetooth version both cover 1-3/4 inch to 2-1/4 inch doors, and the BYRD256 CBARX is a key-free Wi-Fi touchscreen with a Ridgefield passage handleset.
15) What handleset should I use if I do not know the backset until I am at the door?
The Master Lock HDLBA0615/4D covers both common backsets on its own - a six-way adjustable latch for 2-3/8 inch or 2-3/4 inch with square, rounded corner or drive-in faces, plus a four-way adjustable deadbolt. If you need that same field flexibility in another line, the Sure-Loc Aspen AN507 single cylinder keyed entry handleset and the Madison MA507 keyed entry handleset both ship with adjustable backset, as do the Sure-Loc Alta AT507 tubular and Coral CR507 handlesets.
16) Is an interconnected lock a substitute for the Master Lock HDLBA0615/4D handleset?
Not directly. The HDLBA0615/4D is a handleset with a separate keyed cylinder and a thumb turn deadbolt, keyed for entry. The Schlage Residential JI18/19 interconnected lock with Torino lever is a Grade 2 passage function unit with a keyed deadbolt for 1-3/8 inch to 1-3/4 inch doors, meaning the lever always retracts freely and only the deadbolt locks - and it has no exterior grip handle. Choose it when code or habit calls for single-motion egress rather than a gripped handleset.
17) I want a solid brass handleset instead of the Master Lock HDLBA0615/4D - what are the options?
The Deltana handlesets are the solid brass alternatives in an entry function: the 803871B Hanover, the 815871 St. Ann and the 825871 Kingston are all entry handlesets in solid brass, and the 810871 Montego covers doors from 1-3/8 inch to 2 inch. Baldwin also offers the Wesley handleset with an Alcott knob (180WYHXATK) or a Carnaby knob (180WYHXCYK), both entrance function, if you want a knob interior like the ball knob on the HDLBA0615/4D.
18) Is there a simpler single cylinder handleset for a 1-3/8 inch door?
Yes. The Pamex FS7P31 Lexington single cylinder handleset in satin nickel is an entry function unit covering 1-3/8 inch to 1-3/4 inch doors. The Master Lock HDLBA0615/4D is set up for residential exterior locking applications with a KW1 keyway; if your keying program is not tied to KW1 and the door is on the thinner side, the Pamex is the straightforward swap.
