Weslock 06600--INSL20 – Frequently Asked Questions
1) Will the Weslock 6600 interior trim fit a 1-3/4 inch entry door?
Yes. The Weslock 6600 interior handleset trim covers a door thickness range of 1-3/8 to 2 inches, so a standard 1-3/4 inch exterior door sits in the middle of the range. That upper end matters on solid wood or built-up doors where a 2 inch slab would defeat trim that stops at 1-3/4.
2) Do I need to re-drill my door for the Weslock 6600, or does it use the existing bore?
It uses standard residential prep. The cross bore is 2-1/8 inches, and the latch faceplate is 1 inch by 2-1/4 inches, which is the common residential mortise for the latch. The description also calls for a 1 inch edge hole and a minimum 5-1/2 inch center to center between the handleset cross hole and the deadbolt cross hole. If your door already carries a handleset with that spacing, no new boring is needed.
3) Does the Weslock 6600 latch work with a 2-3/8 inch backset, or do I need a 2-3/4?
Either one. The latch is adjustable between 2-3/8 and 2-3/4 inch backset, so you set it to whatever your door was bored for rather than ordering by backset. Those are the only two backsets used on residential doors, so one part covers both.
4) What strikes come with the Weslock 6600 handleset trim, and will they cover my existing mortise?
Two strike shapes ship with it: a 2-1/4 inch full lip strike and a 1 by 2-1/4 inch strike, in both radius (round corner) and square corner. Round corner is what most factory pre-machined jambs are routed for; square corner suits a jamb mortised by hand with a chisel. Because both are in the box, you are not picking corner style at the order stage. The strikes take 3 inch screws that reach past the jamb into the framing.
5) Is the Weslock 6600 a complete lockset or just the inside half of a handleset?
Inside half only. The 6600 is interior trim for a Weslock Mansion or Philbrook single cylinder handleset, meaning the knob and the deadbolt turn on the room side plus the latch and strikes. The exterior handle grip and the keyed cylinder are the handleset itself and are ordered separately. Buy this when you are changing the inside look, replacing damaged interior trim, or standardizing interior knobs across a run of units without touching the outside of the doors.
6) Which Weslock handlesets does the 6600 interior trim go with?
The Mansion and the Philbrook exterior handlesets, both in the Molten Bronze collection. It will not adapt to another manufacturer's grip. If the outside of your door carries a Kwikset or Schlage handleset, you need that brand's own interior pack instead.
7) What interior handleset trim works on a 1-3/8 inch door?
The Weslock 6600 interior handleset trim adjusts to a door thickness range of 1-3/8 inch to 2 inch, so a 1-3/8 inch door is inside its range. Among the alternatives, the Schlage Residential JH59 Broadway lever inside trim for a handleset also covers 1-3/8 inch to 1-3/4 inch and is Grade 3 with an Entrance function. The Schlage F59 Accent lever interior pack starts at 1-5/8 inch, and the FC59 Alexandria glass knob interior trim pack starts at 1-5/8 inch as well, so neither reaches down to 1-3/8 inch.
8) Can I key the Weslock 6600 into the rest of my Weslock locks on the property?
The cylinder is a 5 pin in the Weslock keyway, so it keys alike with other Weslock cylinders on the same keyway. If your building is standardized on Kwikset KW1 or Schlage SC1 keys, this will not join that system and you would be carrying a second key.
9) What is the difference between a single cylinder and a double cylinder entry handleset?
Single cylinder, which is what the 6600 trim is built for, means key on the outside and a thumbturn or lock button on the inside. Nobody needs a key to get out. Double cylinder takes a key on both sides, which stops someone reaching through broken glass to turn the bolt but slows an exit in a fire. On an entry with sidelights or glass in the door, that trade-off is the whole decision. This trim is an entry function, so it locks and unlocks from inside without a key.
10) Is the Weslock 6600 rated for commercial use, like an apartment corridor or an office entry?
No. The 6600 trim is a residential product, built for single family and multi-family unit entry doors, side doors, and similar openings. For a commercial opening under a hardware schedule you want a Grade 1 or Grade 2 commercial bored lock, not residential handleset trim.
11) I want a lever on the inside instead of a knob. What are my options?
The Weslock 6600 trim is knob only, in Impressa or Julienne. If a lever is required, say for easier operation with full hands or arthritic grip, look at a lever interior pack from another handleset line: the Kwikset 966BRL Brooklane lever is a Grade 2 entry trim, handed left, and the 966BRNL Breton lever on a square rose is a Grade 2 entry trim built to fit both the Kwikset 687 and 800 series outside trim. Those require the matching Kwikset exterior handleset, not the Weslock.
12) How strong is the deadbolt on the Weslock 6600, and will it resist a saw attack?
One inch throw, with two hardened steel rollers inside the bolt that spin against a blade instead of letting it bite. Paired with the 3 inch strike screws driven into the framing rather than just the jamb, that is the part of the install that actually resists a kick. Weslock states the lock exceeds ANSI A156.2 Grade 2 standards.
13) My door was bored with a 1-5/8 inch top hole instead of 2-1/8. Does the Weslock 6600 still work?
Yes. The top cross hole can be 2-1/8 inch or an optional 1-5/8 inch, while the bottom cross hole must be 2-1/8 inch. Older doors and some manufacturers used the smaller top bore, so this saves filling and re-drilling a slab.
14) Which interior handleset trim packs include a deadbolt thumbturn?
Several of the alternatives bundle the deadbolt side. The Kwikset 966AO Aliso and deadbolt interior pack and the Kwikset 966BL Balboa and deadbolt interior pack are both deadbolt keyed one side, Grade 3 with an Entrance function, and are built for the Kwikset Signature Series 800 and 687 handlesets. The Schlage Residential FC59 Alexandria pack includes a deadbolt thumbturn, and the JH59 Broadway lever inside trim comes with a Collins deadbolt thumbturn. The Weslock 6600 is an interior trim for the Mansion or Philbrook handleset supplied with an adjustable latch and round corner strikes.
15) Are the Schlage F59 and FC59 interior packs keyed like the Weslock 6600?
No. The Weslock 6600 is a keyed single cylinder entry trim using a 5 pin cylinder in the Weslock keyway, locked and unlocked from the exterior with a key. The Schlage Residential F59 Accent lever interior pack and the FC59 Alexandria glass knob interior trim pack are both listed with a Dummy function - they are the inside half of a handleset assembly and do not themselves carry the keyed cylinder. Both are Grade 2. If the requirement is a keyed cylinder in the trim itself, those two are not a substitute.
16) Which interior handleset trims carry a Grade 2 rating rather than Grade 3?
The Weslock 6600 exceeds ANSI A156.2 Grade II. On the Kwikset side, the 966BRL-LH Brooklane lever and the 966BRNL-SQT Breton lever are both Grade 2, while the 966AO Aliso and 966BL Balboa interior packs are Grade 3. Among the Schlage Residential options, the F59 Accent and FC59 Alexandria packs are Grade 2 and the JH59 Broadway is Grade 3. For a rental turn or a facility standardizing on a single grade, that split is the line to sort on.
17) Is the Weslock 6600 solid brass or a plated zinc casting?
Brass substrate, cast solid rather than a plated pot metal shell. That matters on a front door that takes weather and daily traffic, and it is why the finish holds up on exposure. It is finished in oil rubbed bronze or satin nickel.
18) What knob styles and finishes does the Weslock 6600 interior trim come in?
Two knob designs, Impressa and Julienne, each in oil rubbed bronze or satin nickel. That is the full range, four combinations. Match the knob shape to the other interior hardware in the house rather than to the exterior handleset, since this is the piece the occupant actually touches from the inside.
19) Can the Weslock 6600 be set up so the knob and deadbolt release together?
Yes, an interconnect feature is available on the Weslock handleset platform, which lets one motion of the interior knob retract the latch and the deadbolt together. That is what people ask for on a rental or an aging-in-place install where a separate thumbturn gets forgotten on the way out.
20) I need a Satin Nickel interior trim to match the rest of the doors - what matches?
The Weslock 6600 interior handleset trim is offered in Satin Nickel with either the Impressa knob or the Julienne knob, and in Oil Rubbed Bronze with the same two knob designs. The Kwikset 966AO Aliso and deadbolt interior pack is also a Satin Nickel option, Grade 3 with an Entrance function, though it pairs to the Kwikset Signature Series 800 and 687 handlesets rather than a Weslock Mansion or Philbrook exterior.
