Emtek 8582US19.RECUS4 – Frequently Asked Questions
1) Does the Emtek 8582 privacy bolt come with a knob or lever, or do I need to buy the passage set separately?
The 8582 is the privacy bolt only. You get the thumbturn, both rosettes, the privacy latch, a strike plate, and the emergency release tool. The knob or lever passage set is a separate order, and it can be any Emtek Brass passage set. If you order a leverset to go with it, you have to give handing on that leverset; the bolt itself doesn't need handing.
2) Will the Emtek 8582 thumbturn privacy bolt fit a 1-3/8 inch bedroom door?
Yes. The 8582 covers 1-3/8 inch through 1-3/4 inch doors as standard, which takes in both an older interior door and a modern 1-3/4 inch slab. Thicker than 1-3/4 inches and you have to call the thickness out on the order, which is why there's a door thickness field at checkout.
3) What backset do I order for an Emtek 8582 privacy bolt, and will it drop into my existing door prep?
Backset is a required choice, 2-3/8 or 2-3/4 inches, so measure from the door edge to the center of the bore before ordering. The cross bore is 2-1/8 inches, the standard residential bore, so an existing bored door usually takes it without redrilling as long as the backset matches. The description calls 2-3/8 inches the standard latch; 2-3/4 is the one you have to specify.
4) How do you get into a bathroom if someone locks the Emtek 8582 privacy bolt from inside?
An emergency release tool ships in the box. The 8582 is a non-keyed privacy function, bed and bath, so there's no cylinder and no key; the outside gets in with the release tool only. For a rental or a facility, keep that tool somewhere the maintenance staff can find it, because a replacement isn't part of the passage set.
5) Should I use a separate thumbturn privacy bolt or just buy a privacy knobset?
A privacy knobset puts the lock in the knob itself. The 8582 splits it: a passage knob or lever that always turns freely, plus a deadbolt-style thumbturn above it on its own pair of rosettes. Two bores instead of one, and two trim pieces to line up, but you get a positive throw bolt on a bed or bath door and you can pair it with any Emtek Brass passage design. If you only have one bore in the door and don't want to drill a second, go with a privacy knobset instead.
6) Can I match an Emtek 8582 privacy bolt to the finish of the door hardware already on my other doors?
Ten finishes: Flat Black (US19), French Antique (US7), Oil Rubbed Bronze (US10B), Pewter (US15A), Polished Brass Lifetime (US3), Polished Chrome (US26), Polished Nickel Lifetime (US14), Satin Brass (US4), Satin Nickel (US15), and Unlacquered Brass (US3NL). The thumbturn finish and the rosette finish are chosen separately, so you can run the rosette to match the existing trim and still change the thumbturn, or keep both the same.
7) What do I have to specify when ordering the Emtek 8582 square privacy bolt?
Four decisions. Backset, 2-3/8 or 2-3/4 inches, required. Thumbturn style: Arched (ARC), Arched Step (ARS), Rectangular (REC), or Rectangular Step (RES). Thumbturn finish and rosette finish, each from the same ten. Door thickness only needs calling out if the door is over 1-3/4 inches. The rosette shape on model 8582 is square, so that one isn't a choice.
8) Is the Emtek 8582 privacy bolt suitable for a commercial building or an office suite?
Emtek lists the 8582 as residential. It is solid brass, non-keyed privacy, and it suits homes, apartments, hotel guest rooms and similar living spaces. For a commercial opening that needs a graded, cycle-rated lock, or anything on a fire door, this isn't the part to spec.
9) Will the square rosette on the Emtek 8582 look right next to my round knob trim?
Model 8582 uses a square rosette, part of Emtek's Square series and a contemporary look. Both faces of the door get one. If your passage knobs sit on round roses, the two shapes will read as a deliberate mix at best; matching the rosette shape to the passage set trim is the cleaner result. The thumbturn itself can be arched or rectangular, stepped or plain, so you can soften the square rose with an arched turn if you want.
10) Does the Emtek 8582 latch come with a round or square corner faceplate?
Both corner styles are covered, round corner or square corner, so the latch faceplate can be matched to the mortise already cut in the door edge. That matters on a retrofit: a router-cut prep takes the radius corner, a chisel-cut prep takes the square. The strike plate ships with it.
11) Is the Emtek 8582 privacy bolt electronic or does it need any wiring?
Purely mechanical. The 8582 is a tubular thumbturn bolt with no electronics, no battery and no cylinder, so there's nothing to wire, program, or key. Throw the turn from inside, release it from outside with the supplied tool.
