Schlage Residential B520283 – Frequently Asked Questions
1) How deep does the deadbolt pocket have to be bored for a Schlage dust box?
Plan on 15/16 inch of depth behind the strike face, since that's the box depth on the B520-283. When retrofitting an older jamb that was just chiseled for a strike plate with no box, the pocket usually has to be deepened and squared out before the box will seat flush and let the deadbolt throw fully.
2) What does a dust box actually do on a deadbolt strike?
It lines the bolt pocket in the jamb. The B520-283 keeps wood chips, drywall dust, and insulation out of the hole so the deadbolt throws its full length every time instead of stopping short on debris. On a wood jamb it also gives the bolt a metal-lined pocket rather than raw wood that crushes and wallows out over years of use.
3) Is the Schlage B520-283 dust box for residential or commercial deadbolts?
Residential. It's a Schlage residential lock part, meant for entry doors on houses, townhomes, and apartment or condo units. For a commercial opening running a Grade 1 deadbolt in a hollow metal frame, you'd be looking at the frame's own factory strike prep rather than a wood-jamb dust box.
4) Does the B520-283 include the strike plate, or just the box?
Just the box. The B520-283 is the dust box alone, the metal cup that lines the bolt hole in the jamb. The deadbolt strike plate and its screws come with the deadbolt or are ordered separately, so if you're replacing a full strike assembly you'll want both.
5) Can I use a Schlage dust box behind an Emtek strike?
Not a match to count on. The B520-283 is dimensioned to a 2-3/4 x 1-1/8 inch Schlage deadbolt strike. Emtek sells its own dust box, the MP6-TUPKDUSTCVR, made for Emtek strikes on key-in-knob passage and privacy sets. Keep the box with the brand of strike you're installing so the box footprint and the plate opening line up.
6) Do I need to order the dust box in a matching finish?
The dust box sits inside the jamb pocket, hidden behind the strike plate once installed, so it isn't a visible finish part on a finished door. Schlage does make many of its residential lock parts finish-specific, so if you're matching a set of hardware across a building, order it alongside the strike it goes behind rather than assuming one box covers every finish.
7) I'm rekeying a whole building of apartment doors, do I need a dust box on every deadbolt?
Not strictly, a deadbolt throws without one. But on units where the jamb pocket is chewed up or the bolt is dragging, dropping in the B520-283 squares the pocket back up and keeps the bolt throwing full depth. It's a cheap line item to stock in quantity when you're standardizing entry hardware across a set of residential units, since the 2-3/4 x 1-1/8 inch strike size repeats across Schlage residential deadbolts.
