Don-Jo 33A-S-CW – Frequently Asked Questions

1) Will the Don-Jo 33A wrap around plate cover the old holes when I convert a 3-3/4 inch backset lockset to a cylindrical lock?
That is exactly what the 33A does. It converts 3-3/4 inch backset locksets to cylindrical locks, wrapping the stile so the old prep is hidden behind the plate. The plate is 6-1/2 by 9 inches, with a 2-1/8 inch hole and a latch prep indent for the new cylindrical lock. Note the new lock has to be a 2-3/4 inch backset, since that is where the hole is punched.
2) My lockset is 2-3/8 inch backset. Can I still use the Don-Jo 33A wrap plate?
No, and this is the number to check before ordering. The 33A hole is punched on a 2-3/4 inch backset, so a 2-3/8 inch backset lock will not line up with the cross bore. 2-3/8 and 2-3/4 are the two common cylindrical backsets, so confirm which one your replacement lock is before you buy the plate.
3) Will a standard 2-1/8 inch bore knob or lever fit through the Don-Jo 33A plate?
Yes. The 33A is punched with a 2-1/8 inch cross bore, which is the standard bore for cylindrical knobs and levers, so a typical cylindrical lockset passes straight through. The indent for the latch prep is formed into the plate edge so the latch face still seats in the door.
4) How thick is the steel on the Don-Jo 33A, and will it hold up in a school or apartment corridor?
22 gauge, .032 inch steel. That is the working weight for commercial wrap arounds: heavy enough to bridge a chewed up stile and take daily traffic in offices, schools, healthcare, retail, and multi tenant residential, while still thin enough that it does not throw off the lock's fit through the door. It is specified as a commercial product, not residential.
5) Do I need to drill the door to install a Don-Jo 33A wrap around?
Not for the lock hole itself. The 33A comes punched with the 2-1/8 inch bore and the latch indent, so it drops over the existing opening and the new 2-3/4 inch backset cylindrical lock mounts through it. The plate wraps the 1-3/4 inch stile and is retained by the lock hardware, so what you are really doing is bringing the old 3-3/4 inch backset prep up to a standard cylindrical prep rather than reworking the door.
6) Is the Don-Jo 33A a lock, or just the plate?
Just the plate. The 33A is a steel wrap around that covers and re-preps the stile; the cylindrical lockset is bought separately. Order the lock as a 2-3/4 inch backset with a 2-1/8 inch bore so it matches the punching in the plate.
7) How much of the door face does the Don-Jo 33A cover, and will it fit a narrow stile door?
The plate measures 6-1/2 by 9 inches, so it needs at least 6-1/2 inches of clear stile face to lie flat, measured from the door edge. On a wide stile hollow metal or wood door that is not an issue. On a narrow stile aluminum storefront door there is not enough face width, and a wrap around of this footprint is the wrong approach.
8) What is the difference between the Don-Jo 33A and a plain filler plate for a worn lock hole?
Different jobs. A filler plate blanks off an opening you are abandoning. The 33A keeps the opening in service: it wraps both faces of the 1-3/4 inch door and carries a 2-1/8 inch bore on a 2-3/4 inch backset, so a working cylindrical lock mounts through it while the old 3-3/4 inch backset prep stays hidden. Pick the wrap around when the door still needs a lock in that spot.
9) What finishes does the Don-Jo 33A wrap around plate come in?
Four to order: antique brass (AB), satin bronze (BZ), polished brass (PB), and satin stainless (S). For a building already standardized on brushed stainless trim, satin stainless is the match; the brass and bronze options are there for older openings where the existing trim is brass toned.
10) Is the Don-Jo 33A handed? Do I order a left or right hand version?
No handing to specify. The 33A is ordered by finish only, in antique brass, satin bronze, polished brass, or satin stainless. The plate wraps the stile symmetrically and the 2-3/4 inch backset punching works either way round, so one part number covers left and right hand doors.
