Baldwin Estate 5510 T Strike with Dust Box

The 5510 strike plate itself measures 1-7/8" x 2-3/4", so the jamb needs a face mortise cut to that footprint plus a pocket behind it for the dust box that ships with the strike. The dust box is what lines the latch cavity, so plan on drilling depth for it rather than just routing the plate outline.

A T strike is the narrow-waisted plate shaped like a T, with the lip formed on one side and a reduced body between the two screw ends. The 5510 is that type. It is not interchangeable with a full rectangular ANSI strike, which uses a larger 4-7/8 inch face plate and a deeper frame cut. If the jamb on your door is already routed for a wide ANSI plate, this smaller T strike will not cover the existing mortise.

No. The 5510 is a residential Estate Series strike, sized for residential latch prep, not for commercial cylindrical or mortise locks that expect a full ANSI strike and reinforced frame. For an apartment entry door or a home, it is the right part; for a commercial opening under a spec, use a commercial strike matched to that lock.

Nine finishes: 003 Polished Brass PVD, 031 Non-Lacquered Brass, 055 Polished Nickel PVD, 056 Lifetime PVD Satin Nickel, 060 Satin Brass Brown, 102 Oil Rubbed Bronze, 112 Venetian Bronze, 190 Satin Black and 260 Polished Chrome. Order the strike in the same Baldwin finish code as the lockset it serves, since the strike is the one visible piece on the jamb side and a mismatch shows every time the door stands open. The PVD finishes hold their color; 031 and 102 are living finishes that change with handling.

Brass is the base material on the 5510 strike, which is why it takes the living finishes such as 031 Non-Lacquered Brass and holds up to repeated latching without the lip deforming the way a thin stamped steel strike can.

Yes, the 5510TSTR is sold as a standalone strike and dust box, so you can replace a bent lip or a strike that got chewed up during a lock swap without buying a whole lockset. Match the finish code to the rest of the trim on that door.

The dust box ships with the strike. That is the sheet cup that sits behind the plate and lines the latch hole in the jamb, keeping the latch off raw wood and hiding the cavity. No separate part number to add.

Strikes of this type are not handed as a stocking decision the way a lever is; the plate mounts either way up and the lip does the work on whichever side the latch approaches. What you do need to keep consistent across the units is the finish code and the jamb prep, since the 1-7/8" x 2-3/4" cut and the dust box pocket must be the same on every opening for the plates to sit flush.
