Baldwin 5300 1-3/8" Extended Full Lip Strike

A full lip strike is the plate that mortises into the door jamb and catches the latch, with a lip long enough to run the full height of the strike opening. On the Baldwin 5300 the lip measures 1-3/8 inches from lip to center, which is the dimension that decides whether the latch clears the jamb and rides onto the lip. You need the extended lip when the jamb face sits back from the door edge, such as a thick casing, a heavy stop, or a jamb that has been built out, so a standard short lip would leave the latch striking wood instead of metal.

The strike plate itself is 1-7/8 by 2-1/4 inches, so the jamb needs a mortise matching that footprint plus the pocket behind it for the latch. If the jamb already carries a 1-7/8 by 2-1/4 inch strike, the 5300 drops into the existing mortise. Anything cut for a smaller or T-strike prep will need to be enlarged.

No. This is a residential strike from Baldwin's Estate line. Fire rated openings need a strike that is part of a listed assembly, so for a labeled door in an apartment corridor, a stairwell, or a commercial building, specify a commercial strike matched to the lockset's listing instead of this one.

That is the case this part is for. The extended lip carries 1-3/8 inches from the lip to the center of the strike, so it reaches out over a jamb face that sits back from the door edge and gives the latch a metal ramp to close against instead of hitting casing or trim. If the problem is instead that the door has sagged vertically or the latch is short of the strike front to back, an extended lip will not correct it; that is a hinge or a longer backset issue.

Eight finishes: 003 Polished Brass PVD, 031 Non-Lacquered Brass, 055 Polished Nickel PVD, 056 Lifetime PVD Satin Nickel, 102 Oil Rubbed Bronze, 112 Venetian Bronze, 190 Satin Black, and 260 Polished Chrome. Those are Baldwin's own finish codes, so ordering the strike in the same number as the lockset or handleset already on the door gives you a match. Worth knowing: 031 Non-Lacquered Brass and 102 Oil Rubbed Bronze are living finishes that darken with handling, while the PVD finishes hold their appearance, so mixing a PVD lock with a non-lacquered strike will drift apart over time.

The 5300 full lip strike is not handed in itself, but the lip projects to one side of the plate, so it has to be installed with the lip running toward the door stop on the side the door swings from. Order one strike per opening and orient it on install; there is no separate left hand and right hand part number.

Brass is the material, which is what lets the lip be dressed or lightly filed on site to line up with a latch that sits proud, and it holds a plated finish rather than a painted one. It is a residential-duty part from Baldwin's Estate series, not a commercial Grade 1 strike.

Order it as a separate line. The 5300EFLS is a replacement and upgrade strike, so you specify it by finish code alongside the lockset when the standard strike shipped with the lock does not suit the jamb. One strike covers one opening.
