Identifying the Manufacturer
Logo
Brand On Face Notes
Arrow yes “AMEROCK” and other OEM names have been used.
Corbin yes Prior to the brand merger in 1993, the individual brand names “CORBIN” or
Russwin “RUSSWIN” were used. The Emhart logo, a capital E with horizontal arrows
was used during Emhart’s ownership. Some older unit locks have no trademark.
Falcon yes Falcon LY series grade 1 levers were imported from the same
source as PDQ grade 1 levers and are sometimes confused.
LSDA yes Imported; house brand of the IDN companies.
Marks yes
PDQ maybe Latches for these locks bear check marks in a circle
(sic),
and may be private labeled.
Products assembled in the U.S.A. are marked “PDQ”.
Sargent yes Product line numbers 6, 7, 8, 9, 10, 7600, etc. are stamped on the face.
eg., a latch face marked "8" indicates an 8 Line lock.
Schlage yes Same key-in-knob cylinder body used throughout cylindrical lock line.
Only the tailpiece shape and ori en ta tion vary.
Yale yes
5-pin versus 6-pin
Older hardware may have 5-pin cylinders and no room in the handle to retrofit a 6-pin cylinder. Existing
operating keys can be misleading. For ex am ple, some contemporary hardware is pinned to 5-pin keys, even
though the cylinders have six pin chambers. This is re ferred to as “drilled 6, pinned 5”. Try a 6-pin key blank
in the cylinder. It will not seat fully in a 5-pin cylinder.
The face of the latch is the first indicator of manufacturer. Certain brands of latch bolts
a
nd lock chassis are compatible. For example, occasionally an Arrow chassis will be
seen with a Schlage latch bolt. When the knob or lever is removed, the appearance of
the spindle cam, i.e., the cylindrical actuator into which the cylinder tailpiece fits, can be
used to identify the chassis.
