Questions and Answers
Q: what is a Fed. 161 lock prep
A: That is an exceptional question. A Federal or Government 161 prep, known simply as a #161, is a preparation for a tubular or cylindrical lockset or an auxiliary deadbolt that would be 2-1/8” diameter at 2-3/4” backset with an edge prep of 2-1/4” hige x 1-1/8” wide x 5/32” deep. A link to a template that would be a typical 161 lock prep can be reviewed here:

Any lock prep that deviates from those dimensional properties whatsoever is no longer defined as a #161 prep.

According to Sargent:

The Federal Specifications for Builders Hardware and Door Trim defined the dimensions of door cutouts for various locks. This Federal Government Specification Number FF-H-00106 listed a lock as “Series 86 Cylinder Lock and Latchsets” is now obsolete. The door cutout requirements for this mortise lock became known as an 86 cutout. In the same specification it also defined along with others a 160 and 161 Series Bored Lock and Latch Series. The door preparation for these lock series became known as a 160 and 161 cutout. Although the Federal Standard is obsolete the cutouts are still used today. ANSI standard cutout numbers have replaced these federal cutout numbers. The Federal and ANSI cutouts will be discussed in detail later in this book.
