The Don-Jo 1-S-CW is not a standard direct match for an Alarm Lock Trilogy T2 cylindrical lock. The Don-Jo wrap plate is made for a 1-3/8" door, 2-3/8" backset, and a 2-1/8" cylindrical lock hole.
The Trilogy T2 cylindrical model is normally specified for 1-5/8" to 1-7/8" door thickness, with 2-3/4" backset standard, and it uses a modified ANSI prep with additional through-bolt holes.
