Multipoint Lock Preparation
(Except Fire & Steel Doors)
Both the Shootbolt System and the Tongue Bolt systems were designed to be easily modified in height
for use with cut down doors. Therma-Tru multi-point lock hardware is made from a weather resistant
300 series stainless steel, so the number of parts you need to modify for production will determine
what methods you will use to trim them with.

Manual Shootbolt System - Variable Height Option
The Variable Height Shootbolt System is used primarily for double door units. This system requires
a middle extension (MPMESB) and a trimmable top extension in addition to a standard Shootbolt
system gear. The trimmable top extensions and their usage by door height are listed below.

Door Slab Part Number Extension Length Maximum Trim
76.61" 80.55" MPTE8611 15.75" 3.94"
82.52" - 86.46" MPTE8619 21.56" 3.94"
88.43" - 92.36" MPTE8627 27.56" 3.94"
91.38" - 95.31" MPTE8631 30.51" 3.94"
Notes:
1. When cutting the top Shootbolt extension, the faceplate must be cut to the exact length as the distance
from the top of the door to the middle extension faceplate for a precise connection seam.
2. Make sure to have at least 1.24 inches of serrations left on the drive rail to make a good connection.
3. Be sure to have the end of the drive rail pulled even with the faceplate before cutting the top extension.
