8 TurboLock TL111 PRO
Section 3
Installation (Retrot)
This section details installation steps needed if you are installing the TL111 on a door with a single cutout already
made. Replacing an older xture with a newer one is known as a retrot. If your door has never had a lock or doorknob
installed or otherwise has no cutout, please skip to Section 4.
• For easier installation, have another person help to hold the lock.
• Remove all parts of any old lock before installing the TL111. In some cases, the old strike plate and/or box may be used.
• For your convenience, installation instructions are broken into segments. Read and follow the instructions for both Pre-
Installation and Main Installation.
• If your door happens to have two cut-outs, check the clearance between the two. Make sure there is enough distance so that
you may seal o any extra opening.
