TurboLock TL88 6
Section 3
Installation (Retrofit)
This section details installation steps needed if you are installing the TL88 on a door with a single cutout already made.
To replace an older fixture with a newer one is known as a retrofit. 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 door open or, if needed, the lock and/or parts.
• Remove all parts of any old lock before installing the TL88. 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 off any extra opening.

The TL88 comes already assembled.
Before installation, release the inside
screws and mounting screws to
