This document provides installation instructions for Inox® GT/GS/GR/SR series door hardware, including Tubular Latches, Mortise Locks, and Privacy Bolts. The instructions cover various functions such as Passage, Privacy, Dummy, and Half Passage, and detail the process for determining door handing, changing latch bolt direction, and assembling the components.

Function Description:

The Inox® GT/GS/GR/SR series offers a range of door hardware designed for different functional requirements:

Tubular Latch (Passage/Privacy/Half Passage): These latches are used for doors that require a simple latching mechanism.
- Passage Function (L461/L462/L471/L472): Allows free access from both sides of the door at all times.
- Privacy Function (L461/L462/L471/L472): Features a privacy pin on the inside that can lock the door, preventing entry from the outside. An emergency release is typically present on the exterior.
- Half Passage Function (L465/L475): Combines elements of passage and privacy, often used where one side requires a lever and the other a fixed knob or a different mechanism.
Mortise Lock: A more robust locking mechanism that is recessed into the edge of the door. It typically offers enhanced security and can incorporate various functions like passage, privacy, and entry with a key.
- Passage Function (MCF22): Allows free access from both sides.
- Privacy Function (MCF22): Features a privacy function, often with a thumb-turn on the inside and an emergency release on the outside.
Privacy Bolt: A simple bolt mechanism, typically operated by a thumb-turn on the inside, used to secure a door for privacy.

Usage Features:

Door Handing Determination: Clear instructions are provided to determine if a door is Left Hand (LH), Left Hand Reverse (LHR), Right Hand (RH), or Right Hand Reverse (RHR). This is crucial for correct installation of the lock mechanism.
Latch Bolt Direction Change: Detailed steps are given for changing the latch bolt direction for both TL4 latches and MC Mortise Locks, ensuring compatibility with the determined door handing.
Installation Flexibility: The instructions cover various lock types (tubular latch, mortise lock, privacy bolt) and functions (passage, privacy, dummy, half passage), making the document comprehensive for different hardware configurations.
Non-Removable Rose Designs: Specific instructions are provided for installing hardware with non-removable rose designs, often requiring the use of an Allen key for tightening screws.
Lever Orientation: A critical note emphasizes ensuring that levers on both sides are at a horizontal level before tightening machine screws, preventing misalignment.
Privacy Pin Insertion: For privacy functions, the document details how to insert the privacy pin into the latch privacy pin hub.
Mortise Lock Cylinder Orientation: Instructions guide users to ensure the cylinder is in the correct "off-center" position before tightening the set screw.

Maintenance Features:

While the document primarily focuses on installation, some aspects touch upon maintenance:

Set Screw Usage: The frequent use of set screws, tightened with an Allen key, suggests that components can be adjusted or removed for maintenance or replacement if needed.
Component Replacement: The detailed parts lists imply that individual components can be replaced, facilitating repair rather than full unit replacement.
Proper Alignment: Emphasis on correct alignment of levers and latch mechanisms during installation contributes to the longevity and smooth operation of the hardware, reducing the need for frequent maintenance.
