1. Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of your CKB Semi-Frameless Bypass Bathtub Door. This product features a durable aluminum frame, 1/4 inch (6mm) ANSI tempered safety glass, and a matte black finish, designed for bathtub openings between 56 and 60 inches wide and 56 inches high. Please read all instructions carefully before beginning installation to ensure proper function and safety.
2. Safety Information
Always prioritize safety during installation and use. The glass panels are made of 1/4 inch (6mm) ANSI Z97.1 certified tempered safety glass, which is designed to shatter into small, blunt pieces if broken, reducing the risk of injury. However, improper handling can still cause damage or injury. Always wear appropriate safety gear, including safety glasses and gloves, during installation. Ensure the installation area is clear and stable. Two people are recommended for handling the glass panels due to their weight and size.

5. Setup and Installation
Careful measurement and preparation are crucial for a successful installation. All measurements should be taken after walls are finished (e.g., tiled). A minimum threshold depth of 2-3/8 inches (60mm) is required for proper installation.

- Confirm the minimum threshold depth of 2-3/8 inches (60mm) is available.
- Gather all necessary tools (e.g., drill, level, measuring tape, caulk gun).

5.2 Track Trimming
The top and bottom guide rails are pre-cut for a 60-inch wall width. If your opening is smaller, these tracks can be trimmed by up to 4 inches to fit. Ensure precise measurements before cutting.

5.3 Installation Steps
Refer to the illustrated step-by-step instructions included in your hardware set pack for detailed guidance. The general process involves:
- Mounting the wall profiles.
- Installing the top and bottom tracks.
- Attaching rollers and handles to the glass panels.

7. Maintenance
Regular maintenance will ensure the longevity and appearance of your bathtub door.
7.1 Cleaning
- Glass Panels: Clean with a soft cloth and a non-abrasive glass cleaner. Avoid harsh chemicals or abrasive pads that can scratch the glass or damage protective coatings.
- Frame and Hardware: Wipe down with a soft, damp cloth. For matte black finishes, avoid abrasive cleaners to prevent damage to the finish.
- Tracks: Periodically clean the top and bottom tracks to remove soap scum, hair, and debris that can impede smooth sliding.
7.2 Waterproofing
The door features a sloped aluminum splashboard designed to prevent leaks. Regularly inspect the silicone sealant around the frame and tracks. Reapply sealant if any signs of wear, cracking, or peeling are observed to maintain a watertight enclosure.

8. Troubleshooting
If you encounter any issues with your CKB Bathtub Door, consider the following:
- Difficulty Sliding Doors: Check the top and bottom tracks for debris. Clean thoroughly. Ensure rollers are free from obstruction and properly aligned.
- Water Leaks: Inspect all sealed areas for gaps or cracks in the silicone caulk. Reapply sealant as necessary. Ensure the sloped splashboard is correctly positioned.
- Loose Hardware: Periodically check and tighten any screws or fasteners that may have loosened over time. Do not overtighten.
