The Liftmaster 41A5250-1 (also known as 041A5250-1) is a genuine OEM replacement belt assembly specifically designed for 8-foot residential garage door openers. It is a critical drivetrain component for LiftMaster and Chamberlain belt-drive systems, engineered to provide a whisper-quiet alternative to traditional chain drives.
Key Features & Benefits
• 8-Foot Door Specification: This belt is factory-measured and cut to the precise length required for an 8-foot tall garage door. It will not fit 7-foot or 10-foot rail configurations.
• Quiet & Smooth Operation: Made from reinforced polyurethane, the belt is designed to absorb vibration and significantly reduce operational noise, making it ideal for garages located near living spaces.
• Steel-Reinforced Strength: The belt is embedded with structural steel cords to prevent stretching and fraying, ensuring long-term reliability and consistent door travel.
• Easy Installation: This is a one-piece assembly that comes with a pre-installed connector clip, allowing for a direct "drop-in" replacement of a snapped or worn belt.
Compatibility Guide
The 41A5250-1 is a proprietary part from The Chamberlain Group and is compatible with:
• LiftMaster & Chamberlain: Various belt-drive models utilizing a T-rail or square-rail assembly.
• Craftsman: Many Sears Craftsman belt-drive units that share the Chamberlain chassis architecture.
• Specific Models: Commonly used with models such as the WD912KS, WD822KS, and HD600 (ensure your manual specifies part 41A5250-1).
