Rockwood 576NB Replacement White Nylon Roller Bumper | 5-Pack

The Rockwood 576NB is the official OEM replacement roller designed specifically for the Rockwood 576 Gravity Coordinator. This high-impact white nylon roller serves as the critical contact point that allows the coordinator arm to glide seamlessly against the door leaf. This 5-piece value pack is the ideal choice for facility managers looking to perform preventative maintenance across multiple fire-rated door assemblies, ensuring reliable closing sequences and long-term hardware performance.

Precision Engineering & Maintenance Features

• Direct OEM Compatibility: Engineered to fit the 576 series gravity coordinator precisely, restoring the unit to its original factory performance standards.
• Durable White Nylon: Made from low-friction, high-strength nylon that provides a quiet door closing operation and prevents the metal coordinator arm from marring or scratching the door finish.
• Bulk Maintenance Value: This package of 5 rollers is designed for high-traffic buildings like schools and hospitals, allowing for quick replacements without the lead time of individual part orders.
• Safety & Compliance: A smooth-rolling nylon bumper is essential for the coordinator to properly time the closing of a pair of doors, which is a critical requirement for fire-rated door safety.
• Simplified Hardware: This pack is designed for maintenance scenarios where the original fasteners are still in good condition. Note that this package does not include the brass screws.
