The Rockwood 576B is the official OEM replacement part designed to restore the smooth, quiet operation of your architectural door hardware. Crafted from high-density gray rubber, these bumpers are engineered to absorb impact and reduce noise in high-traffic environments. This convenient 5-piece value pack ensures facility managers have a ready supply of critical repair components on hand, preventing equipment downtime and protecting door finishes from damage.

Universal Compatibility & Maintenance Efficiency

The 576B bumper is a "universal" maintenance item within the Rockwood catalog, serving as the direct replacement part for several high-use architectural devices:

• Rockwood 576 Gravity Coordinators: Restores the essential contact point for the coordinator arm to ensure proper door closing sequences.
• Straight Roller Stops: Fits the Model 456 and Model 456L straight-arm stops.
• Curved Roller Stops: Compatible with the Model 455 curved-arm roller stop series.

Key Features & Benefits

• Complete Hardware Kit: Each 5-pack includes solid brass roll pins, providing a secure and permanent installation that resists vibration and heavy use.
• Non-Marring Gray Rubber: The DuraFlex-style rubber is designed to deflect impact without scuffing or leaving marks on wood or metal door leaves.
• Cost-Effective Bulk Pack: Buying in a package of 5 reduces maintenance costs and ensures uniformity across all door openings in a facility.
• Noise Reduction: Replacing hardened or missing bumpers eliminates the metal-on-metal "clack" of coordinators, contributing to a quieter, more professional environment.
