Rockwood 608 Door Silencers for Hollow Metal Frames | 100-Pack

The Rockwood 608 Door Silencers are an essential hardware component designed to eliminate the loud "clanging" associated with doors closing against steel frames. Specifically engineered for hollow metal frames, these silencers feature a cone-shaped design that compresses upon impact, creating a quiet and professional atmosphere. Manufactured from heavy-duty Grey DuraFlex rubber, they provide a long-lasting, resilient cushion that protects both the door and the frame from metal-on-metal wear.

Professional Benefits & Functionality

• Superior Noise Dampening: Absorbs the shock of the closing door to prevent loud bangs and vibrations, which is critical for environments like hospitals and libraries that require quiet operation.
  
• Pneumatic Seal Protection: Beyond noise reduction, these silencers help the door seat firmly against the frame, reducing rattling and improving the performance of latching hardware.
• DuraFlex Material Science: The industrial-grade rubber construction is non-marring and weather-resistant, ensuring the silencers won't become brittle or fall out over time.
• Bulk Maintenance Solution: Supplied in an economical 100-pack, allowing facility managers to perform building-wide hardware upgrades with a single, high-value purchase.
