Sargent 99-0007 Cylinder Blocking Ring for 80 Series & PE80 Series Exit Devices

The Sargent 99-0007 Cylinder Blocking Ring is a genuine OEM security accessory designed specifically for Sargent 80 Series and Sargent PE80 Series exit devices. Also referenced as a rim cylinder guard or cylinder protection ring, this component installs around the rim cylinder on compatible Sargent exit devices to secure it firmly in place and shield it against unauthorized removal, tampering, or forced cylinder extraction. It is an essential hardware element for facilities that require a verified, tamper-resistant exit device installation — including schools, government buildings, healthcare facilities, commercial offices, and any high-security application where door hardware integrity is non-negotiable.

Institutional Grade Features & Benefits

• Prevents Unauthorized Cylinder Removal: The blocking ring physically restricts access to the rim cylinder, making it significantly more difficult for unauthorized individuals to extract or manipulate the cylinder on the exit device.
• Tamper-Resistant Security: Engineered to add a critical layer of protection at the cylinder interface — a common vulnerability point on rim-mounted exit devices — helping maintain the overall security rating and integrity of the door assembly.
• Genuine Sargent OEM Part: As an authentic Sargent replacement and accessory component, the 99-0007 ensures precise fit, correct material tolerances, and full compatibility without the risk of aftermarket fitment issues.
• Purpose-Built Compatibility: Designed exclusively for Sargent 80 Series exit devices and Sargent PE80 Series exit devices, ensuring a seamless, factory-correct installation with no modification required.
• Maintains Code Compliance: Helps facilities preserve the integrity of their exit device hardware in line with life-safety and security requirements, supporting compliance with applicable building and security codes.
• Ideal for Retrofit & New Installations: Whether upgrading an existing 80 Series or PE80 Series exit device installation or specifying hardware for a new project, this cylinder blocking ring is the correct OEM solution.
