The ANMV6 is a patented, non-metallic, spring-loaded system from nVent that offers superior safety, ease of installation and improved load transfer for mechanical, electrical and plumbing (MEP) running through firewalls or other opening applications. The ANMV6 helps restore the fire-rated integrity of the opening, while also allowing for easy insertion and removal of MEP components. Additionally, the system eliminates the need for expensive and difficult to install fire-stops. The ANMV6 consists of a spring-loaded blend retainer, a tube shear and two mounting brackets. The retainer is designed to firmly hold up to two cable bundles in the opening, while the tube shear allows for the easy insertion and removal of cable bundles. The two mounting brackets attach the ANMV6 to the firewall opening.
