The 3M Closure 2 Type 505 ISG (Installed Sealing Gasket) Series is a complete pressure-tight, re-enterable and reusable closure system for protection of communications cable splices across a spectrum of applications. These closures are designed for installation in a variety of aerial, buried or underground outside plant applications and are available in a variety of lengths and diameters.
The new 2-type 505 ISG closure features a factory-installed gasket which allows for quick and easy installation in both new construction and maintenance environments. Because the closures are pressure tight, water cannot invade the splices.
As the demand for broadband services via DSL over imbedded copper networks grows, service providers are having to upgrade/condition their networks, increasing the need for re-entry of the copper pressurized closures. The new closures, which are easy to re-enter and are reusable, can increase productivity and offer virtually zero-cost re-entry. The 2-type 505 ISG closure is a mechanical closure and requires no open flames or heat to install.
DSL is also driving central office vault upgrades and expansions, with service providers requiring flame retardant closures in their central office vaults. The 4-type series line of closures is the flame retardant version of the 2-type series. Previous versions can be upgraded to accommodate the re-enterable and reusable gasket.
