5.00"L x 5.00"W x 2.00"D. Multilink’s OSP slack storage box is ideal for exterior slack storage applications using small diameter fiber cable. There are two stackable storage spools that allow storage of multiple single fiber cable drops. Both of these spools are removable, which allows additional storage under the spool. This includes three entry points sealed with removable cap plugs, or it can be ordered without holes. The diameter of each entry hole is 1". The box is equipped with a hex bolt, including a retainer that can be secured using a standard 216C type wrench. In addition to the above, the box is also equipped with a provision for a hasp lock. A built-in hinge allows captive and non-captive flexibility.
