Fiber Dome Closure, 96 Splice Capacity

Compatible with Splice Tray FB25-4000STP24

The FB23-4379-96DE fiber optic dome splice closure is an "all parts" inclusive hermetically sealed splice enclosure designed for ease of assembly and re-entry. The closure is designed with a gasketed split end plate for midaccess cable applications and includes an integrated slack storage basket, interlocking splice trays via a modified keyhole style stacking module, and an easy to install no special tool sealing system.

All major hardware is factory installed to allow for quick field installation. Universal grommets along with compression style lateral or branch cable seals, makes installing the enclosure easy to assemble. The FB23-4379-96DE is a medium capacity closure that can be used in aerial, pedestal, and underground applications. Dome has the capacity to hold up to four splice trays total.

Cleaning your fiber connector end faces and components regularly is crucial for avoiding a total network failure. Ensure your optical fiber system is working properly and prevent major network issues with fiber cleaning kits, pens, fluids, and wipes.
