The CommScope Splice Tray, 12 Ct, Mini, Heat Shrink (vendor part FAT-FST-HS01, Millennium part 522188), organizes up to 12 heat-shrink fiber splices in a compact footprint for splice closures with limited tray space, such as smaller aerial or pedestal enclosures. Its mini profile lets splicing crews fit more trays into a closure than standard-size trays allow, useful on drop and distribution splicing where full-size trays are overkill. It stacks with other CommScope trays in FOSC and similar closures. Stock it with matching splice sleeves and cable entry kits for a complete small-closure build.
