The Clearfield® CraftSmart® Splice Closure (CSC) is a rugged, field-friendly dome closure built for maximum versatility and proven long-term reliability in any outside plant environment. Available in three distinct sizes (CSC 250, CSC 500, CSC 750), it gives installers the right capacity for everything from low-fiber-count taps to mid- and high-count splice locations.
Its innovative interchangeable gel-block sealing system eliminates heat shrink and special tools while supporting everything from large express feeds to high drop counts. Built for real-world deployments (aerial, pedestal, handhole, manhole, or direct-buried to 5 meters), CraftSmart delivers GR-771-CORE performance with details crews actually appreciate: an included Multi-Tool, pre-installed flex basket, and easy-access splice trays that make every job faster and cleaner.
