FAQ

What is the difference between mechanical and heat-shrink seal?

Mechanical seal uses gel rubber plugs that can be re-opened and re-used when you need to add fibers later. Heat-shrink seal is cheaper but one-time - once heated, it cannot be reopened without cutting.

Can the 12-core closure be buried underground?

Yes. Both models are IP68 rated and rated for direct burial. We recommend the horizontal type for underground and the dome type for aerial.

What is the MOQ for a 12-core closure order?

MOQ is 50 pcs for neutral (blank) boxes. For OEM with your logo, MOQ is 500 pcs. Sample orders of 1-10 pcs are available for evaluation.

Do you provide OEM / private label?

Yes. We can print your logo on the housing and color box, and customize the splice tray layout. Lead time 15 days for 500 pcs.
