Cable Fill

The CPI Cable Fill Table lists RECOMMENDED and MAXIMUM cable fill values for all of CPI’s cable management and cable pathway products. Use the table to find cable fill values when selecting a cable manager or pathway product. The table lists usable area for each cable manager and pathway product so you can calculate cable fill for other types of cable.

The fill table is available in two formats, portable document file (PDF) and Microsoft Excel.

*This table is an easy-to-use spreadsheet that allows you to quickly estimate cable fill values based on your cable specification. The cable fill ratios for cable management and cable pathway products are different, so the products are listed on separate tabs. Simply change the cable size and/or fill ratio (the yellow highlighted fields at the top of the document) to match your cable specification. The spreadsheet automatically calculates fill values up to the limit of the cable manager.

Cable Fill Calculator also available on CPI's Mobile App Suite 

Whether you need values for vertical or horizontal cable managers, cable management rings, cable runway products and more, you will find it here. We have also included a star rating system to help you select the best products for your application. Once you have selected the product and received your cable fill, you then have the option to email your results to yourself or your customer, CPI’s Technical Support, or Distributor for ordering or verification.
