can different sized cables be used in the same speed sleeve?

Thank you for your inquiry about the Hilti CFS-SL GA Speed Sleeves.

Yes, a combination of multiple-sized cables can be passed through the same sleeve, provided that the overall cable fill does not exceed the maximum allowable fill percentage specified in our approval documentation. Please refer to the attached document for more details for case-by-case situation.

If you require further support with this, please feel free to reach out to us through email at NZEngineers@hilti.com and we can help you specifically for the project conditions.

Cheers,
Suman Narayan
