Have location where we require dozens of 2" raceways approximately 24" long meeting the following requirements.
Requirements:
1. Available in 2" C
2. Non-Metallic
3. Flexible
4. Listed for use within Concrete
5. Listed for Direct Burial
a. Carlon Flex Plus (ENT, A363) is listed for Concrete, but not Direct Burial.
b. Carlon CarFlex (LFNC, A 356) meets all four requirements, but it doesn't have UL Listing above 1" because it doesn't meet UL "crush requirements".
HDPE duct (A353) can't be used due to limited flexibility of size & length.
LFMC (A350) can't be used because of eventual corrosion concerns of metallic liner in the environment.
Does anything exist . . . from anybody?
