Cal Spas is the group name on the Cal Spas row 5CH-752 cartridge. Match these numbers: Unicel 5CH-752; Pleatco PCAL60-F2M; Filbur FC-0202. 5-3/16" across, 16-1/8" long, top bar handle, bottom 2” male thread/MPT, 75 sq ft.
Catalog note for PCAL60-F2M: Leisure Time Inc. lists Cal Spas OEM 50753 for 5CH-752 (single retailer source, not shown as OEM). Filbur's catalog prints the Unicel number beside FC-0202 as "5CH-702".
PCAL60-F2M, Filbur note: Pleatco Filbur-to-Pleatco cross reference, PDF p.48 (FC-0202 = PCAL60-F2M, the same Pleatco number Pleatco p.47 gives for 5CH-752); Leisure Time Inc. 5CH-752 page.
5CH-752 is easy to confuse on the Cal Spas table. C-5374 differs by Unicel C-5374, Pleatco PLBS75, Filbur FC-2971, 5-5/16" diameter, 14-13/16" long, top 2-1/8" / open, bottom 2-1/8" / open, note says Filbur lists its FC-2971 equivalent at 5-5/16" x 14-11/16", 65 sq ft. 5CH-502 differs by Unicel 5CH-502, Pleatco PPM50SC-F2M, Filbur FC-0195, 12-1/2" long, 50 sq ft, OEM FIL11100202, note says Unicel prints OEM FIL11100202 on its own line between 5CH-502 and 5CH-752. Two Cal Spas parts retailers resolve it: Hot Tub Outpost lists Cal Spas FIL11100202 as a 50 sq ft cartridge, 12-1/2" long with a handle top and 2" MPT bottom, that replaces FIL11100200 and FIL11100201 and crosses to Unicel 5CH-502 and Pleatco PPM50SC-F2M; Wizard of Spas lists FIL11100202 (and FIL11100201) as the Cal Spas 50 sq ft cartridge with Filbur FC-0195M. Hot Tub Outpost prints the diameter as 5-1/8" (Unicel and Filbur: 5-3/16") and gives the Filbur number as FC-0196, which the Filbur catalog assigns to the 35 sq ft 5CH-352; the Filbur match shown here is the catalog's own FC-0195..
