The JSLT-CG-CU-12B1 is a cap-retained u-channel polymer rail sized to ISO 12B-1 roller chain (pitch 19.05 mm). CU is a mid-range option between CK and U-series: a U-shaped UHMWPE cap snapped onto a flat cold-rolled steel base (no full box-tube). Captures chain laterally without the cost of stainless tubing. The polymer cap is field-replaceable via end-slide. Carbon-steel base ships Zn-plated; SS304 base optional. Custom-machined to your drawing — MOQ 1 piece, FOB Qingdao, quote in 24h.
