Description
The 186-C9718 is the widest trimless channel in this group, with a 42 mm bay and a 3000 mm stock length drawn on page 85. The 122-C6214 beside it stops at 20 mm, whereas this profile takes a much broader strip and washes an entire architectural ceiling as one recessed plane. Even at that width the fitting sits out of sight behind a skim coat, and the shared two-step installation drawing and Accessories block show the end caps and fixings used to close the long run.
