FCL is a corrugated conduit holder made of polyamide 66. It does not contain halogens, is non-flame propagating and available in black.
It is used for all corrugated plastic conduits.
An advantage is the "limit stop" which prevents the corrugated plastic conduit from shifting.
The conduit holder can be secured by using screws and can also be mounted onto a C-rail. The various sizes can be used in combination.
