Description
The C12 Railing Base Flange is the standard post base for FastClamp guardrail and other structures. The upright drops into the socket and is held by two grub screws; the flange bolts to a concrete floor, steel deck or kerb through its fixing holes.
Use it at post centres that suit the design load of the railing. FastClamp’s technical data page gives maximum post centres by tube size and load; if in doubt, send our technical team the run length and we will confirm the spacing.
