Description The 100PFC Steel C-Post is the parallel flange channel (C-section) end post for concrete sleeper retaining walls. Where the 100UC H-Post has two channels (for accepting sleepers from both sides), the 100PFC C-Post has a single channel — making it the correct choice for the ends of a retaining wall run, corners, or any position where only one side of the post will hold sleepers. A typical retaining wall needs two C-Posts (one at each end) with H-Posts at intermediate spacings. Both types are concreted into the ground before sleepers are installed.
