Bufftech Chesterfield Swoop Posts are designed and routed to accommodate the transition between a 6' tall fence section and a 4' tall fence section. The left and right transition corner posts connect the 6' end of the Swoop section to a standard 6' tall Chesterfield section. The transition line post connects the 6' end of the swoop section to a 6' standard Chesterfield section in a line. The end post terminates the 6' end of the Swoop section. All 4' ends of the Swoop section are used with standard 4' Chesterfield posts.
