The CenFlex Horse Fence Line Post Bracket for CenFlex Fencing Systems is a CenFlex fence rail accessory. These wood fence post brackets are needed to secure each rail to wood lines and corner posts. CenFlex line fence post brackets have a belt-loop design that allows the CenFlex rail to slip through it for easy tension adjustment and to promote rail flexibility. If the fence rail is hit, this design allows the entire fence line to freely absorb the impact, thus reducing injury to the animal and/or fence. CenFlex line post brackets should be installed on a 4 in. to 6 in. wood line post. These fence post brackets for wooden posts have an HTP-coated steel core for extra strength and durability.
