The Trex fence Bracket mad for Trex Fencing has three designs available. The Trex Seclusions fence uses a fence bracket and an angle adapter (angle adapter not to be used for Horizons fence). There are four fence brackets per fence section. The Seclusion angle adapter attaches to the back of the Seclusions fence bracket. One angle adapter equals 22.5-degrees and two angle adapters equals just shy of 45-degrees.
The Trex Horizons fence uses only one fence bracket to support the horizontal top rail. The Horizons horizontal bottom rail does not require fence brackets and uses fasteners for attaching to vertical rails.
Make sure to select the correct fence bracket depending on Seclusions or Horizons style is getting purchased.
