Patent attributes
A fence panel has pickets and rails with slots in the pickets and open bottom U shaped rails. A locking strip slides into the rail and the slots in the pickets to lock the pickets into the rail. The locking strip can be designed with a projecting L portion with a fingers formed between recessed slots along its length such that, at each picket interval, the pickets can pivot around the fingers. Thus, the lock strip allows pivoting of pickets. The rails are designed with a side internal slot with guides to hold the lock strip in place. The rails are further designed with a top internal groove to accept the insertion of a spacer strip that holds the pickets in place and stops them from moving left and right when the top of the pickets do not go through a routed top rail or a supporting middle rail.
