Claim 1
Independent Claim
131 words
A picket fence assembly, comprising in combination upper and lower horizontal rails each having a plurality of non-circular through-holes therein, a plurality of vertically disposed pickets arranged in mutually parallel relationship between said rails and extending through respectively aligned ones of said through-holes in said rails, said pickets being respectively in said through-holes from an assembly position wherein said pickets are axially movable in said through-holes to a locking position wherein vertical movement of said pickets relative to said rails is prevented, said pickets being provided with transverse through-holes which are in mutual alignment when each of said pickets is in said locking position, and a rigid rod slidably extending through said transverse through-holes in said pickets to prevent rotation of said pickets from said locking positions to said assembly positions.
