A flexible control joint for use in plastering and stucco applications. Various embodiments of the flexible control joint may be used to form screed walls for different thicknesses of plaster materials applied to adjoining walls or other structures. The walls or other structures may be of similar or dissimilar constructions. Various embodiments of the control joint may be used to form corner arrangements or T-arrangements to achieve desired design effects.

What is claimed is: 1. A flexible control joint, comprising: a first base portion; a first screed wall having a first proximal end protruding from said first base portion and having a first distal end located a first distance away from said first base portion, said first screed wall configured to form a first end wall for a first amount of plaster having a first thickness that is substantially equal to said first distance; a second base portion substantially co-planar with said first base portion; a second screed wall having a second proximal end protruding from said second base portion and having a second distal end located a second distance away from said second base portion and wherein a predetermined difference exists between a magnitude of said second distance and another magnitude of said first distance, said second screed wall configured to form a second end wall for a second amount of plaster having a second thickness that is substantially equal to said second distance; and a flexible attachment assembly attached between said first screed wall and said second screed wall such that said first and second screed walls are in spaced relationship to each other and wherein said flexible attachment assembly facilitates flexible movement between said first and second screed walls; and a first plaster-retainer protruding from said first screed wall; and a second plaster-retainer protruding from said second screed wall; said first plaster-retainer protrudes from said first screed wall at an acute angle away from said first screed wall and wherein said second plaster retainer protrudes from said second screed wall at an acute angle away from said second screed wall. 2. The control joint of claim 1 wherein said flexible attachment assembly member has an accordion-like shape. 3. The control joint of claim 2 wherein said flexible attachment assembly comprises: a first intermediate web attached to said first distal end of said first screed wall, said first intermediate web having a first intermediate web end intermediate said first proximal end of said first screed wall and said second proximal end of said second screed wall and being spaced from said first proximal end and said second proximal end; and a second intermediate web attached to said first intermediate web end and said second distal end of said second screed wall and extending therebetween. 4. The control joint of claim 1 further comprising: at least one first hole in said first base portion; and at least one second hole in said second base portion. 5. The control joint of claim 1 wherein said control joint is fabricated from vinyl material. 6. A flexible control joint, comprising: a first base portion; a first screed wall having a first proximal end protruding from said first base portion and having a first distal end located a first distance away from said first base portion, said first screed wall configured to form a first end wall for a first amount of plaster having a first thickness that is substantially equal to said first distance; a second base portion; a second screed wall having a second proximal end protruding from said second base portion and having a second distal end located a second distance away from said second base portion and wherein a predetermine difference exists between a magnitude of said second distance and another magnitude of said first distance, said second screed wall configured to form a second end wall for a second amount of plaster having a second thickness that is substantially equal to said second distance; a first intermediate web attached to said first distal end of said first screed wall, said first intermediate web having a first intermediate web end intermediate said first proximal end of said first screed wall and said second proximal end of said second screed wall and being spaced from said first proximal end and said second proximal end; a second intermediate web attached to said first intermediate web end and said second distal end of said second screed wall and extending therebetween to facilitate flexible movement between said first and second screed walls; a first plaster-retainer protruding from said first screed wall; and a second plaster-retainer protruding from said second screed wall. 7. The control joint of claim 6 further comprising: at least one first hole in said first base portion; and at least one second hole in said second base portion. 8. The control joint of claim 6 wherein said control joint is fabricated from vinyl material.
