Joint Treatment Beads & Trim
For construction customers across DE, MD, NJ, PA, VA, and Washington D.C.



Successful plastering jobs require quality accessories that are compatible with plaster products. Joint treatment beads and trim help establish the proper thickness of plaster assemblies, reinforce corners and angles, create junctions with other materials, and/or create expansion or control joints. Joint treatment trim and beads can be comprised of metal, vinyl, or a combination of paper and metal.
At Capitol Building Supply, Inc., we know the value of creating tight, reliable bonds with those we serve. That’s why you’ll find an impressive variety of joint treatment beads and trim available* for order or pickup at any of our yards in Delaware, Maryland, New Jersey, Pennsylvania, Virginia, and Washington D.C.
*Inventory varies by location. Call your local yard to confirm specific product availability. If we do not have it in stock at your local yard, we will be glad to order it for you.
