Creates a finished edge at gypsum stops around door and window openings and ceiling intersections

J-Bead is designed to cover raw edges of drywall under all window and door casing.

Application(s): Drywall

Requires no joint compound. Rigid vinyl is not a thermal transmitter and helps stop condensation where gypsum board terminates at exterior metal surfaces, such as window frames and mullions. Rust proof and dent resistant.

  • Produces finished edges at panel terminations.
  • Nail or slip on.

Step 1:
Make sure the surface of the drywall is clean and smooth. Avoid using the tapered edge of the drywall board for this application. Measure and cut the J-Bead to length. Dry fit the J-Bead to ensure the optimum fit.

Step 2:
Position the short flange of the J-Bead so that it is facing the room’s interior. Slip the J-Bead over the edge of the drywall until both edges meet. No fasteners are required to attach the J-Bead to the drywall.

Step 3:
Install the drywall equipped with the J-Bead using screws as normal.
