L-Trim is installed after the gypsum panels are already in place, unlike mud-on J, which must be installed during gypsum panel installation. L-Trim is easily attached with screws or nails after the panels are in place. Installation is completed with joint compound for a smooth ready-to-paint surface.
- Hemmed front flange for rigidity.
- Knurled, perforated flange enhances joint compound adhesion.
- Easy to attach and finish.
