发明名称 Drywall edge reveal trim strip
摘要 In conventional drywall construction, a drywall sheet is installed on upright studs with a top edge of the sheet spaced below a top plate or track. A novel rigid trim strip of generally M cross section has a horizontal top lip or first leg resting on the top plate, an upright reveal portion or a second leg extending downward from the first leg alongside the top plate, a horizontal ledge portion or third leg extending outward from the bottom of the second leg and an upright fourth leg extending downward from the third leg alongside the drywall sheet. Finishing compound is applied to mask the fourth leg. The result is a uniform reveal along the upper edge of the drywall sheet.
