J, L and U Trim are metal trim accessories used to protect free edges of gypsum wallboards. Super Stud metal J, L and U-Trims is used at the termination of a gypsum board finished wall or ceiling. This may be at a door or window opening, at a transition to a different type of finish, or at any edge where a clean, straight, smooth edge is required.
 
 The short leg of Super Stud J-Trim is hemmed for a safe, clean, smooth edge, and both legs are angled for a tight grip on gypsum or other sheathing. The long leg has a slight rib at its base to act as a screed for any finishes that are applied, and the outer edge of the long leg has a small bevel for a smooth tight fit.

J trim metal is used to cap the top edges of skirting, the top and sides of doors, the bottom and sides of windows, and in many cases the top of windows for aesthetics and continuity, also install soffit panels and hold them firmly in place, on inside corners and where the siding meets the soffit or roof at an angle.
