ClarkDietrich metal J-trim is a 
strong, reveal-type galvanized 
steel casing that provides 
maximum corrosion protection 
and neat finished edges to drywall 
terminations around door and 
window openings. It also delivers 
a clean trim line at intersections 
or where gypsum panels abut 
dissimilar surfaces, such as columns 
and window mullions. Hemmed 
edges allow quick installation and 
do not require joint compound.

METAL UTRIM/SPACKLE J
ClarkDietrich U-trim, or Spackle 
J, provides maximum protection 
and clean finished edges on gypsum 
panels around door and window 
openings, and when wallboard 
abuts dissimilar surfaces, such as 
suspended ceilings, beams, plaster, 
masonry and concrete. It’s easily 
installed by sliding trim over the 
edge of the board and nailing/
screwing through the knurled 
(long) flange—which also enhances 
compound adhesion.
