OSJ Series
The Off Stud Joiner is manufactured specifically for fiber cement siding. The 1-1/4” overlap saves additional installation time and by not joining directly over the stud you can eliminate corner breakout. The joiners creates a solid backing behind the joint producing a better caulk line and holds the bottom edge in line to provide a clean shadow line. Choose the square edge for all fiber cement siding and James Hardie HZ10 siding. Choose the angled edge for James Hardie HZ5 siding.
