Extreme Max, single use, studding templates are offered in two styles. Take care of both the 15 wide 2.52 pitch tracks, that are most commonly used, or one for the new 2.86 pitch tracks. These new tracks are thinner to save weight, therefore larger sized heads on studs are needed to prevent stud pull through. Both models offer aggressive stud patterns for both single and double backer installations. Simply select the pattern that will work best for your application, use the template to mark and drill with a track drill.
