Using a tape measure and a pencil, mark the locations for your mounting holes. Start with the bottom trim, measure its total length, and find the center. From the center, measure outwards, ensuring that the spacing between balusters does not exceed 4 inches, following the '4-inch sphere rule' for safety. This may require rounding up to the nearest whole number of balusters. Repeat this measurement and marking process for the upper handrail, ensuring corresponding alignment for each baluster.
