Letâs say youâre laying out a floor and want five evenly spaced supports under an 8-foot board. Rather than doing complicated math or measuring repeatedly, just look for the diamonds:
1. Start at 0 inches
2. Place a truss at each black diamond (first at 19.2″, then 38.4″, 57.6″, 76.8″, etc.)
3. That gives you perfect spacing with minimal measuring
Itâs a small feature with big convenience!
