What is required to prevent planking from sliding off supports?

To prevent planking from sliding off supports, ensuring at least 12 inches of overlap is crucial. This practice creates a secure connection between the planks and the supports, distributing weight effectively and minimizing the risk of slip. Overlapping enhances stability, especially when the surface is subjected to movement or vibration, which can otherwise dislodge planking that is not properly secured or overlapped.

While other options may seem viable, they do not adequately address the primary concern of stability and security. Using a strong adhesive, for example, may not be practical in all contexts and could create more complications when replacing planks. Leaving supports loose compromises safety and increases the risk of movement. Utilizing a supportive beam can aid in providing additional support; however, proper overlap is the most direct method to prevent sliding, ensuring that even if a few supports are compromised, the remaining overlap will maintain stability.
