How far should rafter holes be from the end of a rafter notch?

The correct distance for rafter holes from the end of a rafter notch is the specified measurement of 2 inches. This requirement is based on building standards and practices that aim to maintain the structural integrity of the rafter. If holes are drilled too close to the end of the rafter, there is a risk of weakening the material, which can compromise the strength of the rafter and the overall stability of the roof system.

Maintaining a distance of 2 inches helps to ensure that the rafter can adequately bear the loads it is subjected to, while also providing enough material around the hole to resist potential splitting or failure. Additionally, adhering to this guideline assists in avoiding any issues with the support and connection points essential in a residential building structure.

The other distances mentioned could potentially lead to structural issues if the hole is placed too close to the notch. Hence, the 2-inch guideline serves as a standard to protect both the safety and performance of the building’s framework.
