What is the maximum number of successive double studs that may be bored?

The maximum number of successive double studs that may be bored is two. This guideline is essential for maintaining the structural integrity of the wall framing while allowing for the necessary passage of plumbing and electrical lines. Boring too many studs in succession can weaken the framing, leading to potential failure under load or affecting the overall stability of the wall.

By limiting the number of bored double studs to two, it ensures that there is enough material left to retain structural support, which is particularly important in load-bearing walls. This rule helps to balance the need for functional routing of systems inside walls with the necessity of preserving the strength and durability of the structure. Thus, selecting two as the maximum is a practical approach to both plumbing requirements and structural safety.
