What is the required endbearing for wood lintels?

The correct answer regarding the required endbearing for wood lintels is 1 1/2 inches. This requirement is based on building codes and structural guidelines that dictate how much of the wood lintel must be supported at each end. Proper endbearing is critical for ensuring that the loads above the lintel are effectively transferred to the supporting walls or structures.

Having at least 1 1/2 inches of endbearing gives sufficient support to the lintel so that it can safely hold the weight it is designed to bear without risk of failure. This standard helps in preventing issues such as sagging or cracking that could arise from insufficient support.

This requirement is essential in construction practices to maintain structural integrity and safety within a building. Other options provided, such as wood preservative, flashing, and 6 inches of endbearing, do not meet the specific guidelines for the endbearing of wood lintels.
