What is the maximum height for T-Shore using 4x4" wood?

The maximum height for T-shoring using 4x4" wood is determined by the structural integrity and the loads that the shoring must support. Typically, T-shores made from 4x4 lumber are limited to a height of 8 feet due to their potential to buckle under load if extended higher. This limitation is based on engineering principles regarding lateral stability and load distribution, which ensure safety during rescue operations or while supporting structures.

Using 4x4 wood at heights beyond 8 feet increases the risk of failure, as the shoring may not adequately support the weight of the structure above or resist lateral forces. Therefore, the 8-foot limit is a standard guideline in structural collapse scenarios to prevent collapse and ensure the safety of rescue personnel working in the vicinity.
