And don’t waste time placing more 4x4 lumber shores than needed “just to be sure” when there is a better alternative. Post Shores are specifically engineered and tested for shoring applications. Project layouts and spacings become more efficient when based on engineering data, rather than field guesswork.

The Post Shore also includes a Quick-Release feature that relieves pressure so
