350 Post Shores The Post Shore 350 ranges in height from 6’-6” to 11’-5” with a safe working load, depending on the extended length, from 6,445 to 4,400 lbs. Load-tested for supporting plywood decks or reshoring existing structures Don’t take chances with 4×4 lumber shores of unknown and untested capacity. And don’t waste time placing more 4×4 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. A telescoping tube provides rough height adjustment, in 3” increments, using a captured pin. A threaded collar provides fine height adjustment, in a 4” range, using a hinged handle. The Post Shore also includes a Quick-Release feature that relieves pressure so
