Review on LLDSIMEX Pair - Precision Steel 1-2-3 Blocks: 1x2x3, 23 Holes - High-Quality Industrial Tool by James Vilchez

I purchased these parts to replace two 3" structural parts. They are perfect for that. Their dimensions are exactly 1x2x3 inches. Rust. You must be able to clean them when you receive them. But they need a rust preventive. 2. DO NOT order them with anything else, at least nothing fragile. Board. Heavy blocks of steel with hard edges have survived with little circuit board, well.
