Review on Ultimate Strength: Furniture Included with Max Load for Enhanced Thickness by Ryan Turner

They are larger and more powerful than I expected. This would be overkill for something like a crate repair, but great for medium build projects. Reinforcement of the floating steps would be a good help. You have many mounting options (many holes). They are designed for inside corners as there is an inside ledge at the bend which gives more strength but prevents the material from being flattened against the inside.
