Why are cribbing block ends painted with different colors?

Why are cribbing block ends painted with different colors?

• A. To indicate different lengths
• B. To indicate the type of wood used
• C. To identify the supplier
• D. To reduce weight

Answer: (A)

The main idea here is using color as a quick visual cue to identify block length. In cribbing, you stack blocks to create a stable support under a load, and getting the right height depends on using blocks of the correct lengths. Painting the ends in different colors lets you instantly tell which blocks are which length, so you can sort them and build the stack with uniform pieces. This minimizes the chance of mixing lengths, which could leave gaps, cause tilting, or make the crib unstable. It also speeds checks on-site and helps you spot damaged or mismatched pieces at a glance. Color coding isn’t about wood type, supplier, or weight—those factors wouldn’t help you quickly verify the exact length you’re using in the stack.
