Cribbing materials consist of wooden or plastic blocks from ______ to ______ inches long.

• A. 8 - 20 long
• B. 16 - 36 long
• C. 12 - 24 long
• D. 20 - 40 long

Answer: (B)

Choosing the right length for cribbing materials is about giving a stable, safely sized bite surface that fits typical stall setups. Blocks that are 16 to 36 inches long provide enough surface area for a horse to brace and grip without points that can poke or twist. This length distributes forces across a larger area, reducing the risk of the block cracking or being yanked loose, and it also keeps the device from extending far enough to interfere with the animal’s movement or create a leverage hazard. Wood or plastic are common because they withstand chewing and weathering and are easy to mount; the 16-36 inch range keeps them practical for installation and maintenance across standard stalls. Shorter blocks may be unstable or break more easily, while longer blocks can be cumbersome and pose safety issues.
