Ladder ___ are metal brackets installed on ladders to hold scaffold planks.

• A. Rungs
• B. Steps
• C. Jacks
• D. Locks

Answer: (C)

Ladder jacks are metal brackets that attach to the sides of a ladder to hold scaffold planks, creating a platform for working at height. They’re built specifically to support the planks, so you can lay a stable deck across them and work safely. Rungs or steps are the horizontal pieces you step on when climbing, not used to hold planks. Locks are components that may secure sections or adjust settings but don’t provide the plank-supporting function.
