Anchor

The Anchor is an object used to freeze the parts connecting to it in order to prevent it from being either pulled, pushed, or moved in place, as well as parts connecting to it. It is an indispensable part of any ship, platform, space station, ocean base, and other structures and appliances.

Its appearance is a yellow-colored part with an anchor decal on its top side. When clicked to activate, its color will turn red. It will turn back into yellow when clicked again to deactivate.
