What does One Man, Two Man, Three Man Mean?
When it comes to explaining sizes of quarry rock, you may hear descriptors such as “Half Man”, “One Man” or “Rockery Rock” when referencing sizes. So what do these quarry rock sizes actually mean? How much do boulders weigh?
Most rock suppliers offer extensive sizing options when choosing boulders. Smaller sizes can be more appealing to the eye when it comes to curb appeal, while bulkier boulder sizes are sought out for stability in projects such as erosion control.
Rather than measure each individual stone, they are broken down into separate categories based on rough diameter and weight. Kenco’s Rocklift comes in 3 unique sizes to pick each one of these sizes.
