A drum does the same basic job as a cone, marking the edge of a lane or the line of a taper, but it's built for a rougher environment. At 37" tall on a 23" tire-ring base, it's harder to knock over, more visible in a driver's peripheral vision, and holds up better to the wind blast off passing trucks than a cone does.
Most state DOT specs call for drums instead of cones once you're past a certain posted speed or the closure runs more than a day or two. If you're not sure which your job needs, tell us the road type and duration in the notes field.

Drum questions
What is a channelizing drum used for?
Marking a taper or lane edge on higher-speed roads, where a cone is too light to read as a serious barrier and a barricade is more device than the job needs. Drums are heavier, more visible, and hold their position better in wind and truck wake than cones.
Cone vs drum — which one do I need?
Cones for lower-speed, shorter-duration work: parking lots, short lane shifts, event control. Drums for longer-duration work on faster roads, where the extra height and weight matter. Many DOT specs require drums instead of cones above a certain posted speed or job duration.
Do drums need to be reflective?
For any low-light or nighttime work, yes. A 6" reflective collar is standard on most drums sold for road work.
