What Is a Rolling Offset?
A rolling offset is a conduit, pipe, or tubing bend that changes position in both the horizontal and vertical directions simultaneously. It is commonly used in electrical installations, plumbing systems, HVAC work, and industrial fabrication projects.
Rolling offsets help installers navigate obstacles while maintaining proper routing and alignment of conduits or piping systems.
How Rolling Offsets Work
Unlike a standard offset that moves in only one direction, a rolling offset combines horizontal and vertical displacement. This creates a diagonal path between two points.
The true offset distance is calculated using the Pythagorean theorem before determining the required travel length.
Why Accurate Measurements Matter
- Reduces installation errors
- Minimizes material waste
- Improves conduit alignment
- Saves labor time
- Enhances project accuracy
- Supports code-compliant installations
Common Rolling Offset Applications
| Industry | Application |
|---|---|
| Electrical | Conduit routing around obstacles |

Best Practices for Installation
Verify Measurements
Double-check all dimensions before bending conduit or pipe.
Use Consistent Bend Angles
Maintaining consistent angles improves alignment and appearance.
Plan Around Obstacles
Identify obstructions before starting installation work.
Minimize Excess Bends
Reducing unnecessary bends can simplify installation and improve system performance.
Frequently Asked Questions
What is a rolling offset used for?
