What's Inside

Conduit Fill Calculator

Pick EMT or PVC Schedule 40, add wire gauges and counts, and get the fill % against the conductor-count-based limit — with a pass/fail check and a recommended minimum size.

Offset Bends

Angle + rise → mark spacing and shrink, for the standard 10°/22.5°/30°/45°/60° bends.

3-Point & 4-Point Saddles

Clear a single obstruction or a wide one, with the matching center/side bend combination.

90° Stub-Up Deduct

Desired stub height → hand-bender deduct → exact mark position on the conduit.

Box Fill Calculator

Conductors, device yokes, clamp, and grounds → required volume vs. the box's listed capacity.
