Table

RMC Dimensions, Threads, Weight

RMC Dimensions, Threads, Weight reference with assumptions and boundary notes.

Reference boundary

Dimensional reference only. Product series, wall thickness, threads, and manufacturer data govern actual conduit use.

Reference table

Reference common RMC trade-size dimensional values, threads, and weight planning data.

Reference basis uses common RMC trade-size dimensional conventions and rounded weight planning values.
