Spirals are usually manufactured in right hand configuration, but can be made left handed. Spirals may be utilized in pushing, pulling or reversing manner. Spirals can be made with or without an insert (second spiral) depending on the design application.

A single spiral (without insert) is described with the following criteria:

  • The outside diameter (OD)
  • The pitch (distance between adjacent flights). Many Many manufacturers only offer pitch equal to diameter.
  • Bar size, if known. Bar size determines inside diameter.
