How It Works

Hemispherical cups (BV1) and washers (BU1) provide a pivotable action when used with threaded rod. They allow a 10-degree swing in all vertical directions, and when used in pairs can provide a locked connection.

Typical applications include connecting to a roof rafter, where the threaded rod needs to hang perpendicular to the floor, or for making a ball sock on the legs of air conditioning support frames to allow adjustability for sloping roofs.

Features & Benefits

  • Allows a swing of 10┬░ in all directions
  • Prevents the need to bend threaded rod
  • Provides pivotable element for adjustment
