How It Works
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
