The hemispherical washers (BU1) and cups (BV1) provide a pivotable
action when used with threaded bar. They allow a 10 degree swing
in all directions from vertical and when used in pairs can provide a
locked connection as shown opposite. Typical applications would be
connecting to a roof rafter where the threaded bar needs to be hanging
perpendicular to the floor or for making a ball socket on the legs
of air conditioning support frames to allow adjustability for sloping
roofs.
· Allows a swing of 10° in all directions
