Paddle spacer

Spacers and Spades are normally referred to as Line Blinds. which has the similar function as a Spectacle Blind . The Spade or Spacer is fitted in the line between two flanges and is bolted in place. The Spacer is used when the line is required open and the Paddle Blind or Spade is installed when the line is required blocked or closed. To change it from open to closed, only half the bolts need to be removed and the Spade or Spacer is swapped over. The removed bolts are then installed and tightened. The handle protrudes from the pipe and provides an indicator of whether a Spade or Spacer is installed.For smaller Spades and Spacers it is common for the Spacer to have a hole in the handle and the Spade or Paddle blind to have no hole.
