To change it from open to closed, only half of the bolts are needed to be erased and the Spade or Spacer is swapped over. The erased bolts are then installed and tightened. The handle protrudes from the pipe and provides an indicator of whether a duplex Spade or ring Spacer is installed. For smaller duplex Spades and ring Spacers it is common for the ring Spacer to have a hole in the handle and the Spade or Paddle blind to have no hole. For larger sizes Spectacle Blinds can be very bulky and occupy a lot of space so duplex Spades and ring Spacers are preferred.
Spades and Spacers -Identification
Typically a Duplex Spade and Ring Spacer will be identified by the word “SPADE” or “SPACER” stamped on the handle, to clearly indicate what is in the line. Additionally it will be clearly marked with its size, rating, standard, material, heat number.

Duplex Spades and Ring Spacers can be applied in systems where maintenance is not necessary and for applications with large pipe sizes.
