Glider to 2 blocks is a glider to half-blockade converter discovered by Sergei Petrov on October 8, 2011, used in his later G4 receiver.

The incident glider is converted into a pair of blocks that form half of a blockade. This half-blockade also functions as an LWSS eater, enabling the conduit to be used as a toggleable LWSS gate that can be opened or closed with a single glider in each case. Sending two successive copies of the same glider would break the pattern, but this can be handled in a standard way by 'guarding' it with a bistable switch.
