3x2 Minecraft Piston Gate, Best in Class (with instructions / diagrams / how to!)
Channel: Brian Mick

This gate is 1 block wide! It's the narrowest 3x2 gate on youtube. 

I have perfected the 3x2 redstone piston gate.  It is totally hidden from both sides within a standard 3 wide castle wall, works from either side on either pressure plates, buttons, or levers, and it's compact and fast.
