DDIN Helicopter Blocks
DDIN Helicopter Blocks are ideal for stringing multiple sizes of single overhead conductors where the pilot line will be flown in. A unique feature of these blocks is the exclusive “Snap Lock” fold-away helicopter arm, which eliminates the need for removing pins to deploy or retract the fly arm.
