New Grounded Helicopter Block from DDIN

DDIN Grounded Helicopter Blocks combine the same quality features of both the standard grounded block and standard helicopter block.

The unique Snap Lock fold-away helicopter arm eliminates the need for removing pins to deploy or retract the fly arm, making the DDIN Grounded Helicopter Block ideal for stringing multiple sizes of single overhead conductors where the pilot line will be flown in. These blocks are assembled with a groundbreaking new Gold Standard Grounding Arm mounted directly to the axle.
