NESCO Manufactured Products BTTV-31 Single Helicopter Block with Fly Arm
The BTTV-31 series helicopter blocks have an extra-large contoured throat design which allows for safe, smooth passage of swivels, grips, splices and twisted pair conductors (T2 or VR2 ). This series has an optional bolt on stand accessory to further enhance the versatility of the block. Not only will the stand allow the block to be placed upright, but also allows it to be secured at an angle for corners. This block has a highly-visible, easily removable fly arm. The BTTV-31 sheave is supplied with an outside diameter of range of 16" - 46" and is available in urethane lined and polished aluminum. The Helicopter Single Block is available with a spring-loaded grounding arm and roller.
