The Ronstan Series 30 Ball Bearing Stand-Up Orbit Block™ is a single sheave stand-up block with a non-swivel head, requiring 2 x 5mm (3/16") fasteners. Engineered for the highest strength-to-weight ratio in its class, the block uses all-composite reinforced polymer materials to eliminate heavy steel components without compromising performance. The precision 2-stage ball bearing system delivers consistent low friction across the full working load range, while the ultra low profile thru-sheave becket keeps bulk to a minimum. Versatile attachment options include lashing, Dyneema® Links, and shackles to suit a wide range of rigging setups.
