The Notch 3/4" Rigging Spring Block is a medium-duty arborist block designed for smooth, efficient rigging operations with working lines up to 3/4” (19 mm) in diameter.
Engineered for strength and durability, it features hot-forged aluminum side plates, precision CNC-machined sheaves, and a two-stage captive spring pin lock for secure, low-profile operation.
Built for complex rigging scenarios, the block’s flared side plates minimize rope twisting, while its wide, concave upper sheave protects anchor slings and distributes load evenly.
Rated at 30 kN working load limit (150 kN MBS), the Notch 3/4" Rigging Spring Block delivers reliable performance in demanding tree care and arborist operations.
