Rigging Pulley for 20 mm rope

Next-generation rigging pulley from ISC for 20 mm rope – up to 150% stronger with an innovative Safelock mechanism for maximum safety and ease of use.

ISC's 200 series rigging pulleys represent a revolution in arborist equipment. These pulleys are up to **150% stronger** than previous ISC standard models, thanks to advanced design with hot-forged aluminum frames optimized through stress analysis software. The unique axle/frame interlock design minimizes deformation under extreme loads, providing superior performance in demanding rigging operations.[1][3][4]

The patented **Safelock mechanism** with a low-profile spring lock offers exceptional safety. Press the Safelock button and rotate the axle head 180° to open – a smooth, one-handed operation. In the open position, the pins remain in perfect alignment, eliminating the need for additional adjustments. Once the axle is fully depressed, the head is rotated 180° (in either direction) and the button automatically locks into place.[1][2][3]

Manufactured from hot-forged aluminum with an anodized surface for durability and rope-friendliness. Perfect for professional tree felling and rigging with ropes up to 20 mm in diameter. CE marked and serial numbered with proof testing for reliability.[2][3]
