The ISC medium arborist block is a great tree rigging block for professional use. The block is secured with a spring-lock. To open, the user simply pushes the pin in, twists, and the side plates may be swung open. The upper bushing and pin are retained, so they can't fall out during use.

The block accepts rigging ropes of up to 5/8" diameter, and tree rigging slings up to 1". The load rating on the block is 33,721 lb MBS (150 kN), with a WLL of 6,600 lb at a 5:1 design factor. The surfaces of this block are rounded to be more rope-friendly. The sheaves are larger than other 3/4" block for a better bend radius in your rigging lines.
