CMI Steel Rigging Block - 3/4"
This arborist block from CMI is a simple, robust rigging block for tree removals. The steel arborist block is very basic in design so it can be offered at a very affordable price. The block has a respectable minimum breaking strength (MBS) of 25,000 lb. The upper sheave and screw are retained when the side-plates are opened to install a rigging sling, which eliminates the possibility of a dropped sheave or screw. The block accepts rigging ropes of up to 3/4" diameter, and tree rigging slings up to 3/4" .
There are other arborist blocks with more advanced features or more polished design, but the basic CMI 3/4" steel arborist block is a great value for the money.
Note: With this style of block, care must be taken that the relatively sharp side plates do not contact the rope.
