Each ISC Flame 5/8” arborist block is individually serial-numbered.
The American National Standards Institute (ANSI) has released the ANSI Z133 safety requirements which apply to arboriculutral operations. Components of a rigging system must be used within their Working Load Limits.
ISC blocks are ANSI compliant when used within the manufacturer Working Load Limits.
A green log weight chart (found in the Samson Rigging Wheel) will aid in determining loads in tree rigging.
The full ANSI Z133 safety requirements are available on our tree care standards page.
