Blocks Features and Benefits

Wood Shell Blocks are used with polypropylene or synthetic rope. The 4” blocks have a 1/2” (1.3 cm) diameter rope maximum; the 5” blocks a 5/8” (1.6 cm) maximum; and the 6” blocks a 3/4” (1.9 cm) maximum.

Single blocks are fitted with a swivel hook; double and triple block with a loose, flat hook. Swivel hooks are not recommended on double or triple blocks. The double and triple blocks are fitted with a special live line pin so they can easily be handled with an alligator stick (Cat. No. 4FGQ).

Nylon Blocks are light-weight and self-lubricating. The nylon blocks will handle 1/2” (1.3 cm) diameter rope and smaller.>/p> WARNING: DO NOT EXCEED THE WORKING LOAD LIMIT.
