Features - Sideplates pivot open to make them easy to load onto sheets, perfect for temporary leads,
line deflection, and static line functions requiring small adjustments. Loop carries primary load
and articulates for a fair lead. Captured Velcro
are aligned. Strap has a reflective tab for easier operation with gloves. Harken composite bearing
technology (ULC) ensures sheaves turn smoothly and maintain efficiency under extreme loading.
Snap-fit Torlon

HL Snatch blocks are supplied by Harken with loops. Loads listed above assume that the standard
Harken-supplied loops are used.
WARNING! Work with a rigger when using alternate spliced loops or fastenings. Knots
or incorrect splices weaken block assembly considerably. Use only Harken-supplied
replacement loops, or work with a qualified rigging supplier when replacing loops.
WARNING! Block loads increase when the line turns at a greater angle. Block loads
double when the line turns 180 degrees. See example above. Use block loading factors.
Select blocks and application carefully.
