Important Application & Safety Reminders
Rig and operate blocks only under the direction of a qualified person.
Do not side load the block—use in-line loading only.
Account for shock loading (jerking/impact) when calculating total load.
Inspect regularly for wear, cracks, deformation, and corrosion; remove from service if damage is found.
Never use a block without a legible capacity tag.
