Harken offers a variety of removable padeyes for blocks from 57 mm Black Magic,
to custom blocks with maximum working loads of 50,715 lbs (23,000 kg). Bases
swivel so padeyes align to the load. This prevents the reduction of the block's
maximum working load. This unique swivel feature is a Harken exclusive.
