There are many brands and types of sling hooks (aka slip hooks) to choose from. This line of hooks, from Cartec of Italy, is a little newer than some but is selling very well. Customers trust the European engineering and quality, and they love the price. These hooks are heat-treated and proof-tested with full product traceability. They feature a heavy-duty latch that snaps shut once the hook is properly rigged. In the event you damage the latch, replacement kits are available.
