Miller 17D-1/ 400 Lb Locking Carabiner Screw Lock Steel

Product Description

The MILLER 17D-1/ is a steel locking carabiner rated for 400 pounds of load capacity, designed for use in fall protection and rigging applications. The screw lock gate mechanism provides a secondary means of closure, reducing the risk of accidental opening during use. At 1 inch in gate opening, it accommodates standard anchorage hardware and lanyards. This hardware is installed by safety professionals, riggers, and contractors working at height in industrial, construction, and maintenance environments.

This carabiner is suited for residential and commercial fall arrest systems, positioning systems, and anchorage connections where a reliable, manually locked connector is required. The steel construction provides durability in demanding jobsite conditions. It is commonly used with safety harnesses, lanyards, and anchor points in overhead or elevated work scenarios where OSHA fall protection standards apply.
