Miller 417 Permanent D-Bolt Concrete Anchor

Description

Miller Fall Protection

Permanent D-Bolt Concrete Anchor

The 417 is the set-and-forget concrete anchor: a drop-forged alloy steel D-bolt that installs through up to 4 inches of concrete and stays as a permanent, 5,000 lb rated tie-off point wherever recurring work needs one.

The single D-ring configuration gives one worker a dedicated anchorage that outlives the project.
