The fine-tuned design of the Guardian Bull Ring Anchor makes it ideal for personal Fall Arrest, Restraint, or Work Positioning applications. With the increase in no. of lag screws its performance has also improved. The lag screws are 3 in. long and have a 1/4 in. diameter. This Fall Arrest Anchor for applications has a 130 to 420 pounds worker weight capacity range (including clothes, tools, and equipment). For the installation of lag screws, the required pilot hole diameter is 3/16''. The bull ring anchor is corrosion-resistant as it is made from zinc-plated steel and is thus highly durable.
