Installation Notes

Eye bolts of this type are typically installed by general contractors, electricians, or HVAC technicians securing equipment or routing support lines. Pre-drilling a pilot hole sized appropriately for the thread diameter is recommended to prevent splitting in wood substrates. Ensure the substrate material and thickness can support the stated load capacity before applying any load. Do not exceed the rated 160-pound load limit.
