Product Description

The NATIONAL MARKER N233551 is a heavy open S hook manufactured from stainless steel, sized at 2.5 inches. Designed for general fastening, hanging, and rigging applications, this S hook provides reliable corrosion resistance in wet, chemical-exposed, or outdoor environments. The open design allows quick attachment and removal without tools, making it a practical hardware component for service and maintenance crews. Weighing approximately 0.115 pounds per unit, it is suited for light-to-medium load-hanging tasks where a durable, rust-resistant hook is required.

This S hook is appropriate for use in plumbing, HVAC, pool service, and general mechanical applications where components must be suspended, secured, or routed. The stainless steel construction holds up in humid and corrosive conditions common to mechanical rooms, outdoor equipment installations, and poolside environments. It is sold individually and is part of the 2078BC through 2078 series product line.

Installation Notes

Installation of S hooks does not require specialized tools and is typically performed by HVAC technicians, plumbers, or pool service professionals during equipment mounting or component routing. Ensure the load applied does not exceed the rated capacity of the hook and that the hook is fully seated before applying tension. Inspect hooks periodically for deformation or wear, particularly in high-cycle or high-vibration environments.
