Installation & Product Questions

How do I select the correct size?

Use the exact ordering SKU and compare every listed dimension with your existing hardware or installation. Confirm thread size, pin or rope diameter, and overall dimensions before ordering.

What should I verify before installation?

Confirm alloy, dimensions, mating hardware, mounting surface, and the intended marine or architectural application. Use compatible fasteners and follow applicable installation requirements.

What inspection and maintenance are recommended?

Inspect the complete assembly before use and periodically afterward. Replace components showing distortion, cracks, damaged threads, corrosion, excessive wear, or unreliable locking action. Rinse salt and contamination away with fresh water.

Need technical information? Please request product information before ordering if fit, loading, installation, or compatibility is uncertain.
