Ships in approx: 1 Business Day


Onyx Plugs are used to fill extra or empty 1/2″ holes in post. The tight tolerance of the collar provides a snug fit. These are often used with Post Side Handrail Brackets, Grab Rail Brackets, or similar relief post holes. Plugs need to be firmly tapped into the relevant 1/2″ hole with a rubber mallet or dead blow hammer.
