What are these round corner pieces used for?
Round corner hole covers are designed specifically for Diamond Cut applications surrounding round columns. Each set includes 8 units of the 6"-12" round corner and 8 units of the 14"-20" round corner, giving you complete coverage for column penetrations on your job site.
Are these OSHA compliant?
Yes. These round corner covers meet OSHA 1926.502(i) requirements for floor opening protection, providing secure, high-visibility coverage for column-adjacent openings on construction sites.
How do the round corners work with Diamond Cut covers?
Round corner pieces are used in combination with our Diamond Cut hole cover sets to fill the curved gaps that form where a Diamond Cut cover meets a round column. Together they provide complete, OSHA-compliant coverage of the floor opening.
What sizes are included in each set?
Each set includes 16 pieces total — 8 round corner pieces sized for 6"-12" applications and 8 round corner pieces sized for 14"-20" applications.
What material are these made from?
Round corner pieces are made from durable, high-impact polypropylene plastic. They're reusable across multiple projects and feature high-visibility safety orange coloring for maximum jobsite visibility.
