Grating Collars (GPC), also known as Pipe Penetration Collars, are designed to easily enclose unwanted openings, gaps, and penetrations found in walking-working surface areas.

The GPC-6 is designed to encircle 6” openings on grating and deck plate. Each collar effortlessly bolts to the surface from the topside of the grating, using either a J-bolt or L-bolt; therefore, no welding or scaffolding is required. The GPCs bolt-in design is not only easy to install but is also easy to unbolt and remove in case a rework is required.

The GPC-X is used to extend the GPC-6 for larger openings.

Both are manufactured from our rigid, noncorrosive polyurethane, making them resistant to outdoor exposure and harsh environments.
