Non-Pressure Manhole Frames and Covers

Non-pressure manhole frames and covers are primarily used for access to large non- pressure storage vessels. Commercial's frames are stamped and holes are gang-pierced to provide the needed consistency required by most tank manufacturers. Frames are either 3 " or 7" (Longneck) deep depending on customer requirements. Because the frames are stamped, there are no weld seams to be concerned about. Frames and covers are made in carbon and stainless steel. In addition, they are stocked in our Ohio and California distribution centers. Click here to view the list of stock sizes.

Reversed Flange Manhole Frame and CoverReversed Flange Manhole
Frame and Cover

Commercial also makes 30” and 36” reverse flange manholes. The 30” diameter manhole allows for more room to install plumbing. The inverted flange and smooth corner radius make it much easier to apply protective coating and virtually eliminate the possibility of uncoated, unprotected areas. The 36” diameter frame comes with 2 rows of studs for mounting sumps or isolation kits. These parts are stocked in our Ohio distribution center.  For more information on these products contact your Commercial customer service or sales representative or click here to view the stocked size.
