Speedplates

The Mr. Manhole system offers a speedplate for every manhole frame

A Speedplate is used to center the B-52 or Six Shooter within the manhole frame. The Standard Speedplate ships with the B-52 Cutter Package and Gold Series Six Shooter Package, however, in certain circumstances you may need a speed plate made for another type of manhole frame.

Because there are a variety of manhole frames in use, it’s important to have the right speed plate for your manhole cutter and location. We offer three different speed plates to ensure you have the right tool for the manholes in your area.

Manhole Frame Styles

Lid Undercut Speedplate

Lid Undercut

The “Lid Undercut” style manhole frames are supported by the Standard Speedplate. If you often replace or repair frames with a larger diameter, these frames are also supported by the Speedplate XL.

Smooth Walled Speedplate

Smooth Walled

In this type of manhole frame there is no lid undercut, which means the standard speed plate would have nothing to grip. It’s a smooth walled frame from top to bottom. We first came across this frame in California, and have named it thus, however, it can also be found in other western states and in coastal areas. Instead of locking onto a lid undercut, the California Speedplate works by tightening laterally as it’s picked up. Once you have made you cut and you begin to pull the manhole up the speed plate will generate laterally tighten pressure against the hardened studs in the face of the unit. It will push out against the smooth walls, lock in, and pull the frame from the road.
