We manufacture a variety of standard size manholes and handholes. What is considered a handhole? Simply a structure not tall enough on the inside to stand upright. A manhole is one with 6' of headroom or more, so a person can service conduit or equipment inside, while standing.

Our precast concrete standard structures are quite versatile. By adding midsections, the “two-piece” can become taller. They range in size from 2’ x 2’ square, all the way up to 14' x 7'-6" or 13’ x 9’ rectangular vaults that can be made 20’ or taller. We have varying wall, floor, and roof thicknesses to satisfy your loading requirements, ranging from pedestrian to aircraft.

If you have an approximate idea of what size precast concrete manhole or handhole you are looking for, we can quote your exact size and also offer the closest standard size at a savings, so you have choices. Please see the pdf versions of some of our standards sizes on this webpage to download for your project.

Our handholes and manholes are used for traffic signal projects (ITS), underground communication and telephone ductbank systems, electrical substations, new lighting installations, and airport power/telecommunications.
