The UEMSI/HTV DO-6B top manhole roller is made from 2” x 1” x .120 wall steel tubing. Its frame is powder painted blue to protect this part from rust and corrosion. The DO-6B is designed for rough and tough use in sewer cleaning and pipeline video inspection applications.
The 5” polyethylene roller is durable and protects the outside jacket of sewer cleaning hose and video inspection cable. NOTE: An aluminum roller can be substituted for the polyethylene roller on request. Made in the USA.
