Insight vision 558005 - Adjustable Top Manhole Roller
The Insight Vision 558005 Adjustable Top Manhole Roller is unique in that it has two opposing clamps that grab the manhole ring from underneath. Since the roller is adjustable you can extend the clamps and create a fixed, in place roller that won’t “flip out.” We see this as a safety improvement in addition to a new and innovative top manhole roller.
