The Betts 8555 Cam-Latch Manhole offers a robust design that meets the demands of transportation and processing industries, whether for railcar or over-the-road, liquid or dry bulk applications. This 20-inch full opening manhole features a quick-opening cast aluminum cover with a lift handle, two padlock tabs, and replaceable nylon wear saddles. Six smooth-operating aluminum latches, attached to 5/8-inch swing bolts secured to the collar with a single-lug design, are adjustable to create a positive seal between cover and collar. Innovative safety latches on each side of the handle will not swing off the cover until it's lifted slightly and residual tank pressure is relieved, ensuring a stuck cover can't override the safety mechanism. The manhole meets the requirements of 49CFR 178.345-5 and 178.347-3.
