The Betts 8555 Manway Assembly is a 20-inch full opening cam-latch manhole with a quick-opening cast aluminum cover. Nylon wear saddles provide smooth operation for the six aluminum latches, and robust 5/8-inch swing bolts secured to the collar with a mono-lug design are adjustable to create a positive seal. Built-in safety latches on each side of the handle don't require add-on brackets to function and won't swing off the cover until it's lifted slightly and residual tank pressure is relieved. The manhole satisfies the requirements of 49CFR 178.345-5 and 178.347-3.
