Betts 20 in. Aluminum Cam-Latch Manholes w/ Stainless Steel Hardware

Betts Industries’ Cam-Latch Manhole offers a highquality, robust design able to meet the stringent requirements of the transportation and processing industries. Whether it is for railcar or over-the-road, liquid or dry bulk, this manhole fills the requirement.

Model 8555 is a 20” full opening cam-latch manhole equipped with a quick opening cast aluminum cover which has a lift handle, two padlock tabs and replaceable nylon wear saddles. Six smooth-operating aluminum latches attached to robust 5/8” swingbolts are secured to the collar utilizing a single lug design. The hold-downs are adjustable to create a positive seal between the cover and collar. The cover incorporates innovative safety latches on each side of the handle. These safety latches will not swing off the cover until the cover is lifted slightly off the collar and residual tank pressure is relieved ensuring a stuck cover will not over-ride the safety mechanism. Manhole meets requirements of 49CFR §178.345-5 and §178.347-3.
