Betts Industries’ Cam-Latch Manhole offers a high-quality, 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 is up to the task.

Model 8555 is a 20” full opening cam-latch manhole equipped with a quick opening cast aluminum cover.  Nylon wear saddles provide smooth operation for the six aluminum latches.  Robust 5/8” swing bolts are secured to the collar utilizing a mono-lug design and are adjustable to create a positive seal between the cover and collar. The cover incorporates innovative built-in safety latches on each side of the handle that, unlike other designs, do not require add-on brackets to function.  The safety latches will not swing off the cover until the cover is lifted slightly and residual tank pressure is relieved. This ensures a stuck cover will never override the safety mechanism. The manhole satisfies requirements of 49CFR§178.345-5 and §178.347-3.
