Outward-Opening Round Manway with Cross-Arm Closure

Cross-Arm Cover and Rim Latch

The assembly features a solid round stainless steel cover spanned by a rigid rectangular crossbar arm. One end of the bar pivots on a side bracket welded to the neck collar, the midpoint attaches to a raised circular boss on the cover, and the opposite end engages a swing bolt with a black plastic-grip handwheel.

Weld Neck Collar and Listed Dimensions

The cylindrical neck collar welds directly into the vessel top or shell cutout. The specification schedule lists nominal sizes from 8" to 24" (200–600 mm), a 100 mm collar height, a 3 mm wall thickness, and an internal surface finish of Ra ≤ 0.8 µm.

Alloy and Elastomer Options

Stainless steel construction is offered in SS304 or SS316L, with stainless steel and plastic handle components. Listed perimeter gasket elastomers include silicone, EPDM (noted in the series documentation for -10 °C to +120 °C service), Viton, and NBR, alongside generic food and chemical vessel categories.

Selection and Configuration Checks

While the product photograph depicts a plain cover with a single crossbar handwheel, the generic series schedule on the same page lists 4–6 handles and with-or-without sight glass options. Confirm the exact closure hardware, diameter, collar thickness, and gasket compound before ordering.
