One straight arm across a rectangular cover

A single straight arm spans the rounded rectangular cover and pairs with one handwheel. The assembly drawing also identifies a swing bolt, bracket and back hinge support. This simple arm arrangement distinguishes the product from the linked-frame rectangular manway, which uses a different set of closure and support parts.

Materials and the illustrated seal

The frame and cover list 304 or 316L stainless steel options. The illustrated gasket is silicone, while the series description also lists other seal materials. A replacement seal needs the correct rectangular profile and corner geometry as well as the required compound; material name alone does not define a matching part.

Four size rows for layout checks

The exact drawing lists 150×250, 185×235, 200×280 and 230×330 mm sizes. It gives L1 and L2 separately, with a listed height H of 80 mm. Compare the selected row and labelled views when checking the tank opening, surrounding space and replacement collar dimensions.

A tank-side installation layout

The product description places this design mainly on the side of tanks and containers. Its tank interface is welded. Leave room around the arm and handwheel for access, and account for cover movement when locating nearby fittings. Routine checks should include the visible closure parts and gasket seating area.
