Foreman Night Caps are made of lightweight metal, so they generally can be installed by one person without assistance. A few turns of a single bolt forces disc plates together pressing a rubber gasket against pipe walls as a barrier to unwanted items. Night Caps, however, are not pressure-holding devices.
Field tested by major companies and practical pipeliners, Foreman Night Caps have been proven both durable and long-lasting. The rubber used on the Night Caps can withstand a temperature range from -40° to 260 °F. These Night Caps can also be vented when desirable.
Foreman Night Caps outperform inefficient caps, sacks, sheet iron plates and canvas covers, and are reusable indefinitely. Replacement parts such as gaskets and other components are available.
Foreman Night Caps are available in 1 1/2 to 48 inch sizes and guard against water, mud, rocks, skids, bottles, cans and other accumulation found in pipelines.
