Roscoe Moss Company also manufactures and offers a complete line of accessories that work together with its well casing and screen to make installation and maintenance in the field more efficient and cost effective. Well accessories include: welding collars, compression sections, connectors for dissimilar metals, casing guides, cone reducers, landing clamps, casing grips, centralizers or casing guides, and bottom closures. The Rossum Sand Tester, a simple, reliable and easy to use device for accurate measurement of sand content of water, is also available from Roscoe Moss Company.

Casing Grips: Casing grips provide an alternative to elevators for the handling of casings. Using the right tools can make any installation run smoothly.

Centralizers: Centralizers are used to center the screen within the borehole. They should be of sufficient strength and surface area to provide support, yet not impede the installation of gravel. These are conflicting requirements, and some compromise is required. A simple guide, which has proven effective, is manufactured from 5/16 x 2 inch steel, 30 inches long, bent to provide the proper centering distance. This distance or bend is usually the theoretical borehole radius minus one inch. The guides are attached to the screen by welding. Three or four guides are placed equidistantly around the screen at 40 foot intervals.

Bottom Plugs: A bull nose or plug is always attached to the bottom of casing and screen strings installed in gravel envelope wells. Semi-elliptical tank ends, readily available and inexpensive, provide a convenient fulfillment of this requirement.
