Applies to establishments engaged in the assembly line production of factory built (manufactured) housing such as wood prefab and modular homes, mobile homes and prefab cedar homes when manufactured at a shop or adjacent yard. Sections vary in size up to 80 feet long and 28 or more feet wide. Manufactured homes are built on an assembly line with materials such as plywood, rolls of aluminum, steel I beams, insulation, electric wire, particleboard, lumber, pipes, plumbing fixtures, electrical fixtures, appliances, carpeting, paint and hardware. Assembly may be single line or on a side by side line. After the chassis is built, it is placed on a conveyor where workers lay joists and heating and plumbing lines. Floors are then installed, interior walls are raised and cabinets are installed. Preassembled exterior walls are fastened, the roof is placed, covered, and tie down straps are attached. These homes may be sided with aluminum, vinyl, hardwood fiberboard or natural wood. While the chassis and some other steel parts are welded, the majority of the work is performed with stamping and forming equipment, hand and air tools, joiners, jig clamps, planers, hoists, forklifts and rail conveyors. Other parts may be nailed, riveted, stapled or glued. Furniture and blinds or curtains may then be installed and specialty items such as fireplaces may be added. Units are inspected, then moved to the yard until sold or delivered. Individual work stations may include a mill room, cabinet mill room, sheet metal department or paint and finish departments. Some plants may also have sewing departments where they make curtains, blinds and drapes. This classification includes transporting of the factory built home to the customer's site or a dealer's sales lot when performed by employees of an employer subject to this classification, but excludes set up which is to be reported separately in classification 0517.

This classification excludes establishments engaged in the manufacture of campers and travel trailers which are to be reported separately in classification 2908-02; establishments engaged exclusively in the manufacture of truck canopies which are to be reported separately in classification 2908-03; establishments engaged in the manufacture of fiberglass canopies which are to be reported separately in classification 3511; and delivery and set up performed by an independent contractor which is to be reported separately in classification 0517.

Applies to establishments engaged in the manufacture of factory built campers or travel trailers which are generally not more than 35 feet long and 8 feet wide. This process includes cutting steel I-beams, placing them on a jig and welding the pieces together. Hitches, running gear, and side frames are installed. Subflooring is assembled on a jig and fastened with lag bolts to the frame. Shears, stamping equipment, drill presses and jig clamps are used to perform the work as the pieces are moved by conveyor. Interior and exterior metal panels and trim are spray painted in spray booths or dipped in tanks, using enamel and then hardened by using drying ovens or heat lamps. All electrical wiring, flooring, carpets, heating units, and plumbing fixtures are installed with the use of electrical hand tools, pneumatic wrenches, staplers, and air compressors. Partition walls are then nailed in place with nail guns. Side walls are framed up on a jig and placed on the trailer. Afterwards, the ceiling is nailed in place and the insulation and cabinets are put in place. Sheet metal sides are stapled on and the top is installed. All systems are checked and the trailer or camper is delivered to the distributor's lot. The process of manufacturing a camper is similar except there are no frame rails, axles or hitch involved as a camper has no chassis. Campers are mounted on pickup trucks; travel trailers are fitted with a hitch for towing behind a motor vehicle.

This classification excludes establishments engaged in the manufacture of factory built housing which are to be reported separately in classification 2908-00; establishments engaged in the manufacture of truck canopies which are to be reported separately in classification 2908-03; establishments engaged in fiberglass canopy manufacturing which are to be reported separately in classification 3511; and camper and travel trailer rental/sales agencies which are to be reported separately in classification 3411.

Applies to establishments engaged in the manufacture of wood or metal truck canopies. After the framework is assembled, insulation is cut to size and inserted, electrical wiring is strung, exterior aluminum sheeting or "skin" is cut to size and attached, interior paneling and decorative trim is fitted, doors and windows are installed and electrical clearance lights are attached. Machinery includes, but is not limited to, saws, electrical hand tools, metal cutting and welding equipment, shears, stamping equipment, drill presses, jig clamps, spray booths, pneumatic wrenches, staple and nail guns, air compressors and miscellaneous hand tools. Direct sales to retail consumers or to wholesale dealers by a canopy manufacturer are included in this classification.
