Spec. FF-S-760 as follows: one hole, malleable iron - Type I, Style A.; one hole, cold-formed - Type I, Style B; two hole, cold-formed - Type II, Style A. Malleable iron straps and clamp backs shall be heat treated to reduce brittleness.(# D.Individual Conduit Hangers: Shall be one piece, steel construction with zinc finish, designed for installation on the end of threaded rod with compression or bolted clamp for holding conduit.(# E.Spring Steel Box Conduit and Fixture Fasteners: Shall be made of heat treated steel to produce spring action grip and shape retention. Fasteners may be coated with zinc phosphate or other corrosion resistant finish in lieu of galvanized or cadmium plating. Each spring steel fastener shall be catalog listed as suitable for the way it is used. Rods used with spring steel fasteners shall be not less than 1/4-inch in diameter.(# F.Trapeze Hangers: Shall consist of a steel channel suspended horizontally from two or more steel rods which are attached to building structural members. Trapeze hangers shall be assembled from components which are designed, produced and are catalog listed for the intended use. Components of trapeze hanger assemblies, including beam clamps, clevises and brackets used for attaching to the building structure, shall be the product of the same manufacturer. Trapeze hanger components shall not be loaded in excess of the manufacturer's design ratings. In addition, trapeze hangers shall be as follows:(# 1.` ` Rods not less than 3/8-inch diameter.(#` }&0*s's'Ԍ2.` ` Outside dimensions of channel cross section not less than 1-1/2 x 1-1/2 inches.(#` 3.` ` Channel thickness not less than 12 ga.(#` 4.` ` Channel edges at the open side shall be flanged in to produce a "J" or "L" shaped lip in cross section.(#` 5.` ` Threaded attachments to the channel shall be made by use of special self-retaining nuts designed to resist turning when attachments are screwed in. Retention may be accomplished by coil spring or spring clip attachments to the nuts or other approved means.(#` 6.` ` Bolt-assembled, two-piece conduit clamps designed with ears to engage the channel lips may be used on trapeze hangers in lieu of conduit straps.(#` G.Level Adjustment: Support rods for single conduit and trapeze hangers shall include adjustment means for controlling the level of conduits. Where turnbuckles are used, they shall provide a minimum of 1-1/2 inches of adjustment and incorporate locknuts. Where turnbuckles are not used, rods shall be threaded to provide not less than 1-1/2 inches of adjustment.(# H.Perforated Steel Strap: Strap 18 ga or larger and 7/8 inches or wider may be used to support suspended runs of single conduit 3/4 inches or smaller.(# I.Lighting Fixture Supports: Canopies, swivels and stems shall be as follows:(# 1.` ` Suspension kits for fixtures suspended in finished space shall include a deep dish canopy at least 1-1/2 inches deep and 5 inches in diameter, a swivel mechanism which permits stem deflection of 8 degrees (minimum) off vertical in any direction, a stem at least 5/8 inches OD with length appropriate for indicated mounting height, and miscellaneous hardware. Stem and canopy shall be finished in white baked enamel. (#` 2.` ` Suspension equipment for stem-suspended fixtures in unfinished space shall consist of a combination box cover and swivel mechanism with threaded conduit hub. The swivel shall permit stem deflection of 20 degrees (minimum) off vertical. (#` 3.` ` Canopies for stem-mounted fixtures connected to formed sheet metal raceway systems shall be the product of the raceway manufacturer. Sides of the canopy shall be factory stamped to provide a knockout shaped like the raceway profile to achieve a neat, tight-fitting joint where the raceway enters the canopy.(#` 4.` ` Suspension equipment for chain-suspended fluorescent fixtures shall include a combination receptacle and box cover, chains and cord-set. The box cover shall have two chain hooks and two brackets on top side which engage the ears of the outlet box to provide added safety against falling off. Receptacle shall be NEMA 5-15R. Chains shall have a work load rating of 150 lb (minimum), shall have a "Y" yoke for attachment at each end of the fixture, and shall have a corrosion resistant finish. The wiring between the fixture and receptacle shall be a cord set of 3/C, No. 16 (minimum), type SJ cord with a NEMA 5-15P cap. NEMA designations shall be according to NEMA WD6.(#`  PART 3: EXECUTION 3.1INSTALLATION %0*s's'ԌA.General: Install supporting devices as necessary, complying with manufacturer's written instructions, applicable requirements of codes and standards, and according to recognized industry practices.(# B.Conduit Supports: Support conduits which are not embedded, independently and securely, so that no strain will be transmitted to attached boxes when conductors are pulled in.(# C.Supports for Small Conduits: Use one of the following to support single runs of EMT not larger than 2 inches and rigid steel and intermediate metal conduits not larger than 1 inch.(# 1.` ` Cold-formed steel or malleable iron conduit straps(#` 2.` ` Individual conduit hangers(#` 3.` ` Spring steel conduit fasteners (in dry, noncorrosive space only)(#` D.Supports for Large Conduits: Use malleable iron straps or individual conduit hangers for single runs of rigid steel and intermediate metal conduits larger than 1 inch.(# E.Supports for Multiple Conduit Runs: Use trapeze hangers to support two or more conduits running parallel at the same elevation. Anchor each conduit to the trapeze channel with conduit straps.(# F.Supports for PVC Conduits: Use PVC coated, two hole conduit straps to support PVC conduits and PVC jacketed steel conduits.(# G.Conduits and Boxes above Suspended Ceilings: Perforated strap or spring steel fasteners attached to ceiling support wires may be used in lieu of conduit straps to support 1/2-inch and 3/4-inch conduits above suspended ceilings. Attach only one conduit to any one strap or ceiling support wire. Support conduits so they allow the removability of ceiling panels or layin fluorescent lighting fixtures. Provide auxiliary metal crossmembers of adequate strength and stiffness to support outlet boxes installed at locations other than at main ceiling support members. Where outlet boxes for suspended lighting fixtures are attached to and supported from suspended ceilings, distribute the load over the ceiling support members in an approved manner. Support junction and pull boxes above suspended ceilings from the floor or roof structure above.(# H.Methods of Attachment: Use the following methods for attachment to the various parts of the building:(# 1.` ` Expansion bolts for concrete and brickwork(#` 2.` ` Lag screws for wood(#` 3.` ` Toggle bolts for hollow masonry(#` 4.` ` Structural clamps, welded threaded studs, machine screws or bolts for steel(#`  PART 4: MEASUREMENT AND PAYMENT ***************************************************** WHEN A "LUMP SUM" CONTRACT IS USED, DELETE THE TITLE PART 4: MEASUREMENT AND PAYMENT, AND BOTH ARTICLES FROM THIS SECTION.
