One embodiment provides a method and apparatus for suspending air conditioning duct works from a support structure comprising unistrut type support beams which apparatus includes a plurality of support brackets arranged and configured for being slidably interlockable with the interior of the unistrut beam members. The support brackets can be slid inside the interior of the support beam until adjacent a support beam which support beam can be connected to the support bracket. In like manner additional support brackets can be inserted into the interior of the support beam members to be adjustably located next to their respective support rod. In such manner multiple support rods can be used to support a frame member even where the support rods are not symmetrically located along the length of the support beam as the support bracket can be slid/moved inside the support beam until lining up with its respective support rod. Additionally, the entire support framework can be moved relative to the plurality of support rods by sliding the framework relative to the support brackets. In such manner the location of the supporting frame member can be changed without moving the support rods.

A lock tab washer, a pipe hanger, and a method of assembling a pipe hanger are disclosed. The lock tab washer can comprise a washer body, the washer body defining a first side and a second side opposite the first side, the washer body defining a hole therethrough; an edge tab extending from the first side of the washer body, the edge tab define a first section and a second section, the second section bent relative to the first section; a nut tab extending from the second side of the washer body, the nut tab bent relative to the washer body; and a wing extending from the nut tab, the wing bent relative to the nut tab.

A method of assembling a pipe hanger includes inserting a threaded rod through a suspension member; placing a lock tab washer on the threaded rod, the lock tab washer defining an edge tab, a nut tab, and a wing extending from the nut tab; threading a nut on the threaded rod, the nut defining a circumferential side defining a first face and a second face, the lock tab washer oriented between the suspension member and the nut; folding the edge tab over a side edge of the suspension member; folding the nut tab over the first face of the circumferential side of the nut; and folding the wing over the second face of the circumferential side of the nut.

A lock tab washer for a pipe hanger includes a washer body; an edge tab defining a first section and a second section, wherein the first section extends from the washer body and the second section is bent relative to the first section in a first direction; and first, second, and third nut tabs extending from the washer body, wherein each of the first, second, and third nut tabs are bent relative to the washer body in a second direction opposite the first direction.

A hose retainer stand is described. The retainer stand supports and organizes collections of hoses or other flexible members. In many applications, the retainer stand elevates hoses above ground to thereby reduce potential for damage to the hoses. Also described are methods of retaining and supporting hoses by use of the retainer stands.

A cryogenic plumbing support for supporting cryogenic plumbing having a first coefficient of thermal expansion associated with a cryogenic temperature may include a bracket. The bracket may include a second coefficient of thermal expansion approximately equal to the first coefficient of thermal expansion. The cryogenic plumbing support may also include a slide assembly. The slide assembly may include first and second end blocks, at least one slider, and a plurality of rods. The first end block may be coupled in spaced relationship to the second end block by the plurality of rods. The at least one slider may be coupled to the bracket and slidably coupled to the plurality of rods.

A cable mounting system that allows thermal expansion and contraction of cables. The cable mounting system includes straight ladder rack segments and widened ladder rack segments positioned adjacent the straight ladder rack segments. Cable bracket assemblies are mounted to the straight ladder rack segments and saddle bracket assemblies are mounted to the widened ladder rack segments. The cable bracket assemblies secure cables to the ladder rungs of the straight ladder rack segments and allow axial movement of the cables. The saddle bracket assemblies secure the cables on the ladder rungs of the widened ladder rack segments and allow axial and lateral movement of the cables.
