A riser clamp assembly for receiving and supporting an insulated pipe. The clamp assembly includes a first riser clamp and a second riser clamp. Each of the riser clamps includes a semi-circular body portion extending arcuately between opposite first and second ends and defining an inner cylindrical wall and an outer cylindrical wall extending axial between top and bottom edges. A generally C-shaped flange projects radially from the inner cylindrical wall generally midway between the top and bottom edges to define an axial center opening. A support brace extends radially from the outer cylindrical wall adjacent each end of the body portion for interconnecting the first and second riser clamps around the insulated pipe.

Example aspects of riser support assembly and a method for adjusting a riser support assembly are disclosed. The riser support assembly can comprise a riser support pipe and a mount extending from a side of the riser support pipe, the mount configured to engage a mounting surface and to selectively adjust a height of the riser support assembly relative to the mounting surface.

A mounting bracket for a hydrant that is fully concealed by the hydrant head. The mounting bracket is fastened to the structure and includes tabs which engage the hydrant head to tightly secure the hydrant to the structure. The hydrant head includes a structure engaging periphery such that the mounting screws are fully concealed and protected from the environment.

A retention mechanism provided for use with a first line and a second line comprises a flexible convoluted web, a first conduit, and a second conduit. The first conduit defines a first passageway through the web, and is configured to receive the first line through the first passageway. The second conduit defines a second passageway through the web, and is configured to receive the second line through the second passageway. The first and second conduits are attached to and surrounded by the web such that the web enables movement of the first and second lines when the first and second lines are fixed respectively to the first and second conduits and extend respectively through the first and second passageways.

A fire protection element is useful for the separation of openings passing through walls or ceilings, in particular of line passages. The fire protection element has a molded part made from intumescent material with a plurality of through-openings for the passage of lines which extend in particular parallel to each other from a first side to an opposite second side of the fire protection element. In each case, the through-openings for the passage are tightly sealed relative to flue gas by a membrane.
