Abstract: A drain support is configured for installation on a surface and to support one or more floor tiles. The drain support includes a base at least partially defining a channel and an outlet, wherein the base defines a base axis, a support dome coupled to the base, wherein the support dome includes at least one aperture formed therein configured to allow fluid to flow from a position outside the dome into the channel, and a pedestal defining a support surface configured to support one or more floor tiles thereon during use, wherein the pedestal is movably coupled to the support dome.

Abstract: A promenade drain for installation on a surface. The promenade drain including a base at least partially defining a channel and an outlet, a connector couplable to the base to form a first joint therebetween, a grate defining one or more apertures, and a frame. The frame, in turn, includes a second sliding surface configured to slide relative to a first sliding surface of the connector, and where the frame can be rotated with respect to the base without influencing the first joint.

Abstract: A roof drain including a flange defining an opening having a central axis, and a throat extending axially from the flange to define a channel having an inner surface therethrough. Where the throat includes a first end generally corresponding with the flange, and a second end opposite the first end, and where the second end is configured to be coupled to a drain outlet. The inner surface of the channel includes a cross-sectional shape taken normal to the central axis, and where the cross-sectional shape continuously and smoothly decreases or remains the same from the first end to the second end.

Abstract: A roof drain including a base defining a channel and an axis, a gravel guard coupled to the base and including a plurality of teeth, where the gravel guard defines a plurality of gullets between the teeth, and a dome coupled to the base, where the dome includes a plurality of ribs, where the ribs define a plurality of gaps therebetween, and where each gap is radially aligned with a corresponding gullet.
