Abstract: A trench drain connection interface for connecting a first trench drain to a second trench drain. The trench drain connection interface comprises a male end, a female end, and at least one protrusion. The male end of the first trench drain has a flange. The female end of the second trench drain has a flange-receiving recess. The at least one protrusion is on at least one of the male end and the female end. The male end of the first trench drain is configured to engage the female end of the second trench drain and when the male end engages the female end, the at least one protrusion prevents at least a portion of the flange from contacting an inner surface of the flange-receiving recess, thereby providing clearance between the flange and the inner surface of the flange-receiving recess.

Abstract: A rebar clamp assembly for engaging a rebar rod is provided that includes a clip and a rebar clamp. The clip has a pair of prongs spaced apart from one another, connected by a bridging portion. Each prong of the pair of prongs includes an inner surface. The rebar clamp has a pair of sidewalls hingedly connected at a first end of the rebar clamp. Each sidewall includes a rebar-receiving notch on an inner surface and a plurality of clip-receiving notches disposed proximate a second end of the rebar clamp on an outer surface. The plurality of clip-receiving notches of each sidewall are configured to engage one of the inner surfaces of the pair of prongs of the clip to bring the pair of sidewalls of the rebar clamp together around the rebar rod.

Abstract: A trench drain assembly includes a cross-bar that can swivel into arcuate guides in the sidewalls of the trench drain assembly and a grate clip assembly for reversibly attaching a grate to a cross-bar, whether of the swivel in type described herein or a cross-bar of a different style.
