Abstract: An assembly includes a first block including a first end; and a second block assembled with the first block at a same height as the first block, the second block including a second end facing the first end of the first block. The first block and the second block are connected to the assembly such that there is no structural connection between the second end of the second block facing the first end of the first block.

Abstract: Various implementations include a duct coupler including a body, a first and second arm, and a first and second tooth. The body has a first end that faces a first axial direction, a second end that faces a second axial direction, and a wall. The first and second arm each have a fixed end coupled to the second end and free end axially spaced apart from the fixed end. Each of the free ends are resiliently urgable in a radial direction. The first tooth is coupled to the first arm, and the second tooth is coupled to the second arm. The teeth are shaped such that, when the teeth are engaged with a corrugation of a corrugated duct, the teeth allow the duct coupler to move in the first axial direction with less axial force than moving the duct coupler in the second axial direction.
