Abstract: A system and method are disclosed for converting channels manufactured for connection together to produce a straight conduit into channels that may be connected together to produce an effectively curved conduit. A link is described that permits the connection between two channels to be connected with an axial offset, which cumulatively allows a plurality of channels to produce a curved conduit.

Abstract: A catch basin configured to allow selective positioning of the outlet and inlet ports on the side walls of the catch basin's receptacle body. At least one of the receptacle side walls comprise a slide opening having opposing sides. A slide member has a pair of slide edges that slidably engage the sides of the slide opening to substantially close the slide opening. The slide member has a port section and two or more positioning sections, with at least one positioning section located above the port section and one below the port section. The port section has an outlet or inlet port integral therewith or fixedly attached thereto or the port section comprises a mechanism for attaching an outlet or inlet port thereto, such as a port cutout having a removable knockout plate. The slide member has section removal indicators to identify which positioning sections should be removed.

Abstract: A rollable load bearing mat for protecting turf areas from damage caused by weight bearing loads, such as vehicle or pedestrian traffic, configured from a plurality of interconnected mat units having a plurality of spaced apart cell rows comprising a plurality of generally upstanding tubular cell members. The cell members comprise a series of first cell members and adjoining second cell members that, in the preferred embodiment, share a common sidewall and are axially offset. The cell rows are interconnected by a plurality of flexible strap members configured to allow the mat unit to be rolled for ease of handling and installation. The cell member sidewalls and the flexible strap members are configured to provide a substantially open cell member to facilitate plant growth through the mat unit. Connecting mechanisms at the periphery of the mat unit connect with adjacent mat units to form a unitary load bearing mat.
