Alternate shim compatible with Redi Trench shower pans

The OEM shims Tile Ready ™ sends out with its trench drain shower pans are difficult for a client to remove and replace.  Additionally, they block the flow of water.  This alternative can be slid into the edges of the slot drain, and positioned where they will lift out with the shower drain without the need to be re-adjusted or re-aligned.  My shim provides an arch that water can freely flow under.
