This is a custom item, so by placing this order, you verify that all sizes and information are correct as listed. Special Information for SLOPED WEDGE SHIMS: For proper installation, the bottom guide rail of your screen door will need a stable and level surface to rest on. Before ordering, you will need to determine the exact installation location for the screen cassette, which will influence the bottom guide. If the surface is sloped, you will need to level the surface with sill shims. If you are not purchasing a sill transition, you will need to order the wedge shim for use with the traditional bottom guide. If you require a narrow sill transition, you will need to order the wedge shim for use with the narrow threshold transition. If you have a medium sill transition, you will need to order the wedge shim designed for use with the Medium Threshold Transition.
