in the desired orientation and provide the support for the items that are stored on the various storage containers advantageously the design facilitates the assembly by a relatively unskilled user in particular once the first slat is positioned in a leveled orientation and is attached to the underlying wall subsequent slats can be attached quite easily in succession without further measurement and construction thus in a relatively short time period with relatively few calculations and engineering a user can assemble a full slat wall assembly in addition the relative ease of installation coupled with the relatively low cost of manufacture renders the slat wall assembly well suited for renovation as well as new construction in both residential and commercial applications referring to fig7 a the invention further comprises trim assembly 70 trim assembly 70 includes base bracket 72 and finish bracket 74 base bracket 72 includes a first leg 76 and a second leg 78 the legs are joined in the embodiment shown into an u201c l u201d shape in the embodiment shown the base bracket comprises a single material which is formed into the desired orientation of course various embodiments having different shapes are likewise contemplated wherein the resulting function is similar to that of the base bracket finish bracket 74 is.
