	** NOTE TO SPECIFIER ** If reviewing substitution requests for compliance with this specification, Marco Group Inc. recommends particular attention to the following issues: Modularity of individual units: Most facilities undergo changes to cabinet layout long before the end of the service life. Marco Group through-bolting, and integrated base with leveling feature allows complete rearrangement of units without damage to individual units. Strength of door/hinge and latch construction: Failure of these components is the most common field service issue among alternative products. Bolt-through metal fasteners provide strength in high usage environments. Replaceable construction for all components: These most frequently-damaged items are easily replaced in Marco Group cabinets, and are engineered to prevent damage to their supporting sides. Impact and abrasion resistance of the thermally-fused laminate surfacing and PVC edge banding: The surfacing and edge banding materials have been selected to withstand the normal wear and tear expected in Institutional use.
