Finish
The insert is natural wood. The Gray - Matching Interior option identifies the compatible MDI Signature Shaker collection; it does not mean that the insert is painted gray. The product image shows the complete insert, and the dimension drawing identifies the available sizes.
The nominal cabinet width is not the finished insert width. Measure the clear opening, hinge intrusions, depth and slide clearances before ordering. Confirm the required slides, mounting brackets, fasteners and whether they are supplied with the selected insert.
What is included
The selected roll-out drawer insert. The cabinet, doors and stored items are sold separately. Confirm the mounting components required for the planned installation with MDI.
Installation planning
Installation is required. Confirm compatibility, opening measurements and the fastening method before fitting the insert. Follow the supplied instructions and use appropriate support. Structural load capacity is unspecified.
The uncolored drawing shows the complete configuration and stated dimensions. It is schematic, not a cutting, hardware-position or installation template.
