A snap-mount blanking panel for an equipment rack or cabinet enclosure has ergonomic grips spaced laterally inwardly and offset forwardly to permit comfortable and reliable mounting and removal of the blanking panel regardless of lateral clearance. A special stacking structure engages the grips in a manner to position a blanking panel, when stacked upon a lower blanking panel, in a fixed and stabilized relation to the lower blanking panel. The stacking features enable stable stacking of multiple units, one on top of another, without requiring external confinement of the stack.
