This page shows the sources and review decisions behind the measurements used by ExactFit. Evidence for the exact model is identified separately from verified equivalent-model or same-chassis evidence. Missing values remain Unknown.
Last reviewed: 2026-09-05. 3 retained source records. 0 unresolved conflicts. All inputs required by the cavity calculation are supported; an applicable cutout may replace additive requirements.
Counts use distinct measurement records. Left and right ventilation share one per-side source record.
Some measurements on this page are not supported by an exact-model document. Each affected row identifies the model relationship and supporting evidence.
This is not exact-model documentation. ExactFit applies it only to the measurement above because the retained evidence supports the stated equivalence.

26 9/16". The final reviewed registry supersedes this earlier audit value. Validated Monogram specification value: width_doors_closed_in = 42 in.
Effect on fit result
This measurement supports the width comparison. An applicable cutout can replace additive clearances. If a required input is unknown and no applicable alternative requirement is established, the result is Uncertain unless another known requirement proves Does not fit.
