Bosch SPE53C55UC vs GE Profile PDT145SGLWW: narrow openings, different bounds
Both models sit in the 18-inch category, but their documented openings are not interchangeable. The Bosch SPE53C55UC's reviewed screen accepts an opening width from 17 3/4 in to 18 in, with a minimum height of 32 1/8 in and an explicit maximum of 34 7/16 in. The GE Profile PDT145SGLWW asks for 18 in of width, a taller 32 1/2 in minimum height and a 34 3/4 in maximum. On a very low counter the Bosch's lower height screen is the difference; under a taller counter the GE's higher documented maximum is.
| Requirement | Bosch SPE53C55UC | GE Profile PDT145SGLWW |
|---|---|---|
| Minimum opening height | 32 1/8 in | 32 1/2 in |
| Maximum opening height | 34 7/16 in | 34 3/4 in |
| Minimum opening width | 17 3/4 in | 18 in |
| Maximum opening width | 18 in | Not verified |
| Minimum opening depth | 24 in | 24 in |
| Front clearance | Not verified | 23 1/8 in |
| Corner clearance | 6 in | 2 in |
What is equal
Both records screen at a 24-inch minimum opening depth from their published tables, and neither is panel-ready.
Unresolved limits and unknowns
Bosch's own documents disagree about depth: the product page lists 21 2/3 inches, the installation guide 21 5/8, and the spec drawing 24. The reviewed conservative screen is 24 inches; smaller openings require installer review. The Bosch front clearance is not verified. GE's 23 1/8-inch front clearance and 2-inch corner clearance come from its installation guide.
Documented smaller or conditional configurations
These published alternatives never become automatic matches; each needs installer review of the applicable document.
- SPE53C55UC: about 32 1/8 × 17 11/16 × 21 5/8 in (H × W × D) — A linked installation drawing describes smaller minima. Document differences and trim/projection must be checked by the installer; this is not an automatic match. Source
