17 5/8'' (447.7 mm)

17 5/8 inch converts to 447.7 mm center-to-center. To verify existing hole spacing, measure from the center of one mounting screw hole to the center of the other using a steel rule or digital calipers — not from edge to edge. At this scale, a difference of even 5–10 mm matters, so rely on the original appliance documentation rather than a tape measure, since 447.7 mm and the adjacent 457.2 mm (18 inch) standard are easy to confuse in the field.

The 17 5/8 inch (447.7 mm) center is 9.5 mm shorter than the 18 inch (457.2 mm) standard. The 18 inch size is the dominant appliance pull spec and carries a much broader catalog; 447.7 mm appears primarily in European-brand column refrigerators and custom-cabinet specs where a metric dimension close to 448 mm was designed in at the factory. In practice, the choice is rarely discretionary — shoppers at this dimension are almost always matching a documented factory spec rather than selecting from retail options.

A 17 5/8 inch drill-center pull is proportioned for large panel faces: column refrigerator and freezer panels, tall single-door pantries, and built-in wine or dual-zone refrigeration columns typical of European-built custom kitchens. The hardware body extends beyond the 447.7 mm hole spacing, so the overall pull length is longer than the drill center; the specific panel width it suits depends on the appliance model's documented specification rather than a general sizing rule.

At 447.7 mm, the leverage a panel-ready appliance places on the mounting points makes solid construction effectively mandatory. Typical hardware in this category is heavy solid-bar or architectural T-pull design with reinforced through-bolt mounting. The catalog at this spacing is small compared to standard sizes, but appliance pull families that produce a continuous metric range generally include this length built to the same load-bearing standard as their larger appliance pulls.
