How to Read a Spec Sheet

The photograph shows the curve of a pull and the light along its edge. The specification describes what happens behind that impression: where the screws land, how far the grip projects and which front it can fit. Both belong to the choice. The less glamorous drawing is often what allows the attractive piece to become part of the room.

Which dimensions answer which questions?

Center-to-center locates a pull's mounting holes; overall length describes its visible footprint. Projection is the distance it stands out from the front, while grip clearance describes the space behind it. Base dimensions establish the mounting area and potential coverage of existing marks. These measurements are not interchangeable, even when a product's nominal size makes them sound similar.

How does the drawing relate to the actual cabinet?

The exact model, size and finish need to match the specification in hand. Front thickness, screw requirements, neighboring openings and any unusual construction then establish whether that variant can work. A full-size outline helps with footprint and clearance; a physical sample adds the grip and seating of the bases. Unresolved mounting details belong with the maker before fabrication or ordering, with the answer retained alongside the current drawing.

What happens when the delivered piece and the sheet disagree?

The first comparison is between the product label, approved schedule and current drawing for that exact variant. A family brochure or an older revision may explain the discrepancy. Remaining stock can stay unopened while photographs of the piece, packaging and conflicting specification give the supplier a clear record. An agreed replacement or exception then belongs in the schedule and installation information, including every affected unit from the order.

A worked example

A pull listed as 8 inches overall may drill at 6 5/16 inches center-to-center and require screws longer than those supplied for a 1 1/4-inch drawer front.

What should be true before you move on?

The exact current product sheet annotated with drilling, projection, clearance, front thickness, fastener, and finish requirements.
