Faucet hole diameter and mounting spread are different dimensions. Match the selected faucet’s shank, fixing hardware, hoses and mounting surface to the basin or countertop drawing before fabrication.

Record the hole diameter, number of holes, centre spacing, deck thickness and fixing access. Check clearance for supply hoses and any waste control. Keep the approved mounting drawing with the worktop or basin order so the product and installation opening stay matched.

A Delta 9113-series product answer identifies a mounting-hole range of 1 1/4 to 1 1/2 inches (32 to 38 mm). That is an example for the named product, not a drilling specification for all faucets or QSW products. See the manufacturer's product information.
| Layout or example | Reference measurement | Buyer check |
|---|---|---|
| Named single-hole kitchen example | 1 1/4–1 1/2 in / manufacturer-stated 32–38 mm | Obtain the chosen model's permitted hole diameter |
| Three-hole centreset example | 4 in / 101.6 mm spread | Measure outer mounting-hole centre to centre |
| Widespread example | 8–16 in / 203.2–406.4 mm spread | Confirm the selected valve and hose layout |
| Deck or basin material | Actual thickness and reinforcement | Verify clamping length and underside access |
Moen distinguishes its 4-inch centreset layout from 8–16-inch widespread arrangements. These are mounting examples, not interchangeable hole patterns. Moen centreset and widespread guidance.
Record each hole's diameter, the distance between centres and its offset from the basin edge or backsplash. Check the faucet body, handle movement and outlet reach above the bowl. A single-hole mixer with an optional cover plate still needs the appropriate shank opening and a plate that actually covers the unused holes.
Keep the tap opening separate from the sink drain, overflow and entire worktop cut-out. Those dimensions serve different parts. The basin drawing and faucet drawing should use the same datum and unit system so a fabricator can compare them directly.
No. Use the permitted opening and fixing details for the selected faucet and mounting surface.
Send your chosen models, installation requirements, destination and quantities. QSW will organise the product specifications, applicable model documents, spare-part schedule and packing proposal with your manufacturing quotation.
