More about these tools

The cap over a door sill is the threshold. The ornamental plate around a handle is the escutcheon. Every page here is one drawing of a window, a door, a lock or its hardware, with a numbered ring on each part. Open Study to read every name, with a line on what the part does. That is often enough to order the right replacement.

To make the names stick, switch to Find it or Name it, and missed parts come back at the end of the round. Each drawing prints blank or labeled. Names follow manufacturer glossaries and reference articles read on the date each page shows. Where the trade has two names for one part, both are accepted.
