Charts and guides, no sign-up

Every chart and guide here is free to read: no sign-up, no download form, no email address required. They are the charts we quote from.

Door handing chartLH, LHR, RH and RHR explained in plan view. The hand is always read from the outside, and getting it wrong is a common reason a replacement arrives useless. Finish codesWhat 626, 630, 689 and 613 mean, which ones are standard on commercial hardware, and which are painted rather than plated. Lock function codesWhat F75 passage, F76 privacy, F82 entrance, F84 classroom and F86 storeroom each do, so the lock behaves the way the door needs. Frequently asked questionsShort answers on ordering, payment, shipping, returns and keying.

Buying guides

One guide per product category: what decides the part number, what we confirm before it ships, and what is stocked or special order. All eight are on the buying guides page.

Where a guide touches code: We supply listed hardware and confirm in writing the part number and options you have chosen. We are not code consultants; your Authority Having Jurisdiction (AHJ) makes the final call.
