How we work
LatchDen is a research desk, not a test lab. We read manufacturer documentation, installation manuals, standards and owner reports, then write down what holds up across all of them. We never claim to have bench-tested a lock we have not, and no manufacturer pays for placement here. Where we earn a commission, it is stated on the page.
