Contact RubberDot

RubberDot is a small, independent, ad-supported site — there is no support desk standing by, but a real person reads what comes in to support@rubberdot.com.

A few things this address is genuinely useful for: a calculator that gave you a result you think is wrong (say which tool — the foot & bumper size selector, durometer hardness guide, adhesive bond calculator, grip-dot spacing calculator, furniture-foot load calculator, or anti-slip estimator — and what you entered); a tool you wish existed on the site; an out-of-date fact or broken link in the blog, learn section, or the Rubber & Materials Museum; or a bug in how a page looks or behaves on your device.

There’s no fixed response time to promise, and no ticket number or live chat — email is read and handled as it comes in. If a question is really about a specific product, its exact rating, or a warranty, the manufacturer or retailer involved will have a more authoritative answer than this site can give; RubberDot’s tools produce general estimates, not official figures, and the site isn’t affiliated with any manufacturer or hardware brand.

Before writing in about a tool result, it can help to double-check the numbers you entered — a load, a pad area, an adhesive strength, or a pressure is the most common source of a surprising answer. If it still looks wrong after that, that’s exactly the kind of message worth sending.
