The time between when the glue is applied and when it is completely dry is crucial. The only foolproof way to make sure joints don't shift or separate is by using a genuine Hartford Miter Clamp. The clamp is unyielding; locking the casing in place while the glue dries. These one of a kind clamps have been manufactured by a local company in Hartford, Connecticut for over 100 years and they aren't letting up any time soon. Tired of watching the glue dry like a mother hen? A Hartford Clamp would make a great investment.
