Frequently Asked Questions
What makes DR‑003 different from surface‑mount door coordinator?
DR‑003 adopts concealed frame‑header integrated installation. The whole mechanism is hidden inside door header and invisible after installation, focusing on high‑end architectural appearance; it needs frame pre‑processing, not fit for simple retrofit renovation projects.
Can DR‑003 be used in coastal salty‑air environment?
Standard material is SUS304; select optional SUS316 grade variant for coastal salt‑air anti‑corrosion working conditions.
Does DR‑003 support custom length?
Yes, DR‑003 supports custom‑cut length ranging from 600mm‑1800mm to match different double‑door opening widths for project requirements.
