Application Scenarios
Wooden & Fire‑Rated Double‑Door Installations
DR‑003 concealed overhead gate‑selector is optimized for wooden, luxury wood‑veneer and fire‑rated double‑leaf door‑sets in hotel, office and public‑building projects. Fully‑hidden frame‑header mounting keeps clean architectural appearance, reliable mechanical sequencing ensures inactive‑leaf closes first to prevent smoke‑leaking gaps, complies with ANSI/BHMA‑156.1‑2000 and EN1935 fire‑safety hardware requirements.
Premium New‑Build Door Projects
Concealed overhead bar‑type design requires frame‑header pre‑processing during new‑construction, not fit for simple retrofit renovation without frame modification. Multiple stainless‑steel grade choices; select SUS316 variant for coastal salt‑air anti‑corrosion conditions. Works well with wooden, metal and swing double‑door‑sets.

Frequently Asked Questions
What makes DR‑003 different from surface‑mount gate‑selector?
DR‑003 adopts concealed overhead bar‑type frame‑header‑integrated design, the whole mechanism is hidden inside door‑header and invisible after installation, focusing on high‑end architectural aesthetics. It requires frame‑header pre‑processing and is not suitable for simple retrofit renovation.
Can DR‑003 be deployed in coastal salty‑air locations?
Standard material is SUS304 stainless‑steel; you may select optional SUS316 variant to satisfy coastal salt‑air anti‑corrosion application requirements.
Does DR‑003 offer custom‑cut bar‑length?
Yes, DR‑003 supports custom‑cut bar‑length within 600‑1800 mm to adapt different double‑door opening‑width for project‑specific requirements.
