DR‑001B 9‑Inch Stainless Steel Gravity Door Selector For Hollow‑Metal Double‑Door
DR‑001B heavy‑duty 9‑inch gravity door selector from WINGTEC. Constructed of casting SUS304 stainless‑steel body and arm fitted with wear‑resistant nylon roller. Fixed 9‑Inch (200*225 mm) projection dimension, overhead soffit surface‑mount installation. Gravity‑powered mechanical sequencing prevents active leaf from closing before inactive leaf is fully closed, avoiding door‑strike, mis‑latching and sealing gaps for hollow‑metal paired double‑door‑sets. Gravity action arm and door bracket support on‑site adjustment for installation alignment. Passed 200,000‑cycle durability test for door mass up to 120 kg, complies with ANSI/BHMA‑156.1‑2000 and EN1935:2002 standards. Fully non‑handed reversible for left‑right double‑door layouts. Works cooperatively with standard surface‑mount door closers. Suitable for hollow‑metal, wooden, steel and fire‑rated double‑leaf door assemblies. Full‑set installation mounting hardware included. Monthly production capacity reaches 100,000 units for B2B wholesale architectural hollow‑metal double‑door hardware tender projects.

Application Scenarios
Hollow‑Metal Double‑Door Public‑Building Installations
DR‑001B 9‑inch gravity door selector is purpose‑built for hollow‑metal double‑leaf door‑sets in hospital, school, office and public‑building projects. Gravity‑driven sequencing guarantees inactive‑leaf closes first to avoid door‑impact and mis‑latching. Adjustable arm‑bracket simplifies field alignment work. Complies with ANSI/BHMA‑156.1‑2000 and EN1935 hardware standards for commercial hollow‑metal double‑door safety assemblies.
New‑Build & Retrofit Hollow‑Metal Door Projects
Overhead soffit surface‑mount design adapts both new‑construction and renovation retrofit without heavy frame modification. Cast SUS304 stainless‑steel delivers reliable anti‑rust performance for indoor and mild outdoor environments. Optimized 9‑inch projection dimension fits larger hollow‑metal double‑door opening widths.
