DR002B Stainless‑Steel Universal Double‑Leaf Door Coordinator Device
DR002B overhead‑mount universal mechanical double‑leaf door coordinator manufactured by WINGTEC. Constructed from select SUS201 / SUS304 / SUS316 stainless‑steel, overall dimension 280x90mm. This surface‑mount mechanical door sequencer controls closing sequence for paired double‑leaf door assemblies, ensuring the inactive leaf closes before the active leaf for reliable latch engagement. Wear‑resistant nylon roller wheel plus long‑term self‑lubricated internal mechanical assembly delivers smooth operation under frequent heavy‑traffic cycles. Compliant with BS‑EN, CE, UL, ANSI, BHMA, ISO and SGS verification standards. Simple overhead surface installation with complete mounting fastener kit included. Compatible with wooden, metal, steel and fire‑rated interior‑exterior double‑leaf door sets, widely deployed in hospitals, schools, offices and multi‑purpose public institutional building projects. Monthly production capacity reaches 200,000 units for B2B wholesale commercial‑institutional door‑control hardware tender projects.

Application Scenarios
Institutional Public‑Building Double‑Leaf Door Installations
DR002B stainless‑steel door coordinator is purpose‑built for hospital, school and office public‑building paired double‑leaf door assemblies. Gravity‑driven mechanical sequencer guarantees the inactive door leaf closes before active leaf, eliminating latch jamming and mis‑closure risk when used together with overhead fire‑rated door closers. Non‑handed universal design lowers inventory SKU burden for large‑volume institutional tender projects. Product meets BS‑EN, CE, UL, ANSI, BHMA, ISO and SGS standards for global commercial building hardware specifications.
Multi‑Material Double‑Door New‑Build & Retrofit
DR002B offers grade‑selectable 201 / 304 / 316 stainless‑steel for different anti‑corrosion requirements; 316 grade suits coastal high‑salt‑air environments. Nylon roller plus self‑lubricated internals sustain smooth performance under heavy‑traffic usage. Works for wooden, metal, steel and fire‑rated interior‑exterior double‑leaf doors for new‑construction and existing‑hardware retrofit assignments. Full mounting fastener kit supplied for quick overhead surface fitting.
Architectural Hardware Tender Specification Projects

Frequently Asked Questions
What application is DR002B door coordinator for?
DR002B mechanical overhead door coordinator is designed for paired double‑leaf door assemblies in hospitals, schools, offices and public‑institutional buildings. It controls closing sequence to ensure inactive leaf closes prior to active leaf, preventing latch‑failure issues, works together with overhead hydraulic door closers.
How to choose stainless‑steel grade for DR002B?
SUS201: cost‑effective for indoor dry‑environment projects; SUS304: general‑purpose for interior‑exterior normal conditions; SUS316: recommended for coastal, salt‑spray high‑corrosion‑risk environments.
Does DR002B require power supply or wiring?
No. DR002B is pure gravity‑mechanical door sequencer without any electronic parts. It relies on mechanical structure, no power cable is needed for installation and operation.
