DR002 A Stainless Steel Universal Door Coordinator For Double Leaf Doors
DR002 universal mechanical double‑leaf door coordinator manufactured by WINGTEC. Constructed from grade 201 / 304 / 316 stainless‑steel, overall dimension 252x88mm. This surface‑mount mechanical door sequencer ensures correct sequential closing for paired double‑leaf doors, makes the inactive door leaf close prior to active leaf to guarantee proper latch engagement. Anti‑rust, wear‑resistant and long‑term self‑lubricated internal mechanical assembly, keeps stable smooth operation under frequent high‑traffic usage. Simple overhead surface mounting design, full set of installation fasteners included. Compatible with wooden, metal and steel double‑leaf interior‑exterior door assemblies, widely adopted for hospital, school, office and other public building double‑door projects. ISO & SGS quality verified. Monthly production capacity reaches 200,000 units for B2B wholesale commercial institutional building door‑control hardware tender projects.

Application Scenarios
Institutional Public Building Double‑Leaf Door Installations
DR002 stainless‑steel door coordinator is purpose‑built for public‑building paired double‑leaf door assemblies for hospitals, schools and office premises. The mechanical sequencer enforces that inactive door leaf closes ahead of active leaf, eliminating latch jamming and mis‑closure risk on double‑door sets working together with overhead door closers. Non‑handed universal design reduces SKU stock pressure for large‑volume institutional tender projects. ISO & SGS verified quality satisfies commercial building hardware specification requirements.
Multi‑Material Double‑Door New‑Build & Retrofit
DR002 uses premium 201/304/316 stainless‑steel material for excellent rust‑proof and wear‑resistant performance, internal components keep long‑term smooth self‑lubricated operation for heavy‑traffic usage. It fits wooden, metal and steel interior‑exterior double‑leaf doors for new‑construction and existing‑door hardware retrofit replacement assignments. Full mounting fastener kit included for quick overhead surface fitting.
