It accepts a 3-wire actuator with an integrated LED status indicator and mounts via a bottom-mount configuration. The damper controls airflow in a single zone by switching between fully open and fully closed positions, making it a straightforward solution for residential and light commercial zoning applications. The 16-inch by 8-inch duct opening size fits standard rectangular duct runs, and the bottom-mount actuator placement suits installations where top or side access is restricted. Licensed HVAC technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis damper is suited for forced-air zoning systems in residential and light commercial buildings where individual zone temperature control is required. It installs inline within a rectangular duct run and is controlled by a zone control board that sends 24-volt signals over the 3-wire connection. The LED indicator provides a quick visual confirmation of actuator position during commissioning and service calls. Typical applications include multi-zone split systems, heat pump systems, and gas furnace installations where a zone control panel manages multiple dampers across the ductwork.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e16-inch by 8-inch rectangular duct opening fits standard rectangular duct sizes\u003c\/li\u003e\n  \u003cli\u003eTwo-position operation  -  fully open or fully closed  -  for straightforward zone control\u003c\/li\u003e\n  \u003cli\u003e3-wire actuator interface compatible with standard zone control boards\u003c\/li\u003e\n  \u003cli\u003eIntegrated LED on the actuator provides visual position status at a glance\u003c\/li\u003e\n  \u003cli\u003eBottom-mount actuator configuration for installations with limited top or side clearance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation zone damper for rectangular duct zoning systems controlled by a 3-wire zone control board.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with local mechanical codes and the zone control manufacturer's wiring diagram. Shut down the air handler and de-energize the zone control panel before installing or replacing the damper. Secure the damper body to the duct using sheet metal screws and seal all joints with UL-listed foil tape or mastic to prevent air leakage. Confirm actuator LED status and full open-to-close travel during system commissioning before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Opening Size\u003c\/strong\u003e: 16 x 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Wiring\u003c\/strong\u003e: 3-wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Position Type\u003c\/strong\u003e: 2-position (open\/close)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Mount\u003c\/strong\u003e: Bottom mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLED Indicator\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Depth\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IO HVAC CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LD-1608-BM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67950029275442,"sku":"LD-1608-BM","price":223.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87434551ce229afb9558d3baad520579_ec4b22e9-fec4-4f75-82c8-9ac59634a318.png?v=1791705679","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-ld-1608-bm-rectangular-zone-damper-16x8","provider":"Voomi Supply","version":"1.0","type":"link"}
