It accepts a 3-wire actuator with an integrated LED indicator, allowing technicians to confirm damper position at a glance during commissioning or troubleshooting. The bottom-mount configuration positions the actuator beneath the duct blade for installations where top or side access is limited. At 9 pounds, this is a robust assembly suited for commercial and residential zoning applications where reliable airflow control is required on larger duct openings.\u003c\/p\u003e\u003cp\u003eThis damper is sized for 18-inch by 10-inch rectangular duct applications. It fits into zoning systems that require two-position control  -  fully open or fully closed  -  making it appropriate for multi-zone residential systems, light commercial VAV-style applications, and new construction or retrofit duct layouts. The bottom-mount actuator design is commonly specified when overhead clearance is tight or when control wiring is routed from below the ductwork. HVAC technicians and sheet metal contractors are the primary installers for this type of zone damper assembly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTwo-position operation provides fully open or fully closed airflow control\u003c\/li\u003e\n\u003cli\u003e3-wire actuator allows direct integration with standard zone control boards\u003c\/li\u003e\n\u003cli\u003eIntegrated LED indicator confirms damper position without removing covers\u003c\/li\u003e\n\u003cli\u003eBottom-mount actuator suits installs with limited top or side duct clearance\u003c\/li\u003e\n\u003cli\u003e18-inch by 10-inch rectangular duct sizing fits larger supply or return trunk branches\u003c\/li\u003e\n\u003cli\u003eSturdy construction at 9 pounds supports long-term mechanical reliability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation zone damper for rectangular duct zoning systems requiring two-position, 3-wire actuator control in 18-inch by 10-inch duct openings.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal contractor familiar with zoning system wiring and duct modification. Shut down the air handler and de-energize the zone control panel before connecting or disconnecting actuator wiring. Verify that the zone control board is compatible with 3-wire actuator configurations before completing wiring connections. Follow local mechanical and electrical codes, including applicable sections of the IMC and NEC, when mounting the damper and routing low-voltage control wiring.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Opening Size\u003c\/strong\u003e: 18 inches x 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: 3-wire with LED indicator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation\u003c\/strong\u003e: 2 position (open\/closed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Style\u003c\/strong\u003e: Bottom mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 22 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-1810-BM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67950378320178,"sku":"LD-1810-BM","price":241.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87434551ce229afb9558d3baad520579_9e3c7cdc-f6ad-4e36-bda2-9ac074c51f83.png?v=1791715794","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-ld-1810-bm-zone-damper-18x10-bottom-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
