{"product_id":"oem-bumper-grille-screen-metal-lh-freightliner-cascadia-obstacle-sensor-21-28972-001","title":"OEM Bumper Grille Screen Metal LH - Freightliner Cascadia Obstacle Sensor - 21-28972-001","description":"\u003cp\u003eKeep the Cascadia's forward collision-avoidance system seeing the road with this genuine \u003cstrong\u003eFreightliner OEM bumper grille screen\u003c\/strong\u003e, left hand. It drops into the left side of the front bumper center opening and shields the forward obstacle detection sensor from rocks, road debris and bug buildup — the exact junk that blankets a sensor face and starts throwing false collision-avoidance warnings and radar faults. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, truck body shops, and owner-operators nationwide.\u003c\/p\u003e\n\n\u003ch2\u003eClear Sensor, Quiet Dash: The OEM Bumper Grille Screen Advantage\u003c\/h2\u003e\n\n\u003cp\u003eThis is the factory screen, not a universal mesh panel cut down to fit. It is built from \u003cstrong\u003emetal\u003c\/strong\u003e and finished in \u003cstrong\u003eVolcano Gray\u003c\/strong\u003e with a plain finish, so a repaired bumper matches the rest of the front end instead of reading as a patch. Because the contour is the OEM contour, the screen seats correctly in the bumper center opening and leaves the sensor sitting exactly where Freightliner put it — which is the whole point of replacing a broken screen instead of running the opening empty.\u003c\/p\u003e\n\n\u003cp\u003eA sensor that is packed with bugs or blasted by gravel is a sensor that reports faults, and a truck that throws collision-avoidance warnings on a clear afternoon burns driver confidence fast. This is the \u003cstrong\u003eleft-hand\u003c\/strong\u003e half of the pair; it installs together with the right-hand screen, \u003cstrong\u003e21-28972-002\u003c\/strong\u003e, and the two of them fully close the bumper center opening. Order this one on its own when a road strike took out the left screen, or both when the opening is wide open. It is a direct replacement for the highly searched Freightliner number \u003cstrong\u003e21-28972-001\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eVehicle Fitment \u0026amp; Compatibility\u003c\/h3\u003e\n\u003cp\u003eThis genuine Freightliner screen is intended for the following commercial application:\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMake\/Model:\u003c\/strong\u003e Freightliner New Cascadia (P4), 2018 to 2025\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRequirement:\u003c\/strong\u003e Trucks equipped with a front obstacle detection sensor in the bumper\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePosition:\u003c\/strong\u003e Left-hand side of the bumper center opening\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eComponent Group:\u003c\/strong\u003e Front Bumper \/ Sensor Protection Screens\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eDirect Replacement \u0026amp; Cross-Reference Numbers:\u003c\/h3\u003e\n\u003cp\u003e\u003cem\u003eThis genuine screen serves as a direct replacement for the following part number:\u003c\/em\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFreightliner Interchange:\u003c\/strong\u003e 21-28972-001\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Bumper Grille Screen, Left Hand\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Metal\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Volcano Gray\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Plain\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Covers the left side of the bumper center opening and protects the obstacle detection sensor\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePairs With:\u003c\/strong\u003e 21-28972-002 (right-hand screen)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Freightliner (Distributed by FleetPro Parts \u0026amp; Tires)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Freightliner","offers":[{"title":"Default Title","offer_id":43036192735303,"sku":"21-28972-001","price":22.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/8035\/2583\/files\/image_1920_a4fc23f6-bc11-44d1-ad44-c9e521436c92.webp?v=1787697274","url":"https:\/\/fleetpropt.com\/products\/oem-bumper-grille-screen-metal-lh-freightliner-cascadia-obstacle-sensor-21-28972-001","provider":"FLEETPRO PARTS \u0026 TIRES","version":"1.0","type":"link"}
