{"product_id":"lowell-es-4-rib","title":"Lowell ES-4-RIB Rough-In Bridge For ES-4T Ceiling Speaker","description":"\u003cp\u003eThe Lowell ES-4-RIB is a rough-in bridge engineered for new construction ceiling installations where speaker placement must be committed before drywall is hung. It mounts directly to joists, rafters, trusses, metal rails, or other ceiling support structures, serving as a precise placeholder for the Lowell ES-4T ceiling speaker, which is ordered separately. This approach allows integrators and electrical rough-in crews to lock in speaker locations during the framing phase, eliminating the need for field modifications after drywall is installed.\u003c\/p\u003e\u003cp\u003eFormed from 20-gauge steel with a galvanized finish, the ES-4-RIB delivers a rigid, lightweight mounting point that holds its position through the construction process without adding unnecessary load to the ceiling structure. For AV integrators working on commercial installs, hospitality projects, houses of worship, or corporate environments, this bridge supports a clean, code-friendly rough-in workflow. Priced per unit and ordered in multiples of 10, the ES-4-RIB is well suited for projects requiring coordinated multi-speaker deployments across large ceiling grids.\u003c\/p\u003e","brand":"Lowell Manufacturing Co.","offers":[{"title":"Default Title","offer_id":52446001627320,"sku":"32774","price":25.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/32774_LOWELL-ES-4-RIB_ALT01sqr.jpg?v=1785181502","url":"https:\/\/soundpro.com\/products\/lowell-es-4-rib","provider":"SoundPro","version":"1.0","type":"link"}
