BAK Industries BAKFlip MX4 TS Hard Folding Tonneau Cover with T-Slot Rails for 2015-2020 Ford F-150 (6.5ft Standard Bed)
The BAKFlip MX4 TS 449327TS Hard Folding Tonneau Cover combines heavy-duty cargo security with integrated T-slot side rails for ultimate cargo management on 2015–2020 Ford F-150 trucks equipped with a 6.5-foot standard bed (6' 6" / 78" bed box).
Engineered with heavy-duty aluminum top panels over precision-engineered side rails, this cover supports over 400 lbs. of evenly distributed payload. Built-in T-slot channels allow seamless installation of top-tier truck bed racks, crossbars, and gear carriers directly above the bed without sacrificing cover functionality. Finished in an advanced UV- and scratch-resistant automotive coating, the MX4 TS resists impacts, dents, and extreme weather.
Bed protection specialists highlight that the MX4 TS provides 100% full bed access by folding upright against the cab while keeping the third brake light completely visible.
