About Syneticusa
SYNETICUSA designs retractable hard tonneau covers, truck bed rack systems, LED lighting, and outdoor gear for pickup trucks, operating out of a head office and warehouse in Santa Fe Springs, California. The company's cover lineup spans four operation types under one platform -- the MB manual rolling series, the MR manual PRO with T-slot rails for mounting racks, the AR automatic retractable with a switch-knob motor, and the ER fully powered electric cover with remote control and integrated LED bed lighting -- built from 6063-T5 aluminum slats with a powder-coated finish and rubber-sealed rails with a water drainage system.
On RevRated, the Syneticusa MB Series is the upgrade pick in our tonneau cover roundup, standing out for delivering the retract-into-a-canister functionality and dual-key multi-position locking of premium retractable brands at a meaningfully lower price than established retractable competitors like Retrax. SYNETICUSA has also expanded from tonneau covers into rooftop tents through its RoofNest line, reflecting a broader push into truck-based outdoor gear beyond its original bed-cover business.

Syneticusa MB Series Retractable Tonneau Cover
Aircraft-grade 6063-T5 aluminum slats with a powder-coated matte finish deliver the retract-into-a-canister function of premium retractable covers at a price well under established competitors like Retrax. The dual-key double-lock system secures the cover at the canister and at any retracted position along the bed, letting owners lock in a partially open state to screen tall cargo while still securing the rest of the bed -- a multi-position feature most retractable covers under 1,000 dollars do not offer. A 600-pound evenly distributed load capacity is the highest in our roundup, and the cover carries a 3-year manufacturer warranty with a video-supported DIY install.
