Team 1EV is proud to introduce a new must-have bed accessory for all Rivian R1T trucks. These easy to install ring loop tie downs are engineered specifically to mate to the factory Rivian R1T bed accessory mounting bosses. All Rivian R1T have 16 total mounting bosses in the bed. 4 bosses on each side (3 high, 1 low), and 8 bosses on the front bed wall (4 high, 4 low). Team 1EV offers 4 packs, 8 packs, or 16 packs suited for configuring some, most, or all of the mounting bosses. Our engineers carefully designed the mounting pad so it precisely fits in the Rivian R1T bed liner mounting boss cutout. The bottom side matches the stepped contour of the Rivian bed liner, for precision alignment, sealing, and load transfer. The top side has an industry standard L-Track feature, compatible with any L-Track standard accessory. We include a matching set of single stud L-Track fittings with black anodized aluminum quick disconnect bases and stainless steel round rings. The round ring fittings simply slide and lock into place, and can be quickly removed by pressing the center pin and sliding out of the L-Track. You'll find these patent pending Team 1EV Rivian R1T L-Track fittings to be super convenient in creating the ultimate modular cargo securing and anchoring accessory.
