Product Description
This is a lighter weight version of the 4 piece set here: https://shpws.me/TD8m. Still super sturdy. The added hole makes it easier to handle.
Copied from the original:
Four accessory port adapter pieces, 2 regular, 2 offset (A and B), which can be used to mount a single DIY crossbar. These fit 2 ports.
Tested for compatibility with Rivian R1T (2022). Threaded holes for M10 bolts. Should be used with a bracket such as the "2-Hole Flat Straight Strut Fitting Bracket" sold at hardware stores. With four of these (plus 4 M10 or 3/8th bolts, nuts, and 2 brackets), you can mount strut across the ports of the truck bed to fashion DIY crossbars for well below OEM crossbar prices.
Note: this is for the truck bed accessory ports only. The rooftop ports take a different adapter.
