Reliable product. Installed on 4runner 2012. The screen size is 1.5 inches as advertised. The installation went smoothly. The nuts supplied are flush with the studs. Solid attachment. I used red Loctite and tightened to 100 ft/lbs. Now he's in front, that's scary crap. See image. The supplied nuts are too short compared to standard cleats. I was too scared of losing a wheel on the freeway. I had to purchase extended threaded locknuts to replace the ones that came with the kit to give me peace of mind that metal is being held back. Be sure when installing. Use a torque wrench and Loctite
