These sidewall mount Bull Ring tie down anchors install just below the GM truck rail and allow you up to 9 tie-down points in the 2007-2019 Silverado, Sierra, Colorado or Canyon truck bed. Rated at 1,000 lbs., the retractable Bull Ring \”Bullet\” fits the same holes as the OEM Chevy GMC tie down anchors, but these retract up and out at a 35° angle when securing loads with ratchet straps or rope. They\’re designed for your truck bed and require no drilling, no special tools, and no hassles. This is a set of 9 single 1001 Bull Rings for 3 holes down each side and 3 across the front. Simply remove the screws, insert the base, lift to the top of the hole, push in the backing plate, center on opening, and re-install the screw. Every Bull Ring comes with a no-bull lifetime warranty.
