Thanks to HMEs T-Post Trail Camera Holder, its now a breeze to attach your trail cam to any side of most traditional T-style fence posts. Simply loosen the treaded knob enough to slide the holder over and around the post and tighten to ensure a secure mount. Once installed, your trail cam can be rotated to and held in the desired position. Cancer and Reproductive Harm- www.P65Warnings.ca.gov. Type: Grips.
