ABSTRACT:
A reusable fence post for supporting roll-up safety fencing comprising an elongated hollow post having an outside V-angle disposed along a first exterior side of the hollow post; a stake extending downward from a built-in sliding hammer for installing the reusable fence post in the ground without tools; and an elongated jaw member having an inside V-angle hinged at the lower end of the hollow post. The elongated jaw member swings away from the hollow post to receive the plastic fencing and swings toward the hollow post to be latched to the hollow post and held between inside and outside V-angle clamping surfaces, thereby securely clamping the safety fencing to prevent it from slipping either lengthwise or across the width of the fencing. In an alternate embodiment, the outside V-angle serves as the fence post; and the stake, having a cap at its upper end, slides within pipe sections attached to the post.
