Justrite GNRS914000 14 in Rebar Spike - Each

These 14 in steel spikes are designed for mounting parking curbs and speed bumps and humps into asphalt surfaces. To install, simply drill a hole into the asphalt and hammer the spike through the parking stop until it is snug against the surface. If the asphalt is older, you may want to coat the spikes with epoxy to prevent it from cracking. Not for use with concrete surfaces.
