Good To Know

Q: Can this be used with 6x6 posts? A: No, this spike is designed specifically for 4x4 dimensional lumber; using it with larger posts will not provide a secure fit.

Q: Do I need to set the spike before or after the concrete cures? A: Insert the spike into the wet concrete and position the post before the concrete sets to ensure proper alignment and hold.

Slight variation in finish or dimensions may occur between production runs, and serial number, so confirm compatibility before ordering.
