When installing Parking Curbs to asphalt we recommend using our Rebar Spikes, which are 1/2" in diameter, 14" long with a 1-1/4" flat washer welded to one end and galvanized for a long lasting installation.
When using with Our Parking Curbs remember:
6' Parking Curbs require (4) per curb
4' Parking Curbs require (3) per curb
3' Parking Curbs require (2) per curb
For concrete installation you have a choice of methods; Lag Bolts & Anchors, Wedge anchors, or Adhesive.
