Generally, we recommend 14” mooring spike for installation into asphalt, and our lag bolt hardware set (lag bolt, anchor and washer) for concrete installation. If you have the time and tools to install, using the lag bolt hardware set is the best way to mount/moor the wheel stops at a similar cost to mooring spikes. We also have Eco-Bond adhesive for applications that don’t allow you to breach the surface for installation, such as reinforced concrete or parking decks.
