We offer a variety of hardware designed to fasten our parking blocks and speed bumps to various types of surfaces and parking lot specifications. Below are different types of hardware for several application surfaces. Lag Bolts Hardware can be used for asphalt and concrete; surfaces where drilling holes is permitted. Zinc Plated Spikes can be used for asphalt only. Anchor Plates can only be used on unsealed, clean concrete and are only available for the Ultra Parking Blocks and/or Speed Bumps. Anchor Plates are mainly used in parking garages. If you have any questions or need help deciding which hardware would work best, feel free to contact us.
