Do the 2” or the 4” pipe ramps need to be anchored down?

That depends on the application and your requirement. Generally, they do not, just lay down and place your pipe or hose into the open slot. Our 2” pipe ramp weighs 36 pounds and our 4” pipe ramp set (2 ramps that interconnect and bolt together) weigh a total of XX pounds each and are generally stabilized by the newly patented dovetail connector. However, in municipal road uses, they should be screwed or moored in place so not to be dragged out of place. Please take note of vehicle ground clearance and make sure you use signage of a X” ground clearance needed to drive-over these “in-road” pipe and hose ramps. If they need to be anchored in place, we recommend the GRK’s RSS™ Rugged Structural Screw or similar mounting device.
