Excellent, but concerns over expansion/contraction
Construction is top quality, heavy duty. These speed bumps will stand out in both day and night with its bright yellow stripes and inset reflectors. Since I received mine in December I haven’t mounted it yet due to concerns about expansion/contraction as the months go from cold to hot and back. I don’t want it to buckle when the asphalt pavement is at its hottest. I’ll mount it when the weather is in the 70’s.
I found it odd that one of the holes for the coupling rods was square rather than round, but the end with the square hole will go to one end where no rods are used to mate with an end piece.
