These clear step covers are made by another small Minnesota company. They are similar to the Safe Step Covers we manufacture, but are constucted of a water clear polycarbonate material. When stood on, they flex more than our Safe Step Cover, but the material is very strong and some anglers will appreciate the transparent material for watching their bobbers in the hole. They will do a great job of keeping your valuables from making it down the hole! You must specify whether you use hole sleeves or not for the proper fit.
