Follow the measurements and you will get what you ordered. The only downside is that the coating is peeling off. I used them to reinforce a flimsy railing to keep my toy Aussie near our home in rural Wyoming. I removed the cover in colder weather which made my fingers suffer from the cold. I didn't know how much I might need so I took off half before going outside. Fewer coating cracks when exposed to heat, i.e. before installation, not after. No rusting after months of rain, snow and freezing fog.
