The plywood is marine brich plywood (not cheap plywood)
It comes with a 1 year warranty.
The vinyl is highest-grade UV-rated vinyl on the market. If you do get a hole in the cover this vinyl will not spread any futher. We also have a company US wide that can fix any hole that you get in the cover.
Yes it is a house hold dead bolt. We are working on a new lock that is more weather proof.
We are also working on a piston upgrade for the cover.
This is not the same one that was on Ebay.
