This cover was exactly what I needed to finalize my DIY build. It is well insulated and I am very impressed with the quality. This cover fit my 100 gal stock tub perfect. It also came with clips that have locks integrated with keys.
We live in Texas and get a lot of wind. I had built my own lid which was heavy but didn't blow off. So, the tie downs are an excellent addition that should work great. My only thought for improvement would be to cover it with a heavy duty silver vinyl rather than heavy black vinyl. We get a lot of sun and heat. A light reflective color would be more effective at helping it stay cool and might not get eaten up by the sun as quickly as I suspect the black vinyl will. It is a great product!
Arrived fast, well made. Don't hesitate to order.
