  • Excellent quality
Color: Black Style: Angled Pair Sealed
This company seems to build quality enclosures. These are no exception. Well built and exactly what I was looking for. I did have to purchase some poly for these. The other selections appear to include the poly but not these. Shipping package was secure as well.
