The introduction of the Durable Blow Molded Lifetime Outdoor Storage Shed 8 x 10 has rocked the outdoor storage industry, proving once again that innovation, passion, and a drive to make better products can revolutionize an entire market. The Sentinel 6405 Lifetime Shed is similar to the Lifetime Brighton shed and will help you maximize your equipment storage potential. If you find a cheaper price with shipping on the Brighton or Sentinel sheds, let us know and give us a chance to beat the overall price with shipping.

The Bottom Line: The Lifetime Sentinel Shed is ahead of the pack due to its steel reinforcement in the walls and the steel roof trusses. While most competitors use very little metal in their wall construction, the Sentinel plastic sheds have double-wall technology that is unmatched in quality and design.
