Tried to use this for a 3ft x 6ft framed lid on an enclosed DIY raised bed. It was too strong and the lid not only wouldn't close, but twisted. It was all my fault. I've bought 28lb Suspa racks of the same length and they work great (https://www.amazon.com/gp/customer-reviews/R2JO3VZEVTOQ2B?ref=pf_ov_at_pdctrvw_srp). I decided to keep these 40 lb racks as I might need them for another project one day.
