This time I am not going to use Duracover on top of the pit. Tired of the issues with this synthetic straw. I am leaning hard at sliding pit tops. 6 in fact on a 16' pit. I don't want to use garage door track and rollers either. Just thinking of keeping it simple with ease of use. Berggren has a neat set up but I can't for the life of me figure it out. In my mind I visualize a wood lid with some sort of guide to keep it straight when slid back. Maybe 1/2" or 3/8" plywood lid, nothing heavy. The lids will be 24" long x 32" wide. I need some more ideas on a track to slide the lids on/in. Maybe uni-strut track...dunno. What do you guys have in mind? Can you help me out here? Thanks in advance, Murph.
