Molded rectangle; single HEAVY piece, weighs over 5Lbs!

Exact exterior dimensions: 23.375" x 13.375" x 1.75" deep

Beautiful, deep Navy blue marbled lid rests but DOES NOT lock down on the topside of spa (underneath would lie twin filters, permitting the skimmer flow to pull spa water from the surface down through the filters and plumbing)

This component was standard for most Sundance Spas models during the the early to mid-90s (was recently removed from a 1995 model)
