Thought you guys might like this.
started off with a 1x12x25 peice of PVC board. I took a skillsaw and cut 3/4 in. into the PVC Board every 2 inches except for the ends which I cut 2.5 inches.
Took 100% silicone and siliconed in 8x10 inch sheets of acrylic plexiglass. The plexiglass was bought at my local lowes store.
All done and siliconed in. Will hold up to 12 3700 series plano boxes in my front storage compartment. Every thing is rot free. I will post some more pics after I install it on my boat. Tell me what you think!
