Cleaning out my left over unused Parker boat stuff, I ordered these for my 2017 2820 and had planned to store a life raft in the (unused, clean) rear fish box when I was not on the boat. They should be direct replacements for OEM hardware on late model 2820, 2520, etc. and probably others. Made by Gem, item 5024-1426, Lockable, High quality, Very heavy solid stainless, all hardware, key's etc.. Unused in original packaging, I just opened the shipping box last night. About $140 delivered new, how about $80 via Paypal friends and family delivered CONUS. thank you
