This auction is for 2 fiber optic splice trays

Each tray has its own lid 

you can splice 1-24 fibers inside this tray

I personally would suggest only 12 if tight buffer tube 

if OSP loose tube maybe 24 splices would be ok

You can remove the lower splice tray lid and lock the upper splice tray to the lower tray

If you do this the trays, will stay/lock together and hinge open.

  The upper installed tray bottoms will be the lower tray lid.
