Price is each sheet. last 13 available. Brand new optically clear rigid plastic sheets. Almost certainly Acrylic Coated on one side for chemical, abraision resistance. Measured .230" thick x 54-5/8" x 21-5/16".
The corners are about 2.5" radiused and the edges are machine softened / chamfered or radiused so the edges are not sharp. Ready to set up as a covid shield or use to replace a window or build something. Can be solvent welded / glued / fused on the uncoated side. They have an engraving in one left lower corner. I believe these were intended as replacement windows perhaps for public trains? They have a protective film on both sides. The film removes cleanly and easily. I have other larger plastic sheets available as well. Fewer of those. Also smaller plastic sheets .
