SHIELDS makes both in 1\/2 inch polycarbonate shaped like the originals, duplicates the mounting holes and coats both sides with SUPERCOAT. You can buy each window on its own, in clear or tint. The 308E CR and 308E2 CR also use a different set, so check your glass number first.\u003c\/p\u003e\u003cp\u003eSHIELDS 1\/2 inch polycarbonate windows replace the flat front upper and lower glass on the CAT excavators SHIELDS groups as its 308 to 315 set.
