NGP L-VGLF-WD Security Door Window Lite — 1/2" Lexan Polycarbonate, Wood Door

The National Guard Products L-VGLF-WD is a heavy-duty security door window lite engineered for wood doors requiring a tamper-resistant, high-impact vision panel. Built with 1/2" thick Lexan polycarbonate glazing set in an 18-gauge cold-rolled steel frame, this unit delivers outstanding impact resistance where standard glass would fail — making it a dependable choice for schools, correctional facilities, healthcare corridors, industrial plants, and any application demanding a vandal-resistant door lite.

The low-profile frame and concealed fastener design keep the exterior face clean and tamper-resistant, while mitered and welded corners provide structural rigidity. Silicone sealant is included for a weathertight, rattle-free installation. Standard finish ships in gray primer (GPZ), ready for field painting to match door color.
