- quality and durable construction: This rectangular convex mirror is made with PMMA acrylic and an ABS plastic backing, and can withstand temperatures from -40 F to 257 F. Its sturdy construction is suitable for outdoor use. - pressure resistance: The convex safety mirror resists normal pressure and automatically rebounds without easily damaging the mirror surface. - adjustable angle and bright view: The back is adjustable to provide a wide-angle view that reduces blind spots and improves safety. The acrylic surface is about 20% brighter than glass, offering clearer visibility in dark garages or warehouses. - protective film: A front protective film remains in place during installation to protect the mirror surface; remove the film after installation is complete. - use scenarios: parking driveways or entrances to monitor traffic and backing paths; garage, warehouse, or workshop areas for better visibility in low light; outdoor storefronts or alleyways where wide-angle monitoring enhances safety and security.
