Product Details
Air Louvers VLFIG ThruBolt™ Lead Lined Vision Lites are designed for commercial door applications requiring radiation shielding such as healthcare, laboratory, and imaging environments. Built on the VLFIG ThruBolt™ platform, these vision lites support thicker glazing and non-standard door constructions while incorporating lead sheet lining within the frame.
