The AGI patented header system is revolutionizing Semi-frameless shower enclosures with its unique wall fix system, polycarbonate construction, and panel holding grippers. Shower enclosures finally have an upgrade! The polycarbonate construction is stronger than aluminum, it doesn’t “oxidize” (leaving the white aluminum oxidation coating), it is sturdier, and thus has no “metallic clang” as the door is opened and closed. Most importantly, it resists bacteria! In a COVID world, this is most important! This system does not require vinyl to hold the panel, which is known to hold and attract bacteria & viruses. The AGI header comes in standard and heavy, with four colors; chrome, brushed nickel, oil rubbed bronze, and matte black. Paired with diamond fusion protection on your glass, Arrow Glass Industries will build you the perfect shower enclosure for a COVID world.
