The Euro-Wall Horizon Multi-Slide sliding door system is engineered for greater durability in coastal environments. The system features a flatter sill profile to improve water management, along with hidden anchors, screw covers, and replaceable rollers for easier installation and low maintenance. Slim 1 1⁄2-inch interlocks and a 2 1⁄2-inch center maximize glazing area, while configurations supporting up to eight 72-inch panels, 90-degree corners, pocketing, and reverse stacking help create seamless indoor-outdoor living spaces. The system also features coastal-rated hardware and a powder-coat finish for greater weather resistance.
