MORTARNET® ULTRA – ADVANCED MORTAR COLLECTION FOR CLEAR WEEPS AND DRY WALLS
MortarNet® Ultra is a patented, dual-layered mortar collection device designed to keep mortar droppings suspended above the flashing and weeps.

The dual-layer design provides compressibility to accommodate variations in cavity widths, all while maintaining the drainage and ventilation that MortarNet products are known for.
