The cable spacing is engineered to prevent children from slipping through or climbing, and the high tensile strength ensures the barrier cannot be pushed open or broken. Unlike wide-bar traditional grills, children cannot get fingers or limbs trapped between the cables.
Traditional iron grills are bulky, block natural light and views, require regular painting to prevent rust, and look visually heavy. Invisible grills use thin stainless steel cables that are nearly transparent, never rust, need no painting, allow full air circulation and unobstructed views, and give your home a modern, premium look — at comparable or lower long-term cost.

Invisible grills are extremely low maintenance. Simply wipe the cables and channels with a damp cloth and mild soap every few weeks to remove dust or grime. Never use harsh chemicals, bleach, or abrasive cleaners as these can damage the cable coating. Since the cables are rust-proof and weather-resistant, no painting, oiling, or re-coating is ever required.
