A typical patio door slides within a pocket sill which creates an area for water and dirt to collect and potentially leak into your home. Our monorail system elevates the sliding panel across a rail which creates a smooth rattle-free glide and a tight seal to lock the elements out.

Many patio door sills are made using aluminum – a material that, over time, is likely to show wear and tear. Our sloped fiberglass sill is more rigid to ensure durability throughout a lifetime of everyday use.

A traditional patio screen door consists of a 2-inch frame and operates along bottom rollers, making it flimsy and vulnerable to obstructions that cause racketing along the track. Our sturdy 3-inch thick frame glides across an unobstructed top-hung track for durability and ease of use.
