Custom quoteWide single-sash gas strut
Infinity Wide-Span Gas-Strut Window
A large upward-opening sash for projects that prioritize an uninterrupted view and service opening.

The clear-opening starting point
A single glazed sash that lifts outward and stays overhead for an unobstructed kitchen or bar opening.
Sash or panels, frame, glass, sill, hardware, controls, freight and installation are verified before a numeric price is released.
Custom product. Final order requires approved dimensions, structure and an accepted order document.
Why it fits
LiftLine organizes the quote around the sash weight, opening width and height, glass, strut force, hinge line, pull location, head clearance, sill and exposure.
Configuration map
Opening, operation, sash or panel layout, glass, sill, frame, finish, screen, controls, freight and installation belong to one record.
Straight answers
Enter the actual rough or finished opening and label the measurement type. The sash or panel layout, frame, glass, sill, hardware, screen, structure and exposure are checked before fabrication dimensions and price are approved.
Two openings with the same area can require different sash weights, struts, panel counts, glass, frames, sills, hardware, crates and freight. Pricing stays quote-based until a verified manufacturing table supports the exact configuration.
Product-only and installation-assisted scopes can be reviewed. Availability depends on the project ZIP, opening condition, waterproofing, structure, access, permit scope and current qualified coverage.
