Engineering Excellence

Value-engineered vinyl windows with uncompromised strength

The 1733 Window Series combines structural rigidity with economical profile geometry. Designed for multi-family developments, housing projects, and commercial retrofits, this platform features bevelled multi-chamber extrusions, steel-reinforced sashes, and high-performance energy efficiency—manufactured factory-direct in Southern California.

Reinforced Sashes

Internal steel and aluminum reinforcements provide structural stability against wind loads and frame distortion across large operational openings.

Autolock Hardware

Heavy-duty positive cam autolocks provide seamless operational security and audible confirmation upon closing moving sashes.

LoĒ³-366 & Argon

3/4" dual-pane insulating glass with Duralite warm-edge spacer and argon gas fill dramatically cuts HVAC thermal loads.

Dual Frame Profiles

Available in 3-1/4" retrofit frame depth for quick replacement or 2-3/4" nail-on frame depth with standard or wide fins for new construction.

Component Highlights

Precision hardware and weatherproofing details

Every 1733 Series unit is built using premium hardware and high-density weather seals to deliver smooth operational performance over decades.

Autolock mechanism on 1733 Vinyl Window Series

Heavy-Duty Autolock

Integrated automatic locking latch ensures high security and effortless operation every time the sash is pushed closed.

Integral Pull Rail

Full-length continuous pull rail extruded directly into the sash profile eliminates add-on handles and prevents hardware failure.

B2B Buyer FAQ

Frequently Asked Questions on 1733 Series

Essential details for general contractors, property developers, and international importers.

Yes. The 1733 Window Series is designed specifically for apartment retrofits, housing authority projects, and commercial developments. Its 3-1/4" retrofit flush fin frame makes installation over existing window frames fast and weather-tight without disturbing interior trim.

Structural steel and aluminum inserts are placed inside the vinyl sash chambers. This prevents vinyl bowing, enhances wind load resistance, ensures smooth sliding operation under high thermal variation, and securely anchors the locking hardware.

While the interior remains clean white virgin vinyl, we offer high-grade exterior architectural laminates in Black, Dark Bronze, and Anodized Silver. These laminates resist peeling, chalking, and heat absorption even in intense sunlight.

Every order is produced to exact 1/8-inch tolerances. Units are individual-barcoded with opening numbers, fitted with corner guards, heavy-duty shrink wrapped, and palletized into export crates to guarantee damage-free container transport and seamless job site distribution.
