How to Measure

  • Width: Measure the opening at the top, middle, and bottom. Use the smallest of the three measurements.
  • Alignment: Use a level to make sure the sides are straight and plumb.
  • Height: Measure at the center of the arch — or the highest point of the opening if it’s square.

Note: For rough openings, we recommend adding 0.5" to both the width and height to allow for finishing and easy installation.

Frequently Asked Questions

Our doors feature a carbon steel frame with tempered glass panels, ensuring durability and style. The steel is finished with a matte black powder coating for a sleek, modern look.

  • Steel Thickness: 1.26 inches (32 mm)
  • Glass Thickness: 0.20 inches (5 mm)
  • Frame Width/Thickness: 1.57 inches (40 mm)
  • Weight (Without Packaging): 85–100 lbs, depending on size and style

Tempered glass is heat-treated to be stronger and safer than regular glass. It's designed to shatter into small, less harmful pieces in case of breakage.

Carbon steel is a durable, high-strength material that's resistant to wear and corrosion, making it ideal for long-lasting doors.

  • Clear Glass: Maximizes light and openness for modern spaces.
  • Frosted Glass: Enhances privacy with a soft, diffused glow.
  • Gray Glass: Offers a sleek, tinted look for added elegance.
  • Ribbed Horizontal Glass: Provides texture and privacy with a linear design.
  • Ribbed Vertical Glass: Adds dimension with striking vertical patterns.

Note: Glass type does not affect the price.

Our doors come pre-hung in a steel frame. Add a 0.5-inch gap to both the width and height for proper adjustments during installation. For example, a 36" x 96" door requires a rough opening of 36.5" x 96.5".

  • Use a level to check alignment and note any adjustments needed.
