Construction, insulation, sizing and warranty details for every Garage Door Lift product line. R-values and cycle ratings are source-listed values, not a stated whole-door thermal rating. Unconfirmed glazing, grille infill, wind-load ratings and certifications are intentionally omitted until verified.
R-value and spring cycle are source-listed values. Test method and whole-door thermal performance are not provided. Final hardware and spring selection must suit the ordered door configuration.
The 2600 range is separate from the 6000 aluminum overlay and 7000 insulated overlay families. Final sizes, design options, colors, glazing and hardware must be confirmed with the order.
These 12 size combinations describe the standard insulated steel offering. Availability varies by model, size, color and current stock. This chart does not establish standard sizes for specialty models. Other dimensions may be available by custom order, subject to manufacturing limitations and order confirmation.
Listed insulated-steel family options include black, white, grey, brown, oak, walnut, almond, beige, and custom colors. Confirm the selected model, finish, color sample and availability before ordering.
The insulated-steel family lists plastic-framed windows with double tempered glass, in clear, black-tinted or frosted options. Custom window options are available, including horizontal rows, vertical stacks, square and rectangular windows, and custom angled shapes or layouts. Window shape, size, quantity, placement and glazing are subject to the selected model, panel dimensions, structural requirements and manufacturing approval. Submit your preferred design or reference photo for confirmation before ordering.
GL3500 and GL3520 are both non-insulated - no foam-core insulation or R-value is advertised. Frame dimensions, profile thickness, glass build-up, hardware and size limits will be added after the model-specific technical assignments are confirmed.
Aluminum grille (6120): standard and custom sizes are available, subject to configuration confirmation. Installation is available. Grille infill material and performance ratings are omitted pending verification.
Glazing details are omitted pending verification. The 6000 family is not the 2600 insulated steel-back range.
R-17.5 applies to the separate 2-inch 2600 steel-back range, not to the 7000 overlay products. Exact design and thickness must be confirmed with the ordered configuration.
Production and delivery times may vary and could extend beyond these estimates due to manufacturing, shipping, customization or unforeseen delays. Final availability and estimated delivery timing should be confirmed when the order is placed. All lead times are estimates, not guaranteed delivery dates.
Before placing an order, confirm model, finished opening dimensions, design, color or finish, glazing, track arrangement, hardware, installation requirements, current availability, and estimated delivery timing in the written order.
