It thus implies that you can use same extrusion for top and bottom.
Packaging and Shipping: Once the aluminium window profiles have passed all quality control checks, they are packaged for protection during transportation and are shipped to their final destination, where they will be used in window installations.
Step 4 Replace the Rollers (if necessary)

Not the greatest pic, but its tough to find one since the hardware isn’t often shown in detail. These often leave a gap between the rail and post, are tough to get straight, give it a cheaper modular look and draw your eye to them in a not-good way. Counter to that, our Stronghold Iron uses a stronger and cleaner looking cast-iron solid bracket that mounts inline of the fence post.

The thermal break technology does not compromise the strength and integrity of the structure, which means these profiles can withstand harsh weather conditions while requiring minimal maintenance.
