This aluminum extrusion (SKU: NH3SASL) was developed for three primary applications:

1. U-Channel that matches the width of CRL sidelite rails and door rails—ideal as an aluminum U-channel for glass doors and sidelites.
2. Narrow Header, same width as CRL sidelite and door rails, capable of accepting a top free-swinging pivot for secure door installation.
3. Even Sight Line System: install a fabricated narrow header at the top of the opening, then secure the sidelite rail to the header using the 1/4" (6 mm) header saddle for a consistent sight line across the assembly.

All drilling, tapping, and fabrication can be completed at manufacturing on request to save installation time. This extrusion is particularly suited for storefront and interior glass door systems requiring precise sight lines and compatibility with roll-in glazing gaskets and top pivot hardware.

Quick Pick policy: stocked centrally and shipped to regional CRL service centers on weekly re-supply trucks. If your regional center is out of stock, orders are typically filled within a few days. Check local availability by clicking "CHECK STOCK AVAILABILITY" above.
