CRL Black Bronze Anodized Wide U-Channel Top-Load Gasket 3/4in 20ft

• SKU: NH3DU240 — Aluminum extrusion that matches the width of door and sidelite rails for 3/8" or 1/2" (10 or 12 mm) and 5/8" or 3/4" (16 or 19 mm) glass
• Accepts roll-in glazing gasket, top pivot block, and snap-in filler strip for secure glass installation
• Ready-to-ship models from CRL inventory; available in stock lengths, fabricated headers, or headers with side pockets for 'lift and drop' panel installation

This aluminum extrusion was developed for three primary uses:

1. As a U-channel that matches the width of CRL sidelite and door rails for a clean perimeter finish.
2. As a narrow header—same width as sidelite and door rails—that accepts a top free-swinging pivot to secure the top of doors.
3. As an even sight line system: install the 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 visual alignment.

All drilling, tapping, and fabrication can be performed during manufacturing to save installation time.
