VELUX FCM 3171 Fixed Curb-Mount Skylight — Max Clearance 36 1/8 × 76 1/8

VELUX FCM fixed curb-mount skylights install over a site-built curb and are a strong replacement option for older curb-mounted and acrylic dome skylights.

This current VELUX Skylight System includes the skylight, a pre-installed white room-darkening solar shade, and remote control.

FCM skylights are fixed, non-venting units designed for roof pitches from 0° to 60°.

The standard 2004S configuration uses laminated Low-E safety glass.

Important for FCM 3171: VELUX does not offer a matching factory flashing kit for this size. This skylight installs on a site-built curb. Contact Skylight Specialists before ordering if you need help verifying fit or installation requirements.

Additional glass configurations may be available by size and special order. Contact Skylight Specialists to confirm current VELUX availability before ordering a non-standard glass option.
