Aluminum T-Slot Profile Framing Technology
Aluminum T-Slot Framing Corner, Curved - Angle Profiles 20mm, 30mm, 40mm, and 80mm

Often times when designing a structure it can be desirable to incorporate curve profiles, curved/radius corners, or flat edge corner into the design and while still having the T-Slot functionality where needed. Paletti offers curved/radius profiles, curved/radius corners, flat edge style corner, and angled profiles.

Please note – there are no End Caps specifically designed for the Angle Profiles. However, a combination of our straight 40mm End Caps can be used to sufficiently cover the ends of the angle profiles.
Information about those end caps can be found near the bottom of our 40mm profile page using this link: https://palettiusa.com/aluminum-framing/40mm
