The MTM425101 Trellis Mount, part of the most diverse surface mount offerings available, is the most discrete we offer. Our Aurora Mount System (AMS) is built into the unit for maximum aim-ability and 360° fixture rotation. The MTM425101 is machined entirely from solid brass and is just 1 1/2″ in diameter, being the most miniature mount available from Auroralight. Designed for installation onto structures as small as a 2×2” commonly used in many residential trellis applications.
