Auralex MAX-Wall Corner Coupler

MAX-Wall panels interlock in a straight run by default, and the Corner Coupler is what lets that run turn a corner instead of stopping at one. The kit is twelve 20 in coupler pieces, enough to join a full MAX-Wall setup around an angled or cornered wall rather than treating each wall as a separate, disconnected run.

It matches the Studiofoam finish of the rest of the MAX-Wall line and ships in the same three colors, so a corner join reads as part of the same system instead of a visible seam.
