ASI 0600-2420 Inter-Lok Angle Frame Mirror, 24" W x 20" H
This surface-mounted plate glass mirror has a 3/4" x 5/8" roll-formed, 18-gauge Type 304 stainless steel interlocking angle frame. Its heliarc-welded corners are ground and polished smooth to a uniform satin finish. A concealed hanging bracket locks to the top and bottom of the frame with tamper-proof set screws, and a theft-resistant locking device secures the one-piece back plate.
Install the bracket level and plumb using #10 self-threading screws (by others). Hang the mirror on the bracket and tighten the locking screws at the top and bottom. ASI's installation guidance for the standards it cites places the bottom edge of the reflecting surface no higher than 40" above the finished floor.
