WALI quad monitor stand (model WL-M004) made of high grade steel. Fits most LCD monitors 10" to 27" and supports up to 22 lbs per monitor. Every joint is able to be tightened, so you can adjust exactly how fluid/stationary you want everything to be. Special features include the ability for each individual VESA plate to be level adjusted up and down by 0.8" so your monitors will be perfectly aligned (see pictures). We also made mounting your monitors easy with detachable VESA plates that screw into your monitor and then slide back onto the frame of the stand. An optional bolt through grommet clamp is included with this stand. This has standard VESA 75x75mm and 100x100mm mounting holes.
