XMA-01A is a monitor adapter kit that offers you a simple solution to mount the non-VESA monitors. With three adjustable arms, this monitor adapter kit features variety of mounting solutions for different sizes of non-VESA monitors from 17"-27". No need to change the layouts of the previous four arm kit to adjust the structure, each arm can be efficiently adjusted by customized adjustable length. Installing a heavy 4 arms structure is not a good option to remain a clean look for a monitor. The three arms solve the problem by only contacting the central part of a monitor without taking up too much area on the back of a monitors. Although XMA-01A only has three arms, it constructs a stable triangle load-bearing structure. Its load-bearing capacity (8kg/17.6lbs) is as strong as four arms adapter kits. With the lighter and convenient three arms adapter kit, there is no need to worry about those difficulties that the four arms design brings to non-VESA monitors.
