A set of two-The package consists of two monitor brackets with a length of 15.3'. If the monitor is small, you can use them separately, or you can connect them into a monitor bracket with a length of 30.6' to hold your oversized monitor. Firm structure-This design uses the friction between the C-clamp and the desktop to offset the gravity of the computer monitor. Save space-Due to the special structure of the C-clamp, there is an open space under the bracket with a height of 4.3'. Easy to install-We provide all the necessary hardware and instructions to facilitate the assembly. After-sales service- Free replacement of vulnerable parts such as C-clamps within three years of purchasing this product.
