All Mnpctech Non-Reference GPU Support brackets measure 12-3/4" long by 1.5" wide.
This support bracket is designed for single Non-Reference Cooler GPU systems only. It will not work with Crossfire or SLI setups. Won't fit between two or more video cards. Our single 980 Ti GPU support bracket will be designed for single GPU systems only. We don't recommend using our single GPU support for Crossfire/SLI. The bracket is too wide to accommodate all Crossfire/SLI equipped systems. There is manufacturer shroud designs that will obstruct the bracket from mounting correctly in Crossfire/SLI setup. There is also risk of crossing solder points and shorting out GPU mounted below the bracket. A backplate can prevent crossing solder points, but not all graphics cards have back plates. This is why we don't endorse or recommend consumers using our single support in any Crossfire/SLI setup.
