Arm apparatus with reinforcement

摘要

An extension arm apparatus is provided for mounting devices such as flat panel monitors above a workspace. The apparatus includes upper and lower channels connected to a pair of endcaps. One endcap may connect to the workspace and the other endcap may connect to an extension arm or to the device to be mounted. At least one of the channels includes a reinforcement structure providing additional support to the apparatus. The reinforcement structure is tapered. A forearm extension may also include a reinforcement structure. The endcaps may have interior spacers that provide clearance for the sidewalls of the channels, which may be fabricated without parting lines.
