ABSTRACT:
An adjustable-position light fixture is provided having a U-shaped mounting bracket and a U-shaped light housing bracket. The light housing bracket is pivotally secured to the mounting bracket via a connection including a key member. The key member has a bearing portion which passes through the light housing bracket and is rotatable in relation thereto. At least one prong extends from the key member and engages a cutout in the mounting bracket to prevent rotation of the key member relative to the mounting bracket. A threaded bolt passes through the key member and is effective to adjust friction between the brackets. The key member is effective to prevent torque on the bolt as the bracket assembly is pivoted so that the bolt maintains the set degree of tension. A head on the bolt is accessible through an opening the light housing so that tension can be readily adjusted with a standard tool.
