An infinitely positionable linear friction lock assembly utilizes a single friction spring coaxially disposed about a translating rod within an elongated housing. A bias bushing is provided for slidably supporting the rod. The bushing defines a sloped shoulder against which the friction spring hears, with the angle of the shoulder calibrated to provide an increased holding force up to a predetermined axial force on the rod, and permitting the rod to slip at greater axial forces without disturbing the integrity of the spring or its coils. The assembly includes a release or actuation lever having a cap bushing integrated therein to support the rod and keep the actuation lever in alignment.
