A basic clamping cradle for an elongated tubularly cased TV or photo strip camera, used in pipe survey or inspection and similar operations, has a pair of like elongated bottom runners each connected to a respective longitudinal frame element at front and back ends through a pivotally extensible linkage having variable points of shiftable attachment, whereby the runner spacing may be adjusted to support a camera substantially at the axis of pipes of different sizes within its range.
