a collar having an inner surface;
a chassis having an outer surface disposed at least partially within the collar;
a tube or rod at least partially within the chassis; and
at least one clamp configured to fit at least partially around the tube or rod and secured to the chassis, the clamp including at least two bumper pads spaced from one another about the outer surface of the chassis, wherein the at least two bumper pads face the inner surface of the collar and provide points of support between the outer surface of the chassis and the inner surface of the collar to enhance contact and reduce a gap at discrete positions about the outer surface of the chassis;
wherein the downhole tool is deployed in a wellbore or borehole.
