Claim 16:
17. A centralizer assembly for use in a wellbore, the centralizer comprising:
a first primary tubular member formed about a centralizer axis, the first primary tubular member having a first end and a second end and a tubular wall extending between the first and second ends, the tubular wall having an inner surface and an outer surface;
three or more first centralizer strip assemblies extending along at least a portion of the first primary tubular member and spaced apart from one another about a circumference of the first primary tubular member, wherein each first centralizer strip assembly of the three or more first centralizer strip assemblies has a first end and a second end, and an outer portion of adjacent the outer surface of the tubular wall and an inner portion adjacent the inner surface of the tubular wall so that the inner portion and outer portion of each first centralizer strip assembly of the three or more centralizer strip assemblies oppose one another forming two seats, one at each of the first end and the second end of each first centralizer strip assembly of the three or more centralizer strip assemblies;
three or more elongated connecting rod assemblies, each elongated connecting rod assembly of the three or more elongated connecting rod assemblies having a first end and a second end and extending an axis parallel with the centralizer axis, where the first end of each elongated connecting rod assembly of the three or more connecting rod assemblies is individually engaged with a first seat of each of the two seats, each first seat of each of the two seats being at the first end of each centralizer strip assembly of the three or more first centralizer strip assemblies;
a second primary tubular member formed about a centralizer axis, the second primary tubular member having a first end and a second end and a tubular wall extending between the first and second ends, the tubular wall having an inner surface and an outer surface; and
three or more second centralizer strip assemblies extending along at least a portion of the second primary tubular member and spaced apart from one another about a circumference of the second primary tubular member, wherein each second centralizer strip assembly of the three or more second centralizer strip assemblies has a first end and a second end, and an outer portion of adjacent the outer surface of the tubular wall and an inner portion adjacent the inner surface of the tubular wall so that the inner portion and outer portion of each second centralizer strip assembly of the three or more second centralizer strip assemblies oppose one another forming two secondary seats, one at each of the first end and the second end of each second centralizer strip assembly of the three or more second centralizer strip assemblies;
wherein the second end of each connecting rod assembly of the three or more connecting rod assemblies is individually engaged with a first secondary seat of each of the two secondary seats, each first secondary seat of each of the two secondary seats being at the first end of each second centralizer strip assembly of the three or more second centralizer strip assemblies.
