Construction Type CBH is constructed of rugged tubular element with a metal sleeve. Accurate Diameter provides proper clearance into standard drill hole sizes. Large Bolts or Studs may be expanded and tightened with a wrench providing “shrink fit tightness” when cool. CBH Heaters are generally used in sets to permit uniform tightening of mating parts.
