| Antelope manufactures the 600
Series Product Line for close tolerance hole size combinations. ..The bow is inset into the end collars
to provide maximum annular clearance. Integral set screws in the bottom collar allow for
pulling centralizer into the hole without the use of stop collars; however, when this is
done, it limits or stops the ability to pull the string from the hole once run. ..These are very popular when running
liners. * US Patent No. 6,679,325 |
