Model 604SB thru 612SB, Clamshells
92-1197 : Rev. 131230
The Adjustable Pads tend to square the Clamshell to the pipe.
If additional precision in squaring is required, consult Tri Tool Inc. about alternate
methods of squaring.
Fine center the Clamshell as you would a 4-jaw check.
Take measurements from the pipe OD to the Housing ID or use a dial indicator to
sweep around the pipe’s outside diameter.
Adjust the Clamping Pads so that the measurements at opposing Clamping Pads
are the same.
