Truth Entrygard Dual Arm Operator Information

The purpose of this page is to help you identify which Truth Entrygard Dual Arm Operator
you should order, in order to ensure everything goes back together properly.  We find many
numbers on these operators, here are just a few of them, 31538, 31539, 30841, 30842,
30472, 30470, 20748, 20755, 20810, or 20544. The number that tells us the most is
the number that starts with a 2xxxx.  This number is the Linkage Arm, that is attached
to the bracket on the hinge side of the window. 

The picture below shows a Linkage Arm, it measures 3-3/4", is offset up and is used
on a Left Hand Operator.
