There are twelve (12) optional Extension Bars of various lengths available individually or in sets (AT-EBZA and AT-EBZB) to screw into the top of an A600 or A700 Aircraft Jack's Slide Tube (or AT500 series jacks equipped with an optional AT500-CA Conversion Adapter). They extend the height of the Jack anywhere from 1.5" to 12.5" (38 to 318mm) in 1" (25mm) increments to provide the optimal lifting height. The top hole of each extender is designed to receive a AT-JPRn Jacking Point Receiver. Additionally, a top-of-the-jack Load Cell can be dropped in place to support aircraft weighing operations.

NOTE: These extension bars cannot be used on the A755C and A760A Aircraft Jacks.
