A set of twelve (12) Extension Bars in 6 lengths ranging from 2.5" to 11.5" in 1.5" increments. They screw into the top of A600 or A700 Aircraft Jack's Slide Tubes (or AT500 series jacks equipped with an optional AT500-CA Conversion Adapter) to provide the optimal lifting height. The top hole 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.
