Dimensions of the T-Bolt Included with the Replacement Adapter # 8880637


Hi, Im wondering what the measurements are for the flat metal section of the bar adapter. I have a pair of old bars with a t-slot and would like to use them with my timberline towers. I want to make sure the adapter will fit into the .44 inch opening.

The flat part of the t-bolt with the Replacement Adapter and Seat for Yakima JetStream Crossbars # 8880637 measures 3/4" x 1-3/16" as demonstrated in the attached photo.

This adapter is compatible with your TimberLine towers, but was made by Yakima specifically for their JetStream crossbars. If you let me know the length of the crossbar that you need and which color (Black or Silver) you would like I can recommend the appropriate JetStream crossbars for you.
