This is a used pair of Teeter 'traction' handles - they help manually add decompression to any Teeter inversion table for a deeper stretch. Minor abrasion highlighted in on of the photos.

THREE-IN-ONE SOLUTION
Add Decompression – Gently push on the handles to add traction to achieve a deeper stretch for people who prefer a lesser angle of inversion.

Make Oscillation Easy – Push and release in rhythm to oscillate for a more subtle way to train your body for inversion and get used to being upside down. Gently rocking while inverted encourages relaxation and a ‘pumping action’ in the spine that helps to rejuvenate the discs.

Release from Full Inversion – Simply place the heels of your hand on the ends of the Traction Handles and use as a “push-button” release lever to easily disengage the table from its ‘locked’ position.

CUSTOMIZE & ENHANCE YOUR RELIEF
Adjustable – The Traction Handles offer two settings to accommodate user size and desired stretch intensity.

Easy Assembly – Includes everything you need to add to your inversion table. Simply screw in to the Roller Hinge and start feeling the benefits.

Maximum Compatibility – Traction Handles work with any Teeter Inversion Table that pivots via the standard roller hinge system, including all EP-Series Tables. (Not compatible with the Contour L3 or L5).
