Extension Spring Yoke, For Tandem Hookup

Garage Door Extension spring yoke plate. Connect two extension springs together on one side of the garage door to double the lift on that side.
Tandem kits are designed to work with four spring systems. The kit is mounted to the ends of the springs that are closer to the door. On each side above the tracks the kit joins the ends of two springs to the pulley with the pulley fork. This allows the pulley to move forward and backward as the door closes and opens. Since the other ends of the springs are stationary and don't move, these ends are secured to the rear hangs with S-hooks or eye bolts.
