20 lb bottle J Bolt Kit.
The J-hook kit holds down the 20 lb LP gas bottles on the front of the pop up.
Comes with 2 J Hooks, washers, and wing nuts.
Measures 16-3/8 inches in overall length with 2 inches of threads at the bottom.
Installation Tip: The wing nuts feature a neoprene locking ring inside. This helps keep the LP tanks secured to the A frame of the pop up once installed. The wing nuts will be tight to start on the rod threads. Keep equal force on each side of the wing nut while turning. A pair of work gloves is recommended.
