When they are gone, they are gone!
Very limited stock. 10mm diameter J-bolt designed to create a secure suspension point in a wooden beam or joist up to 150mm/6" thick where you have access to the upper side. The J-shape means it will not unscrew under rotation like an eye-bolt since the short upright of the J is sunk into a second hole leaving only about 25mm/1" showing. Steel carabiner included.
