We’ve built a few hundred of these dumpable racks and they sure save time . If ya have a welder in the shop just weld a hook on ea side of ya forks . Use 2 smaller small chains with a clip like you have on on the end . Wrap 1 chain around the 4 by 4 about half way out then do the same on the other side so 2 separate lighter chains then take the other end of the chain with nothing on it and put it in the hook you welded on the top sides of the fork frame . We show it in a lot of our videos when we’re doing deliveries. It’s worked great for 100s of cords . Also from experience make sure to put some 4 by 4s on the ground to set the full pallet of wood on . Full pallets will sink into the ground or freeze down .

Why not just use a ratchet strap instead of chain. Adjustable and easier to handle
