Using these BNHYBR adjustable hickey bars is easy. First, select the right model according to your rebar and the task you need to do. If you need a simple round - end for general bending, choose the BNHYBR - 21401. For more heavy - duty prying or wrecking work, the BNHYBR - 21402 is your go - to. And if you need to chisel or shape the rebar in a particular way, the BNHYBR - 21404 is perfect. Adjust the length of the bar to suit your needs, and then use the adjustable angle head to grab the rebar firmly. Start bending slowly and steadily. When not in use, store the bars in a dry place to prevent rust. Regularly check the adjustable parts for any signs of wear or damage, and if needed, lubricate the moving parts to keep them working smoothly.
