Rebar tying, with a twist! Loop ties are pre-formed with loops on either end where you insert a spinner and snug it up with by twisting it all together. Loop Ties come in bundles of 2500. Loop ties help speed up the rebar tying process. Rather than using tie wire and pliers, you can use loop ties and a spinner. With the pre-formed loops on either end of the ties, you can wrap up rebar much faster than with traditional tie wire. This is useful both on the site or in a warehouse to help keep the product in nice, neat bundles!
