I plan to use with 1/2 and 3/4 rings recommended for joining csip panels for concrete roofs as per tridipanel.com and covintec. com recommended for ship hulls, earthquake and storm proof. This is an alternative to the $500 air adjustment gun. or make a cable tie individually. A better alternative in the future might be a 6mm to 26mm electrical cable tie, but it's not available in Mexico (yet).
