The gap measure between is .5" and that's a snug 0.5" The strap is plenty sturdy. ( Contract work that requires inspection. I do not know if it's legal to bend them ). The bracket is plenty strong. I used them to attach cattle fence panels to a wall. 3/4" bracket and bend it in may be easier. ## Customer Reviews ### ⭐⭐⭐⭐⭐ works *by S***E on March 23, 2026* works good ### ⭐⭐⭐⭐⭐ Good hole hole strap for MC cable *by A***R on April 12, 2026* Holds MC cable very well.
