Zinc plated steel 1 in. Medium Series 1 hole rigid/IMC conduit strap/Jiffy Clip®. Made in the USA.
Minerallac precision-made one-hole conduit and pipe straps are used where the load is too heavy for the standard Jiffy Clip. Clips have an inverted rib, providing more strength at the bend of the clip and holding the clip on the conduit, leaving both hands free to work.
