Next time you see one of these, we will know what it is.
Simpson Strong-Tie**'s new ITS top-flange I-joist hanger features a new Strong-Grip seat that securely holds the I-joist without any joist nails. Once the hanger is installed on the header, the I-joist is simply snapped down into place. According to the company, the ITS installs faster and uses fewer nails than any other engineered wood product top-flange hanger, and has the lowest installed cost. The ITS design also maintains superior allowable download capacities equal to or greater than the ITT for Douglas Fir and all SCL headers. The ITS can be used with most current I-joist sizes and with flange thicknesses from 1-1/8 inches to 1-1/2 inches.
Very few nails.
