Published specifications by club

Identifying the right model

• A compact chrome utility back with SRIXON on a raised central bar, ZXiU lettering low toward the toe, MAINFRAME low toward the heel, a 4 23 marking on the top line toward the toe and a small round dot at the far toe; the hosel reads i-FORGED.

What to check before using the reference

• Dunlop’s store labels this page ZXiU Utility Irons (2025) as a previous model; the current ZXiU page (product code MZXIUIRN27, 3.6 mm offset, MAINFRAME IQ lettering) has its own record.
• The table lists steel and graphite stock lengths separately (graphite ½ in longer); Length is the steel figure and the graphite length is given alongside.
• Srixon’s footnote says its published iron lengths now follow USGA and R&A measurement guidelines and read about ¼ in longer than before without the club itself changing.
