The popular Hiatt Model 2010 handcuffs have been replaced by the new Safariland Model 8112131. This was Hiatt’s standard chain nickel handcuff and by far their biggest seller. Formerly made in Birmingham, England, they are now made in Fitzwilliam, New Hampshire. I think Safariland should have chosen an easier numbering system. Model 8112131 doesn’t exactly roll off the tongue, but they are good handcuffs and have the same special Hiatt features including backloading and 3 retaining bar pawl system. Heavy-duty construction with oversized rivet heads for added strength and side double locks; with two keys. Feature reinforced steel swivels for extra strength and durability. 23 locking positions, shackle diameter from 5 1/4 inches to 8 1/4 inches.
