25mm Klick-lock Buckle & 45mm Tang & 3 Bar Slide SetBU183
ISC Klick-lock Buckles can only be opened when both release buttons are fully depressed, this feature reduces the risk of accidental opening. When loaded, ISC buckles cannot be opened by hand, (even when both buttons are depressed).
ISC Klick-lock Buckles are tested without webbing, in a straight line (direct pull), in line with the Z359.1 ANSI Standard.
This method gives an accurate, genuine measure of strength. Some manufacturers test the buckles as part of webbing loop which can give misleading results (see diagram).
