Sure Ring Against Over Tightening
Hy-Lok Sure Ring is especially useful when you install Hy-Lok fittings in a small space such as in a cabinet where it is practically impossible to apply the standard installation procedures. (i.e., 1 1/4 turns or 3/4 turns from finger tight). It ensures sufficient tightening and protects over-tightening. For installation, inset the Sure Ring between the net and the body before assembly, and then tighten the nut until being blocked by the sure ring.
Available in a variety of sizes and in materials, Stainless Steel 316, Carbon Steel and Brass.
