FEATURES: Self-contained ball-and-spring device available in many sizes and forces. Available in steel, stainless steel, or Delrin®, all with a stainless steel ball. Locking element holds the unit securely in place after installation (steel and stainless only). Install and/or adjust from either end (when using the slot at the ball end, install with a Plunger Wrench to avoid over-compressing the spring). Note: the three smallest sizes, and all Delrin sizes, have no slot at the ball end. Made in USA.
