Description

Description
Receiver end caps fit over the end of quick-release ball lock pins to enable use when the receiving hole is out of tolerance or out of round. They replace cotter pins and hitch pins to allow quick, tool-free changes and field adjustments. Caps are manufactured from 300 series stainless steel. The Grip Length Reduction (H1) is the portion of the pin enclosed by the end cap and reduces the usable pin length by that amount.

Product Types
  • RC — End Caps — Plain — Inch (fits on ball lock pins, stainless steel)
  • RCT — End Caps — Tapped — Inch (tapped variant)
