Description
The All-O-Matic SKN-RD300 Swinger Arm Connecting Knuckle is a replacement linkage component designed to provide a secure pivot connection between the gate operator drive assembly and the swinger arm. This knuckle helps the swing arm articulate properly, supporting smooth and consistent gate movement during opening and closing cycles.
This service part is commonly used when the original arm connecting knuckle shows signs of wear, looseness, damage, or excess linkage play. Replacing a worn knuckle can help restore proper arm alignment, reduce unnecessary movement in the linkage, and improve the overall reliability of the swing gate operator system.
Ideal for routine maintenance or field repair, the SKN-RD300 is intended for use with compatible All-O-Matic SW-300 AC and SW-300 DC gate operator swinger arm assemblies. Always verify fitment with your specific operator model and linkage configuration before installation.
