DoorKing 1100-120 Chain Master Link Extended #40

#40 Chain Master Link Extended for DoorKing Slide Gate Operators

The DoorKing 1100-120 is a genuine replacement chain master link extended designed for use with #40 drive chain in DoorKing slide gate operator systems. The master link connects two ends of a #40 chain, allowing for chain removal, replacement, or length adjustment without specialized tools. This is a commonly replaced maintenance component in chain-driven slide gate operators, typically needed when the existing master link shows wear, corrosion, or failure, or when the drive chain is being replaced entirely. Using a genuine DoorKing replacement ensures the link meets the dimensional and load tolerances required for the #40 chain drive system in your specific operator.
